PE PROTECTIVE FILM have different viscosity, thickness and glue. It’s not easy to choose one prefect film for your product. When selecting ones for any project, it is critical you are able to determine how a specific product will perform in its intended application. Here are the points you need to ask (and answer!) in order to choose the right protective film:
1. Does the product have a rough or a smooth surface?
Rougher surfaces have more surface area and require a thicker adhesive.
2. What’s the surface style, be painted or have a coating?
Chemical reactions can exist between adhesives and coatings, especially the longer they are in contact with each other.
3.Is the surface area clean and dry?
Dirty application conditions will likely yield unacceptable results. Embedded materials and unnecessary debris adversely affect a protective film’s performance.
4.What type of surface needs to be protected?
Be it wood, stone, metal, glass, plastic, or ceramic; these surfaces require completely different adhesives to perform successfully.
5.Will the film be exposed to elevated temperatures?
Most rubber-based adhesives cannot handle temperatures above 150°F. Acrylic adhesives are effective at temperatures up to 350°F, and silicone adhesives up to 500°F.
6.What is the scope of the project?
Do you need to protect windows with a PVC film or do you need to provide a moisture and vapor barrier on a slab where a LDPE (Low Density Polyethylene) film is the answer .
7.Will the film be used in a safety or security application?
On any project, it’s safety first. Is the purpose of the film to protect workers from shattering glass or to deter intruders.
8.Will the film be used outdoors? If so, for how long?
The sun’s UV rays destroy adhesives over time. Protective film will not only yellow, but will become stiff and brittle, and therefore rendered ineffective. The length of time the film will be exposed to the elements will determine how much UV protection it needs.
8.How long will the film need to adhere to the surface?
If this is a long-term job, some additional component(s) may need to be added to ensure the bond of the surface to the film for the length of time you need it to hold fast.
9.Will storage and transportation affect the film?
Your crew may withstand extreme climates better than your materials! Consider their transport to the job site as well as the material’s subsequent storage so it doesn’t compromise effectiveness. Keep films and tapes in a cool, dry place.
The more specifically you can identify the requirements of your application, the closer you can come to finding that perfect film the first time around.
