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.
Clear shipping film for amplifier control panels helps limit scratches, scuffs, trapped dust, fingerprints, and packaging contact marks on display windows, printed overlays, painted faceplates, and plastic control areas during assembly, storage, and transport. The correct film is not selected by transparency alone. It must provide enough surface contact to remain stable without creating excessive removal force after the planned protection period. Surface type, coating condition, panel geometry, packaging pressure, temperature, humidity, transport distance, and the intended removal method should all be evaluated on an actual panel before full use.
The COF of PET film describes resistance when a defined surface starts and continues sliding against another surface. This reference applies to uncoated, coated, treated and PET-based protective film used in unwinding, slitting, laminating and die cutting. Each result must be read with its tested sides, method, load and conditioning history. Equipment compatibility, adhesive behavior and removal performance still require sample testing on the actual material and process.
