How to Choose the Right Surface Protection Film ...

The name surface protection film kind of says it all—it’s designed to protect critical surfaces from scratching, marring, abrasions, UV exposure, or dirt and contamination. Popular and successful due to its strength and durability, protective film is actually an adhesive tape. It’s produced from thin film layers bonded together to create a barrier, guarding everything from a building’s glass to anything else requiring under-construction protection. For instance, it’s the shrink-wrap plastic that comes affixed to your new refrigerator, and it’s the roll of material used to cover and protect the surface of fabricated parts, especially in the automotive industry. Additionally, it is extensively used by manufacturers of metal and plastic sheets, providing scratch resistance while also reducing the penetration of sunlight and UV rays.

10 Questions To Ask Before Choosing the Right Surface Protection Film

To ensure you get the right protective film for your applications, make sure to ask these key questions.

1. Will the film be applied to a rough or a smooth surface? Rougher surfaces, due to their increased surface area, require a thicker adhesive.
2. Is the surface area clean and dry? Dirty application conditions can lead to unacceptable results. Embedded materials and unnecessary debris can adversely affect a protective film's performance.
3. Will the surface be painted or have a coating? Chemical reactions can occur between adhesives and coatings, particularly the longer they remain in contact with each other.
4. What type of surface needs protection? Wood, stone, metal, glass, plastic, or ceramic all require different adhesives for optimal performance.
5. Will the film be exposed to elevated temperatures? Most rubber-based adhesives fail at temperatures above 150°F. In contrast, acrylic adhesives function well up to 350°F, while silicone adhesives can handle up to 500°F.
6. Will the film be used outdoors? If so, for how long? The sun’s UV rays can damage adhesives over time. Protective films will not only yellow but may become stiff and brittle, thus losing effectiveness. The duration of exposure to the elements impacts the amount of UV protection needed.
7. What is the scope of the project? Do you need to protect windows with PVC film, or do you need a moisture and vapor barrier on a slab where an LDPE (Low Density Polyethylene) film is appropriate?
8. Will the film be used in a safety or security application? Safety should always come first. Is the purpose of the film to protect workers from shattering glass or to deter intruders?
9. How long will the film need to adhere to the surface? For long-term projects, additional components may need to be added to ensure the film stays securely in place.
10. Will storage and transportation affect the film? Transportation conditions may adversely affect the film. Ensure it is stored in a cool, dry place for maximum effectiveness.

Once affixed to a clean, dry surface, protective film can effectively prevent damage to that surface. While incredibly versatile, using the wrong protective film can jeopardize both your timeline and budget.

5 Common Problems with Surface Protection Film

Here are some common challenges experienced during nearly 45 years of working with tape and surface protection film.

Poor Surface Adhesion. If the film peels off too easily, multiple factors could be at play:

• The surface didn’t have proper cleanliness or was contaminated with dust or moisture.
• Using an incorrect film can lead to insufficient adhesive or too low a tack for specific climate and conditions.
• The film wasn’t uniformly stretched during installation, creating distortion and an ineffectual seal.

Debonding. If the film separates from the adhesive, it may leave a residue on the surface. Adhesive removal can be managed with a clean cloth soaked in an appropriate organic solvent such as ethanol or acetate. Caution is required during this step to avoid creating cosmetic issues on the protected surface.

Edge Lift. This issue arises when the edges of the protective film start to lift off the surface. This is especially common with composite protective films on metals, such as aluminum. Selecting the correct film makes all the difference.

The Film Cannot Be Removed. A frequent reason for this problem is the quality of the pressure-sensitive adhesive. Be cautious of manufacturers who have not perfected this specialized adhesive technology. Some simply modify ordinary adhesives, leading to unsatisfactory results.

Moreover, prolonged exposure to sunlight could also prevent the film from being easily removed. Thus, understanding the UV rating of the film and the anticipated duration of adhesion is vital.

Ghosting. One primary objective of any construction project is a seamless transition, leaving no evidence behind. When blemishes appear on intended protected surfaces, it is often due to residue from cleaning products, marking pens, or solvents previously used on the surface. These residues can be cleared with care and diluted solvents.

Our extensive range of films has successfully protected various finished surfaces, including polished or painted metals, textured surfaces, glass, and plastics.
