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.
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.
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…
Plastic films for flooring industry applications should be selected around the actual finish and process stage, not simply because a surface is called hard flooring. Laminate, embossed SPC or LVT, ceramic tile, and sealed stone can react differently to temporary adhesive contact. This solution covers production, handling, transport, installation, and planned removal. Key risks include scratches, trapped contamination, edge lift, film movement, adhesive transfer, haze, and surface change. Selection should consider texture, coating condition, dwell time, environment, traffic, removal timing, and actual trial results.
