The term packaging machinery includes a large variety of equipment. Packaging machinery can refer to finishing machines, carousels, power conveyors, liquid filling machines, capping equipment, or any other number of machines. The term packaging machinery can also refer to a complete packaging line manufactured for a specific project. In other words, the term packaging machinery is a very general term. When companies start looking for packaging machinery, few, if any, two companies look for the same thing.  

There are many things we need to take into account when we purchase a correct packaging machine. This is essential to choose the right one to benefit your project. Otherwise, it will spend you more cost and time for replacement and maintenance. As a professional packing machine manufacturer with over 30 years of experience, we will list the most five important considerations when purchasing a packaging machine. Hope this article can help you a lot.

Package

Once the equipment is determined to handle the product, the packager must move on to selecting the actual packaging to hold the product. Whether bottles and caps or other containers and closures, machines must be able to handle every component of the packaging. For automated machinery, the focus here will be on the conveyor system and, to a lesser extent, each machine through which a bottle or other container will pass. Obviously, the conveyor system must be able to efficiently transfer containers from one packaging stage to the next. The capping machine also needs to stabilize the bottles and adjust the torque or other capping mechanism to seal these bottles reliably at all times. The labeling machine needs to be able to orient and always place the label in the correct position. Therefore, before choosing packaging equipment, you must first choose a container and seal. 

Products

When looking for packaging machinery for any project, the first thing to consider is the product itself. The equipment must be able to handle the product to be packaged. Of course, the main focus of this analysis will be on filling machines, as they are often the only machines that actually come into contact with the product. The filling machine chosen needs to be able to handle the viscosity of the product as well as any other unique product characteristics. But stopping the analysis on the filling machine is wrong for many different products. For example, some aggressive chemicals simply do not interact well with stainless steel (the construction material of most packaging machines).   

Packaging range and products

When using multiple products or packages, it is necessary to consider each product as well as the combination of containers and seals. It would be a mistake to assume every time that because one product or package runs smoothly on a particular packer, all other products and packages will work properly. Going back to the filler, assume that a 16-ounce bottle and a 1-gallon bottle will both be filled on a machine with a submersible head. While the 16-ounce bottle will work perfectly on the filler, the gallon bottle may still have a problem. If the gallon bottle is tall, the fill head may not rise high enough to properly fill the container. If the gallon bottle is wide, the fill head may not be able to adjust left or right to accommodate multiple containers at once, severely reducing productivity.

Productivity

Knowing the productivity of a given product will help in selecting the appropriate level of automation for a packaging facility. Lower production facilities can be addressed with less space and desktop or semi-automatic packaging equipment and higher levels of manual labor. Production facilities with higher product requirements may need to scrutinize automated packaging equipment and ensure it can meet daily monthly or even annual demand. Likewise, in practice, packagers need to work closely with manufacturers to ensure that the equipment purchased meets the needs of consumers.

Future

Having equipment that meets current needs is usually the focus of packagers purchasing machines. But remember, almost everyone who packages a product expects future demand for that product to increase. Acquired packaging machinery should not become obsolete with the addition of some new retailer or consumer. Most packaging machinery can be upgraded and has the ability to grow as the company itself grows. Therefore, buying a packing machine or packaging line not only needs to suit your present needs but also your future needs.

Guide to buying packaging machinery.

Investing in new machinery can be a step on the path to growth and profitability. However, unless your approach is thoroughly planned and fully costed, there&#;s the very real risk of new machinery projects failing.

This guide highlights the issues you need to consider before committing to significant expenditure. It details the steps you should take for your investment decisions to deliver your goals. You will also find links to PPMA&#;s Machinery Finder to help you find suppliers of a multitude of different types of packaging machinery.

When do you need new packaging equipment?

All equipment has a finite life. In the case of packaging machinery, life expectancy is generally in the region of 10 to 15 years. Business owners, managers and operators will be very well aware if an ageing piece of equipment has slowed down, or needs increasing maintenance, or if it is creating damaged or imperfect packs.

If the bill for remedial work is too high, or if repair work is not going to make the machinery properly usable, it is time to replace it.

You may also need to add equipment to increase capacity to fulfil the demand from your clients or to prepare you for expansion into new markets. You may be bringing the packaging function in-house from external packers. Or you may be making your entry into the packaging world in a brand-new venture.

Whatever the background for buying new packaging equipment, the issues and activities you need to be absolutely clear about are:

• Business case
• Budget
• Specification
• Sourcing
• Scheduling
• Installation, testing and commissioning
• Training
• Maintenance and support

From the inception of a project involving a significant new capital investment, businesses need to commit to a thorough process involving key decision makers. It&#;s been said many times that the major cause of delays in projects is the time taken by the companies buying new equipment to reach internal agreements and make decisions.

Therefore, a thorough, organised approach from the outset will help avoid delays which can hold projects back and impact costs.

How to make a business case for new packaging machinery?

Well-run organisations will normally have a procedure for making a business case for any significant investment in new equipment. Many templates exist in the public domain including a thorough, downloadable business case template from gov.uk.

An outline structure for a business case is:

• Summary
• How the project fits with business objectives
• Costs and benefits
• Risks
• Financial case, including resources required
• Non-financial benefits
• How the project will be delivered including an outline schedule
• Conclusion

However formal or informal the actual presentation of the business case, time spent preparing it and considering the issues will increase the likelihood of a successful outcome for all.

Budgeting for new machinery.

The financial figures within a business case will give a firm idea of the expenditure needed for new machinery. The job of budgeting is to pin down where the money comes from, and how the spending fits in with the overall financial position of the business.

Some businesses will have an annual allocation for new equipment which could be used to cover costs. Others will operate on a case-by-case basis for investment. Whatever the approach to business finances, the project should not be a standalone consideration.

It may be that the money spent on one project means delaying another project. Competition for financial resources is part of business life, and the key factor in deciding what to spend on is likely to rest with the business cases put together for different investments.

To budget thoroughly, it is important too to drill down into the full costs over time using a net present value (NPV) approach. Ideally, project sponsors will have the support of a company&#;s finance team to ensure that NPV calculations are in line with the company&#;s thinking.

Key cost issues are:

• Maintenance
• Downtime
• Components
• Energy usage
• Residual value

The way the equipment is paid for is a further budgeting and cost consideration. Outright purchase is one option. But for less initial capital outlay, it is advisable to explore payment in instalments, and lease or hire arrangements. Each has its advantages, and your choice is likely to depend on the availability of finance within your organisation.

How to specify packaging machinery?

Once the business case and budget has been signed off, a clear and comprehensive specification has to be put together for the prospective equipment purchase. As a starting point, businesses should always define their requirements first, rather than being guided by the manufacturer&#;s equipment specifications.

Key specification issues.

Building a complete specification begins with clarity about the required function of the packaging machinery. What products is it required to pack and in what type of packaging?

If the project is a replacement for an existing machine, the answers may be very straightforward, but new equipment may present opportunities for enhanced functionality.

For example, machinery which could only handle one type of product, could be replaced by a machine designed with the flexibility to package a range of sizes and types of products. Or, there may be a case for equipment with a larger capacity, such as a twin-chamber vacuum packer replacing a single-chamber machine.

The three overriding criteria for equipment specifications are speed, capacity and flexibility. The nature of your business will dictate what is required in terms of:

• The rate of packing
• The number of packs produced
• The type of products handled and the type of packs produced

Within the specification, the issue of quality also needs to be addressed, with minimal tolerances for spoilage, as well as targets for time in operation. All machines require downtime for maintenance, but the design of the machine and the quality of its component parts will have a major influence on how long any machine is offline.

The efficiency of equipment can be measured by taking the &#;official&#; rates of packing quoted by the manufacturer and comparing them to the actual rates achieved over a specific period of time.

For example, a manufacturer may quote a packing rate of 1,000 packs a day, but if the average day rate is 900 packs a day, the machine is only delivering 90% efficiency. When it comes to discussing equipment with potential suppliers, it&#;s important to delve into the efficiency of the machinery you are thinking about buying.

Specification of each part of the packaging machinery.

Within a packing machine, individual parts of the equipment perform specific functions, and a specification for each one of these is part of the buying process. The importance of doing so is that the machinery as a whole is limited by the performance of its slowest, or least reliable, part.

The core components of packaging machines are:

• Conveyors including chains, belts and drivers - Horizontal conveyors are the principal method of moving products and packs through the packaging operation. Key issues for conveyors are the type of drive such as electric motor or less commonly compressed air, and whether the conveyor uses belts or rollers.
• Container handling 

  - Packaging containers range from flexible bags to glass bottles and metal containers. Each type of container needs to be handled either manually or by equipment based on push feeding, simple grabbers or more complex robotic arms.

• Liquid fillers (volume or level)

  - Liquid filling can rely on gravity or pumping, regulated by controls which fill by a measured volume level or up to a specified level through a doser.

• Solid fillers (weight, volumetric, count)

  - Solids are measured by checkweighers, volume controls or an automated count of the number of solid units going into each pack. Loose-flowing powders and grains use similar filling equipment to liquids.

• Capping

  - Capping machines feed circular disks from a hopper for crimping by means of a chuck around bottle tops.

• Vacuums and modified atmospheres

  - Vacuum packing is a key technique for extending the shelf life of food products, for protecting medicines and other products from moisture and other potential damage. Pumps are used to create a vacuum. Modified atmosphere packaging uses pumps to displace oxygen with inert gases (such as nitrogen) to prevent the deterioration of food products.

• Sealing

  - Airtight sealing of packs in film is frequently achieved by means of a straight or L-shaped sealing bar which is heated to bond two film surfaces which are sometimes glued. Other types of sealing include the use of ties and clips, and the capping of bottles and cans.

• Wrapping

  - Wrapping in film is an essential part of packaging. Heat-shrinkable film is wrapped around a product and then shrunk under heat to form a tight wrap. Stretch wrap film is pulled around a product, and the film&#;s adhesive property creates a close-fitting barrier to protect the product. Wrapping is used in packaging for items ranging from bite-sized foods to stacked pallets of cartons.

• Form fill seal (FFS) machines

  - For complete packaging solutions, FFS machines begin with the creation of packs (bags, pouches or cartons), the filling with products, enclosure and wrapping, through to end-of-line operations such as cartoning and palletising.

• Labelling

  - Labels have a hugely important role in packaging for purposes ranging from product codes and logistics information through to consumer-facing information such as best before dates, marketing messages and branding. The options for labelling run from the application of a simple label from a reel to bespoke, data-driven label printing and application.

• Inspection equipment

  - Inspection equipment performs a critical role in ensuring the quality, consistency and safety of packaging. Visual inspection by human operators is used in many packaging operations across the manufacturing sector. However, there are increasing options based on sophisticated 2D and 3D machine vision systems. Further advanced equipment includes magnetic and x-ray inspection tools used to identify metallic fragments in food products.

• Cartoning and case erectors

  - As packages are completed, they are frequently placed in cartons which have been constructed within the packaging plant by a case erector. These cartons are positioned manually or automatically at the end of the packaging line. They&#;re filled with products by equipment based on gravity, conveyors, grippers, robotic arms and a range of other pick and place approaches. Filled cartons and cases are then usually forwarded to pallets for onward transport or storage.

Including a clear specification for each part of the equipment will help buying decisions and help suppliers understand exactly what you require. For buyers looking for guidance from suppliers, understanding the capabilities of each part of the equipment will result in more informed purchases.

Machinery location

It&#;s essential to be clear about the exact location of the machinery. Issues such as load bearing ability cannot be overlooked, nor the heating, ventilation and air conditioning in place within the packaging plant.

Dust control and dampness are further factors which can affect machine performance and need to be controlled in line with the operating environment required by the machinery.

Sourcing packaging machinery.

With a solid specification completed, it&#;s time to approach packaging machinery manufacturers and equipment dealers. The choices are numerous unless you are in a very specialised field of packaging, such as dangerous substances.

Who you approach for quotations is likely to be based on what you have heard from business contacts and what your research tells you about potential suppliers. The umbrella of the Automate UK can help you in your search, providing plenty of details online. This includes contact information and our web tool Machinery Finder besides the PPMA Group and PPMA Show websites.

New or second-hand?

New equipment is very often the first consideration for buyers, with a large number of equipment manufacturers to choose from, and a much larger number of machine types and models.

New machinery may be available with more finance options, including leasing and rental. However, lead times can be lengthy, since manufacturers tend not to have &#;off the shelf&#; equipment offerings, except for smaller machines and components.

However, your business should not automatically rule out buying used packaging machines, because they could prove to be your most cost-effective option. Previously owned equipment is generally immediately available, and some have, in fact, never been used.

Pre-owned or not, second-hand machinery needs to be:

• Aligned with your specification
• With unblemished provenance
• Available for inspection and testing
• Defect free
• Supplied with a warranty, or be returnable

Furthermore, if modifications to second-hand equipment are required, you need to know what they will cost and how they will be done.

Create a short list of potential suppliers.

After completing your research, send out a request for quotation to a limited number of potential suppliers. Three to five will probably be enough and will allow you to assess each of their offerings without being overwhelmed. If none convince you, a further round of companies can be contacted.

Scheduling

As part of the discussion with potential suppliers, you need to cover the schedule for supply, installation and commissioning. Depending on the scale and complexity of the equipment, you should expect a 20 to 30 week lead time from signing contracts.

Allow further time for the delivery of the equipment, which may be a few days if it&#;s coming from within the UK to a UK site, and longer if it&#;s coming from Europe, the Americas or Asia instead.

The responsibility for managing schedules is usually best placed with a project manager appointed to oversee a successful outcome of the project. The project manager should be involved from the early stages, but will fully come into their own when the project goes live.

GANTT charts can be used to track and report progress, and to highlight blockages in the project which the project manager can focus on removing.

Installation, testing and commissioning.

With good preparation and scheduling, installation should proceed with minimal problems under the control of the project manager working with the vendor team. There is, however, a need for clear staging posts for the new equipment.

Always seek a contractual agreement covering penalties for late or imperfect supply, as well as the obligations of the purchaser to sign off stages without delay.

Full and thorough testing needs to take place to ensure that the equipment works as set out in the purchase agreement. It&#;s usual for various snags to be put right during the testing phase, which could involve modifications of minor parts of the equipment to ensure it operates as specified. Formal sign-offs by the buyer are likely to be required before the machinery is commissioned and ready to start full operations.

Training

Once the machine is ready to be used, supervisory and operating staff need to be fully trained, usually by the machinery supplier or their appointed trainers. The company buying the equipment needs to select staff who are suitable for the work (including, for example, lifting off heavy cartons at the end of the packaging line).

Training on most packaging equipment is relatively short. Although the time needed can be extended if there are complex controls and programmes to manage. A key part of the training will cover all health and safety issues specific to the new machinery.

Post installation support

After the equipment has been set up and signed off, the vendor is frequently contracted to provided ongoing support to their client. This can include a maintenance schedule and availability for resolving breakdowns and malfunctions. Details about the support are usually specified in a service level agreement which forms part of the purchase contract.

How much does a packaging machine cost?

The cost of packaging equipment varies with the type of materials and technology used, and the size of the machinery. Simple entry-level machines for small, low-volume packaging operations can be in the low hundreds of pounds.

At the top end of the market, fully automated systems can come with a bill in the high tens of thousands of pounds, or even more. Leasing is an increasingly popular option for capital equipment and is a route to explore for packing solutions.

How many types of packaging machines are there?

Packaging machines have been developed for every category and sub-category of product. So in total, there is an almost limitless number of types of machines. However, they all fall into two principal types: primary and secondary.

Primary packaging is the packing material that contains the product itself, such as a foil wrapper for confectionery, a bag for breakfast cereal, or a can for a beverage. Secondary packaging refers to the next layer of packaging material such as film wrap around confectionery or a carton for bags of cereal, or a paperboard tray and shrink film for a group of canned drinks.
