Coextruded PET/RPET sheet
Wellman Inc.'s (Ripon, WI) Extrusion Division introduces a coextruded polyester rollstock using 100% post-consumer recycled PET sandwiched between two layers of virgin PET.
Last month the supplier was issued a letter of nonobjection by the FDA for direct-food contact including thermoformed trays for salads fresh fruits and vegetables; containers for instant and regular coffees and teas; packaging for cereals with no surface fat content; and airline catering trays. The sheet is available in gauges from 0.01" to 0.04". Virgin PET layers require a minimal thickness of 0.001". Depending on part design and forming requirements the use of 75% or more re-cycled content can be achieved says the company.
