What Advantages Does PETG Film Bring to Molded Fiber Tray Lamination?
PETG film is fully transparent, laminated at ~180 °C and withstands 150–180 °C after lamination. With Excellent water/oil/alcohol barriers — the transparent lamination for heated-scenario food trays.
Key Characteristics of PETG Film
Fully transparent
Fully transparent lamination showcases the tray's natural fiber texture and embossed brand logo.
Excellent all-three barriers
Water / Oil / Alcohol — all Excellent, suitable for heavy-flavor and juicy foods.
High heat resistance
Lamination at ~180 °C and withstands 150–180 °C after lamination — compatible with heated scenarios.
Color customization
Colored film to color swatch (MOQ 3000 kg).

PETG Lamination FAQ
PETG vs GPET — how to choose?
PETG is pure grade, GPET contains PBAT modifier. Both share lamination temperature (180 °C) and post-lamination resistance (150–180 °C) — choose by supply, cost and needs.
Can PETG go in the oven?
Withstands 150–180 °C after lamination — suitable for heating and short-time baking. For higher temperatures (180–220 °C) choose CPET.
What sealing film pairs with PETG?
PET sealing film; for clean full-peel opening, choose an easy-peel version.
