Food packaging featuring high-strength permanent seals—some with peelable and even resealable functionality—provides effective barriers that protect food by keeping harmful elements out. However, traditional multilayer food contact lidding requires a two-layer tray consisting of both polyethylene (PE) and polyethylene terephthalate (PET), which can increase costs and hinder recycling efforts. Eastman Eastobond™ copolyester offers a better solution. Used as a universal sealant layer in high-, medium-, or low-barrier lidding films, it allows retailers and brands to switch to recyclable monolayer APET trays. Enabling the use of fully recyclable mono-PET trays, can reduce the environmental impact of food trays and enhances clarity without reduced performance.


  • BPA Free
  • Cost savings from eliminating tray liner
  • Does not require additional adhesives
  • Enables food tray recyclability
  • Excellent adhesion to monolayer PET
  • Not a material of concern
  • Polyolefin replacement
