Can GPET (PETG) film be laminated to molded fiber packaging?
Yes. GPET film offers good heat resistance and sealing performance — lamination up to 180°C and oven heating (150–180°C) after lamination — a mainstream solution balancing display and function.
Why choose GPET-laminated trays
Premium display
Smooth, even tray appearance after lamination that complements the food's natural look — ideal for premium retail and open display
Heat resistance
Lamination up to 180°C; oven-safe after lamination (150–180°C)
All-round barrier
Excellent resistance to water, oil and alcohol
Food contact compliance
EU food contact and FDA documentation available (latest test reports prevail)

FAQs
What is the difference between GPET and CPET?
GPET has oven resistance of 150–180°C. CPET withstands higher temperatures (180–220°C) for baking applications, with a misty translucent appearance.
Is GPET film food contact safe?
Yes. GPET film is supported by food contact compliance documentation; migration test results are available in the latest reports.
Should I choose GPET or CPET?
Choose CPET if your product goes into a hot oven (above 180°C). Choose GPET if heating stays within 150–180°C — the better choice in that range. Try the film selector on our homepage for a quick recommendation.
