PET film puncture resistance describes how a defined PET or PET-based construction responds to localized penetration. This technical data compares puncture force, penetration distance, energy, and failure behavior for bare, treated, coated, and adhesive-backed PET films. Results support grade or lot comparison only when the tested structure, probe setup, and conditions are identified. Sample testing remains necessary before full use.



Polyester film chemical resistance depends on the tested film construction, chemical concentration, contact temperature, exposure time, and applied stress. This technical data supports bare BOPET, surface-treated PET, and adhesive-backed protective film used on glass, metal, plastic, painted, or coated surfaces. Reference values help define a test plan, while the actual chemical, surface, dwell period, and removal behavior should be confirmed through representative sample testing before full use.

Protective film for painted sheet goods should be selected around the full processing route, not from film thickness or initial tack alone. Pre-painted steel, coated aluminum, PCM/VCM panels, roofing sheet, cladding and other finished metal can be exposed to scratches, trapped particles, edge lifting, wrinkles, adhesive transfer and visible surface marking during slitting, punching, bending, roll forming, stamping, storage and shipment. A reliable approval plan starts with the actual coating and finish, then checks application conditions, deformation severity, dwell time and removal stage. Sample testing and a production-representative trial are recommended before full use.
