Appliance Cover Film
- Material: PE protective film
- Common thickness: 30–100 microns
- Standard colors: clear, blue, black & white
- Adhesion level: low to medium tack
- Typical widths: 200–1600 mm
- Main use: temporary appliance surface protection



A plastic film specified for electronics shipping should be approved against the actual contact surface, the role it plays in the ESD packaging system, and the condition expected at final removal. This guide applies to display modules, touch panels, HMI assemblies, printed overlays, coated housings, and other finished electronic products exposed to handling, storage, road, air, or sea transport. The main risks are scratching, trapped contamination, edge lift, film movement, charge generation, adhesive transfer, haze, coating disturbance, and difficult removal after extended dwell. Approval should therefore combine surface identification, packaging review, staged sample testing, transport simulation, and post-removal inspection rather than relying on one datasheet value.







Polyester film shelf life depends on construction, packaging integrity, storage history, and retained properties. This reference covers plain, treated, coated, and adhesive-coated PET protective film. Use grade-specific limits. Inspect uncertain stock against approved data and confirm it by representative sample testing before full use.

COF of PET film is used to describe the friction behavior of polyester film surfaces during starting and sliding contact. In technical data, it is typically reported as static COF and kinetic COF under a defined method such as ASTM D1894 or ISO 8295. Public PET and polyester film datasheets show that reported values vary by grade, surface, and…
