PaperSeal®

Q: What is the difference between paper-based skin trays and plastic (rPET) trays?

Both formats seal, protect and present fresh food in skin, MAP or topseal; the difference is the base material and the recycling route. A paper-based tray such as PaperSeal is a cardboard tray with a thin peelable barrier film: it contains over 80% less plastic than an all-plastic tray, the film peels off after use and the board goes with the paper. It is printable on every surface, single-piece and leak-proof, and runs on standard tray sealers with the right tooling. An rPET tray is recycled PET throughout: all plastic, but made from recycled material and recyclable again in the PET stream, with glass-clear product visibility from all sides. What you choose depends on your focus: plastic reduction, print on every surface, or visibility of the product from every angle. It can be a product-by-product decision rather than a company-wide one. GREENFLEX supplies both formats and provides counter-samples of both.

What is the difference between paper-based skin trays and plastic (rPET) trays?

Both seal, protect and present fresh food in skin, MAP or topseal. GREENFLEX supplies both formats, the paper-based trays on this page and plastic (rPET) skin trays, so we have no side to pick. The differences at a glance:

	Paper-based tray (PaperSeal)	rPET tray
Material	Cardboard tray with a thin peelable barrier film	Recycled PET, one material throughout
Plastic content	Over 80% less plastic than an all-plastic tray	All plastic, but made from recycled PET and recyclable again
After use	The film peels off the board; the board goes with the paper	The whole tray goes into the PET stream
On shelf	Printable on every surface, matte paper look	Glass-clear, the product visible from all sides
On the line	Runs skin, MAP and topseal on standard tray sealers with the right tooling; single-piece and leak-proof	Runs the same formats on the same sealers

What you choose depends on your focus: plastic reduction, print on every surface, or visibility of the product from every angle.

This can also be a product-by-product decision, not a company-wide one. Ask us for counter-samples of both and judge them on your own product and your own line.
