A paper bag is a bag made of paper, usually kraft paper. Paper bags can be made either with virgin or recycled fibres to meet customers' demands. Paper bags are commonly used as shopping carrier bags and for packaging of some consumer goods. They carry a wide range of products from groceries, glass bottles, clothing, books, toiletries, electronics and various other goods and can also function as means of transport in day-to-day activities.

History

[

edit

]

The first machine to mass-produce paper bags was invented in 1852 by Francis Wolle, a Pennsylvania schoolteacher.[1] Wolle and his brother patented the machine and founded the Union Paper Bag Company.

In 1853, James Baldwin, papermaker of Birmingham and Kings Norton in England, was granted a patent for apparatus to make square-bottomed paper bags. Thereafter he used an image of a flat-bottomed bag as his business logo.[2]

In 1871, inventor Margaret E. Knight designed a machine that could create flat-bottomed paper bags, which could carry more than the previous envelope-style design.

In 1883, Charles Stilwell patented a machine that made square-bottom paper bags with pleated sides, making them easier to fold and store.[3][4] This style of bag came to be known as the S.O.S., or "Self-Opening Sack".[5]

In 1912, Walter Deubener, a grocer in Saint Paul, Minnesota, used cord to reinforce paper bags and add carrying handles. These "Deubener Shopping Bags" could carry up to 75 pounds at a time, and became quite popular, selling over a million bags a year by 1915. Paper bags with handles later became the standard for department stores, and were often printed with the store's logo or brand colors.

Plastic bags were introduced in the 1970s, and thanks to their lower cost, eventually replaced paper bags as the bag of choice for grocery stores.[6] With the trend towards phasing out lightweight plastic bags, though, some grocers and shoppers have switched back to paper bags.[7]

Kroger decided to look into switching to plastic in 1986, because they could save 3 cents per bag. There was a meeting held with employees at Store 100, Toledo, Ohio, asking for ideas for the store, & management dropped a cardboard box on the table. After looking at the product one of the baggers burst out laughing & said, "so you're going to switch to plastic to save 3 cents per bag, but now you need 2 baggers at each register, 1 to hold the bag open & 1 to put the groceries in, or you will have a line all the way to the back of the store. The panicked & asked him how to fix it.. & he asked for a wire hanger & a paper hole punch. Then drew the plastic bag dispenser on paper. His name was Joseph Poirier. So essentially, he invented both the plastic bag with holes in the arm & the plastic bag dispenser on the spot, & he was still in high school.

In 2015, the world's largest paper shopping bag was made in the UK and recorded by Guinness World Records.[8] Also in 2015: The European Union adopted directive (EU) 2015/720, that requires a reduction in the consumption of single use plastic bags per person to 90 by 2019 and to 40 by 2025.[9]

In 2018, the “European Paper Bag Day” was established by the platform The Paper Bag, an association of the leading European kraft paper manufacturers and producers of paper bags. The annual action day takes place on 18 October and aims to raise awareness among consumers about paper carrier bags as a sustainable packaging solution. It was launched to encourage more people to act responsibly and use, reuse and recycle paper bags. With different activities on local level, the association wants to open a dialogue with consumers and give them revealing insights about paper packaging.[10]

In April 2019, the European Union adopted Directive (EU) 2019/904 of the European Parliament and of the Council of 5 June 2019 on the reduction of the impact of certain plastic products on the environment.[11]

Paper sack

A multiwall bag of dog food Paper sacks containing cement

A paper sack is a type of paper bag that can be constructed of one or several layers of high quality kraft paper, usually produced from virgin fibre. Paper sacks can also be referred to as industrial paper bags, industrial paper sacks, shipping sacks or multi-wall paper bags or sacks. They are often used for packaging and transporting dry powdery and granulated materials such as fertilizer, animal feed, sand, dry chemicals, flour and cement. Many have several layers of sack papers, printed external layer and inner plies.[12] Some paper sacks have a plastic film, foil, or polyethylene coated paper layer in between as a water-repellant, insect resistant, or rodent barrier.

Multi-wall paper sacks are designed to provide strong product protection, with high elasticity and high tear resistance, for products with high demands for safety and durability. Information such as instructions, logos or trademarks can be printed on the resistant outer surface.[13] Plastic films [13] or different dispersions are sometimes used as inner layers or coatings to provide a barrier against moisture, water vapour, grease, oxygen, odours and bacteria. Paper sacks are produced on paper sack converting machines consisting of tuber and a bottomer.[14]

There are two basic designs of bags: open-mouth bags and valve bags. An open-mouth bag is a tube of paper plies with the bottom end sealed. The bag is filled through the open mouth and then closed by stitching, adhesive, or tape. Valve sacks have both ends closed and are filled through a valve. A typical example of a valve bag is the cement sack.

Properties

[

edit

]

Paper sacks are usually made of Kraft paper having the advantage of being soft and strong at the same time. The stretch or elongation increases the energy required to break the material. They carry and protect products up to 50 kg, and adapt easily to the nature of their contents and to handling constraints. Depending on the product, the weight ratio of a paper sack to its contents can be up to 1:250.[15] The strength is due to the arrangement of the fresh fibres used in kraft paper production. Due to the fibres bonding together in production not only the strength, porosity and elasticity, but also the tear-resistance improves.[16]

One of the natural and unique characteristics of sack kraft paper is its porosity. Acting as a filter material, high-porosity paper enables the air used in the filling process for dry powdery goods to escape very quickly, without the need for air extraction systems. This makes it possible to achieve filling speeds of up to 3,5 sec for a 25 kg sack.[15]

Thanks to different paper sack constructions with glue, barrier, layer or surface concepts, paper sacks can also be moisture resistant.[16] All moisture-proof sacks are compatible with regular paper sack filling machines. In especially adverse weather conditions, an extremely thin bioplastic, plastic or other adequate barrier film can be part of the surface layer in the paper sack construction for particularly effective protection.

Added barrier film liners can also extend the shelf life in a range of different conditions. There are many different sack constructions especially designed to offer a good shelf life when paper sacks are exposed to extreme conditions such as damp, moisture, light, oxygen or carbon dioxide. Also, the correct storage and handling of paper sacks along the supply chain has a positive influence on their shelf life.[17]

Paper sacks also provide an outlet for promotional messages and sophisticated printing designs. Due to their natural, non-slippery texture and their construction, paper sacks can safely be handled, stacked, palletized and stored. User-friendly opening systems, such as a tear-open flap, allow quick and clean access to the product without the use of additional tools such as knives.

Construction

[

edit

]

Standard brown paper bags are made from kraft paper. Tote-style paper carrier bags, such as those often used by department stores or as gift bags, can be made from any kind of paper, and come in any color. There are two different styles of handles for paper carrier bags: flat handles and cord handles. Paper carrier bags made from virgin kraft paper are developed especially for demanding packaging. Paper bags can be made from recycled paper, with some local laws requiring bags to have a minimum percentage of post-consumer recycled content.[18]

Paper bags can be made to withstand more pressure or weight than plastic bags do.

Sack paper manufacturing

[

edit

]

Wood pulp for sack paper is made from softwood by the kraft process. The long fibers provides the paper its strength. Sack paper is then produced on a paper machine from the wood pulp. Both white and brown grades are made. The paper is microcrepped to give porosity and elasticity. Microcrepping is done by drying with loose draws, allowing the fibres to shrink. This is causing the paper to elongate 4% in machine direction and 10% in cross direction before busting.[19] Machine direction elongation can be further improved by pressing between very elastic cylinders causing more microcrepping.[19] The paper may be coated with polyethylene (PE) or different dispersions to ensure an effective barrier against moisture, grease and bacteria. A paper sack can be made of one or several layers of sack paper depending on the toughness needed.

Paper sack manufacturing

[

edit

]

The production of paper sacks is an entirely automatic process. It is divided into two main parts: tube forming and bottom folding. The sack kraft paper used for the production is printed on its way to the tube forming.[20] In the first step of tube forming, paper and film (if applied) can be vent-hole perforated to improve the air permeability. They are combined by glue at the cross-pasting unit afterwards and glue is then also applied at the edge of the paper layers. In the next step, paper and film are formed into a continuous tube. Individual tubes are separated by a perforating knife. After accumulating these individual tubes, they are bundled at the shingling conveyer. These bundles are transported from the tuber to the bottomer. There, at least one end of the tube is folded to a bottom that creates the paper sack. Afterwards, the paper sacks are transported to a press section, which ensures efficient paste distribution and adhesion. The production process is monitored by electronic inspection systems and machine operators.[14]

The production process slightly varies depending on the type of sack. All paper sacks are tailor-made and cater to the specific area of usage, product type and transportation needs.

Sack types and sizes

[

edit

]

There are many different types of paper sacks available for the various end uses. The most common sack types are valve sacks, pinch bottom sacks, SOS (self opening sacks) sacks [21] and (pasted) open mouth sacks.

Valve sacks have a valve for filling and sealing in a corner of the paper sack. The valve system in a corner of the sack allows high-speed filling with automatic closing as the sack is filled to its capacity. This type of sack is used to pack especially powdered products such as cement, flour and cocoa.

The pinch bottom sack is a usually leak-proof open mouth sack, that is used for products such as chemicals or food stuffs which must be particularly protected during transport and storage.

An SOS sack has a high stability and makes quick open mouth filling easy, while also being able to be reclosed. SOS sacks are used for granulated products such as food products or animal feed. They have a rectangular bottom and high stability faculties and can also be used as a compost sack or refuse sack. Pasted open mouth sacks can also be SOS sacks and differentiate themselves due to their glued bottom area, which increases their strength.[22]

Paper sacks are available in different sizes and can carry loads up to 50 kilos.[23] The capacity is variable and paper sacks also come in a variety of calipers, basis weights, and treatments.

Single layer

Two small paper bags – Bottom: flat gusseted bag. Top: square bottom, self-opening

Paper shopping bags, brown paper bags, grocery bags, paper bread bags and other light duty bags have a single layer of paper. A variety of constructions and designs are available. Many are printed with the names of stores and brands. Paper bags are not waterproof. Types of paper bag are: laminated, twisted, flat tap. The laminated bag, whilst not totally waterproof, has a laminate that protects the outside to some degree.[24]

Quality standard and certification

[

edit

]

Paper bag durability can be measured in accordance with the European test standard EN13590:2003. This standard is based on scientifically conducted studies and helps retailers to avoid poor-quality carrier bags. The quality certification system for paper bags is based on this standard. The test method subjects the carrier bag to heavy weights while being lifted repeatedly. The size of the paper bag is taken into account because the larger its volume, the heavier the load it must be able to carry. As a result of the certification, the paper bag is marked with the weight and volume it may carry. It is wise to choose a tested and certified paper bag.

Testing and assurance

[

edit

]

Filled bags or sacks can be evaluated in the field by careful observation. Laboratory package testing is often conducted using drop testing,[25] shock table testing,[26] puncture testing, etc.

Paper sacks for food require specific quality assurance and hygiene management along the entire supply chain, as they must be in line with several national and international standards regarding the safety and hygiene of the stored food products. All materials of the sack need to be taken into account to fulfil these requirements. In Europe, there are several mandatory procedures to collect, evaluate and document all necessary information. Under certain conditions, migration testing and the issuing of compliance documents is demanded. Most of those requirements concern the conditions of use, storage time and temperature. Information on these aspects from all suppliers is a prerequisite.[27]

Sustainability

[

edit

]

The raw material used in papermaking – cellulose fibre extracted from wood – is a renewable and natural resource. However, environmental concerns have been raised about types of wood harvesting, such as clearcutting. Due to their biodegradable characteristics, paper bags degrade in a short period of time (two to five months).[28] When using natural water-based colours and starch-based adhesives, paper bags do not harm the environment.

Most paper bags that are produced in Europe are made from cellulose fibres that are sourced from sustainably managed European forests. They are extracted from tree thinning and from process waste from the sawn timber industry. Sustainable forest management maintains biodiversity and ecosystems and provides a habitat for wildlife, recreational areas and jobs. This sustainable forest management is proven in the FSC® or PEFC™ certifications of paper products. Consumers can look for the FSC and PEFC labels on their paper bags to make sure they are made from sustainably sourced fibres.

As a wood product, paper continues to store carbon throughout its lifetime. This carbon sequestration time is extended when the paper is recycled, because the carbon remains in the cellulose fibres.

Paper bags can be used several times. Paper bag manufacturers recommend reusing paper carrier bags as often as possible in order to further decrease the environmental impact.

The carbon footprint of an average European paper sack is analysed since 2007. The studies have shown continuous improvement, as the carbon impact of paper sacks has been reduced by 28% in eleven years between 2007 and 2018. In 2018, the carbon footprint of an average European paper sack from cradle-to-gate is 85g CO2e per sack. If the biogenic emissions and biogenic removals were included in the analysis, it would amount to -35g CO2e per sack, which means that paper sacks have a positive impact on the environment.[29]

Recycling

[

edit

]

Paper bags are highly biodegradable and recyclable, and hence does not pose the same environmental footprint as plastic bags do. The fibres are reused 3.6 times on average in Europe, while the world average is 2.4 times.[30]

Plastic or water-resistant coatings or layers make recycling more difficult.[31] Paper bag recycling is done through the re-pulping of the paper recycling and pressing into the required shapes.

Safety

[

edit

]

Compared to plastic bags, paper bags present less suffocation risk to young children or animals.

Branding and marketing

[

edit

]

Paper shopping bags can be used as a vehicle to project the brand image of retailers. Paper is very tactile due to its texture and shape. Its print quality and color reproduction allow for creativity in advertising and development of the brand image. Furthermore, they achieve maximum visibility and great appreciation from customers. Using paper bags gives a signal of commitment to the environment and by using packaging made from renewable, recyclable and biodegradable sources, retailers and brand owners contribute to reducing the use of non-biodegradable shopping bags. Paper carrier bags can be a visible part of corporate social responsibility, and they are in line with a sustainable consumer lifestyle.[32]

While brown is the most common paper bag color (as it is the natural color of the wood fibre used to make the paper), the term "brown bag" (especially as a verb) refers to two specific and distinct practices:

The first form of "brown bagging" refers to bringing food from home (regardless of the actual container used) instead of buying a meal at or near one's destination. Most often, it means bringing a packed lunch to school or work. For example, a 1983 study reported that America had 60 million "brown baggers."[33]

Individuals may choose to brown bag to save money; if options to buy food are limited or absent; or to accommodate medical, religious, or lifestyle dietary requirements (e.g. low-fat or low-salt, kosher or halal, vegetarian or vegan). Additionally, while "a substantial minority of brown baggers have access to microwave ovens or refrigerators," those who do not need to ensure their food can stay fresh until mealtime without refrigeration (possibly bringing their own, via ice packs and thermal bags), and be ready to eat without being reheated.[33]

The noun form of the term included in the Merriam-Webster dictionary in 1950 refers to use of a paper bag instead of a lunch box. William Safire traces this to an article in Time magazine.

The second form of "brown bagging" involves drinking alcohol in places where it is not legal to do so (such as a public park, or a venue without a liquor license) while using a brown paper bag (or a black plastic bag, or other suitably opaque covering) to conceal the bottle or can. While it's usually an open secret that a drink handled like this almost always contains alcohol (as there's little reason to hide other drinks), depending on local laws, this can minimize the chance of legal consequences. If there's no law against generally keeping open containers in bags, then doing so does not, in and of itself, give police probable cause to search a bag for alcohol.[34]

Anti-brown-bag law in New York, USA

[

edit

]

In 1967, it was stated that "brown-bagging is the genteel disguise ... by a patron to furnish his own liquor when he dines at the local restaurant".[34]

In 1985, the New York State Liquor Authority pushed for legislation (informally referred to as "the anti-brown-bag law"[34]) to prevent patrons from bringing alcoholic beverages into food establishments that do not have a liquor license. New York City Mayor Ed Koch, having been "arrested" for doing so months earlier, denounced the effort.[35]

Brown Bag Report

[

edit

]

The advertising agent who, prior to the Marlboro Man,[33] developed ads for the product as a filtered "feminine brand"[32][36]: p. LB-6  in 1981 developed "The Brown-Bag Report" with funding from Swift, Carnation, General Mills and American Can.

Symbolism

[

edit

]

While in the United States the lunch box or lunch pail has been used as a symbol of the working class, Safire wrote: "In the metaphor of the modern worker, the brown bag has replaced the lunch pail."[34]

About a third of the brown baggers are schoolchildren.[33]

The "Brown Paper Bag Test" formed part of a colorist discriminatory practice in African-American history, in which an individual's skin tone was compared to the color of a brown paper bag.[37]

Paper bags are occasionally worn over the head as symbol of embarrassment.[38]

Associations

[

edit

]

The platform The Paper Bag consists of leading European paper manufacturers and producers of paper bags. It was created in 2017 to represent the interests of the European paper bag industry and to promote the advantages of paper packaging. The Paper Bag is steered by the organisations CEPI Eurokraft and EUROSAC.

EUROSAC is the European Federation of multiwall paper sack manufacturers. It was created in 1952 and is headquartered in Paris. It represents over 75% of European paper sack manufacturers. Its members operate in 20 different countries. Sack manufacturers from all continents and bag manufacturers also contribute to the federation as corresponding members, and more than 20 suppliers (paper, film, machine or glue manufacturers) are registered as associate members.

CEPI Eurokraft is the European Association for producers of sack kraft paper for the paper sack industry and kraft paper for the packaging industry. It was established in the 1930s to represent the Swedish, Norwegian and Finnish kraft paper manufacturers and now has eleven member companies in twelve countries.

Other uses

[

edit

]

Paper bags are commonly used for carrying items. However, they have been used for other purposes. In 1911, the English chef Nicolas Soyer wrote a cookbook, Paper-Bag Cookery, about how to use clean, odorless paper bags for cooking, as an extension of the en papillote technique and an alternative to pots and pans.[39][40]

All About The Paper Bag: Its History, Inventors and Types Today

The big brown paper bag has a long, interesting history.

Brown paper bags have become a fixture in our daily lives: we use them to carry groceries home, tote our department store purchases, and pack our kids’ lunches. Retailers use them as a blank canvas for their branded product packaging. Creative trick-or-treaters even wear them as masks for Halloween. It’s easy to forget that someone, long ago, had to invent them!

 

 

As with the best inventions, the paper bag filled a need people didn’t know they had. Before the paper bag, baskets, bowls, and other containers were the main storage solution in every home and store. You can imagine, then, that the creation of a convenient, disposable container was revolutionary. Business owners could stock stacks of these bags at their stores, and their low cost and ease of use made them widely accessible for shoppers of even modest means.

So, just how did this seemingly ordinary invention earn its place in the hearts (and hands) of the everyday consumer? A glimpse back at the history and evolution of the paper bag offers a clue.

 

The Innovators Who Gave us the Paper Bag

For centuries, sacks made of jute, canvas, and burlap were the primary method of holding and moving goods throughout the British Empire. The main benefit of these materials was their sturdy, durable nature, but their production proved both time-consuming and expensive. Paper, on the other hand, could be produced at a much lower cost, and soon became the preeminent material for portable bags along trade routes.

Since its introduction in the 1800s, the paper bag has undergone numerous upgrades thanks to a few clever innovators. In 1852, Francis Wolle invented the first machine to mass-produce paper bags. While Wolle’s paper bag looked more like a large mailing envelope than the grocery store mainstay we know today (and thus could only be used to tote small objects and documents), his machine was the catalyst for the mainstream use of paper packaging.

The next important step forward in the design of the paper bag came from Margaret Knight, a prolific inventor then working for the Columbia Paper Bag Company. There, she realized that square-bottomed bags, rather than Wolle’s envelope design, would be more practical and efficient to use. She created her paper-bag making machine in an industrial shop, paving the way for the widespread commercial use of paper bags. Her machine proved so profitable that she would go on to found her own company, the Eastern Paper Bag Company. When you bring food home from the supermarket or purchase a new outfit from the department store, you’re enjoying the fruits of Knight’s labor.

These square-bottomed bags were still missing a classic component of the paper bag that we know and love today: pleated sides. We can thank Charles Stillwell for this addition, which made the bags foldable and thus easier to store. A mechanical engineer by trade, Stillwell’s design is commonly known as the S.O.S. bag, or “self-opening sacks.”

But wait — there’s more! In 1918, two St. Paul grocers by the names of Lydia and Walter Deubener came up with an idea for yet another improvement to the original design. By punching holes into the sides of paper bags and attaching a string that doubled as a handle and bottom reinforcement, the Deubeners found that customers could carry almost 20 pounds of food in each bag. At a time when cash-and-carry groceries were replacing home delivery, this proved a crucial innovation.

 

What Paper Bags Are Made Of

So just what materials is a paper bag actually composed of? The most popular material for paper bags is Kraft paper, which is manufactured from wood chips. Originally conceived by a German chemist by the name of Carl F. Dahl in 1879, the process for manufacturing Kraft paper is as follows: the wood chips are exposed to intense heat, which breaks them down into solid pulp and byproducts. Then the pulp is screened, washed, and bleached, taking its final form as the brown paper we all recognize. This pulping process makes Kraft paper particularly strong (hence its name, which is German for “strength”), and thus ideal for carrying heavy loads.

 

What Determines How Much A Paper Bag Can Hold?

Of course, there’s more to picking the perfect paper bag than just the material. Particularly if you need to carry bulky or heavy items, there are a few other qualities to consider when selecting the product that will best serve your needs:

 

Paper Basis Weight

Also known as grammage, the paper basis weight is a measure of how dense paper is, in pounds, related to reams of 500. The higher the number, the denser and heavier the paper.

 

Gusset

A gusset is a strengthened area where material has been added to reinforce the bag. Gusseted paper bags can accommodate heavier items and are less likely to break.

 

Twist Handle

Made by twisting natural Kraft paper into cords and then gluing those cords to the insides of the paper bag, twist handles are typically used with gussets to increase the weight a bag can carry.

 

Square-Bottomed vs. Envelope-Style

While Wolle’s envelope-style bag was later improved upon, it’s still very useful for certain businesses and widely used in our postal system. If you’re looking to accommodate larger items, Knight’s square-bottomed paper bag may be a better fit for your needs.

 

A Style for Every Need: The Many Types of Paper Bags

The design of the paper bag has come a long way since Francis Wolle, continuing to evolve to meet consumer demands for a more streamlined, easy-to-use product. Here’s a taste of the wide selection of paper bags that are available for business or personal use:

 

S.O.S. Bags

Designed by Stillwell, S.O.S. bags stand on their own while items are loaded into them. These bags are school lunch favorites, known for their iconic Kraft brown tint, though they can be dyed a variety of colors.

 

Pinch-Bottom Design Bags

With open-mouth designs, pinch-bottom paper bags stay open just as S.O.S. bags do, but their base features a pointed seal similar to an envelope. These bags are widely used for baked goods and other food products.

 

Merchandise Bags

Merchandise bags are usually pinch-bottom paper bags and can be used to hold everything from craft supplies to baked goods and candy. Merchandise bags are available in natural Kraft, bleached white, and a variety of colors.

 

Euro Tote

For added sophistication, the Euro Tote (or its cousin, the wine bag) comes decked out with printed patterns, embellished glitter, corded handles, and lined interiors. This bag is popular for gift-giving and special packaging at retail outlets and can be outfitted with your brand’s logo through a custom printing process.

 

Bakery Bags

Similar to pinch-bottom bags, bakery bags are ideal for food products. Their design preserves the texture and taste of baked goods, such as cookies and pretzels, for longer.

 

Party Bag

Celebrate a birthday or special occasion with an attractive, fun party bag filled with candy, mementos, or small toys.  

 

Mailing Bags

Francis Wolle’s original envelope-style bag is still used today to protect mailed documents or other small items.

 

Recycled Bags

For the environmentally minded, the Kraft bag is an obvious choice. These bags are generally composed of anywhere from 40% to 100% recycled materials.

 

The Paper Bag Continues to Make Waves

Throughout its history, the paper bag has passed from one innovator to another, improved again and again to make it easier to use and cheaper to produce. For a few savvy retailers, however, the paper bag represented more than just a convenience for customers: it has also become a highly visible (and highly lucrative) marketing asset.

Bloomingdale’s, for example, breathed new life into the classic with its take, known simply as the “Big Brown Bag.” Marvin S. Traub’s twist on the Kraft bag was simple, attractive, and iconic, and its creation transformed the department store into the behemoth it is today. Meanwhile, Apple opted for a sleek, white version embossed with the company’s iconic logo (so groundbreaking was the design, they ventured, that it deserved its own patent).

Even as plastic floods the market, paper bags have stayed the course and proven their value as a dependable, cost-effective, and customizable solution for small businesses and behemoths alike. Feeling inspired? Create your own customized paper bags with Paper Mart today!
