DUPONT Teijin Films has developed two films for packaging convenience foods, including what is believed to be the world's first opaque heat-sealable polyester film. Mylar OL polyester film is resilient enough for seal strength, peelability, and freezer-to-oven convenience, says DuPont, making it ideal for ovenable ready meal tray lidding, salads and fresh produce packaging.

DUPONT Teijin Films has developed two films for packaging convenience foods, including what is believed to be the world's first opaque heat-sealable polyester film. Mylar OL polyester film is resilient enough for seal strength, peelability, and freezer-to-oven convenience, says DuPont, making it ideal for ovenable ready meal tray lidding, salads and fresh produce packaging. The biaxially-orientated, self-venting polyester film can be used as a single web or as part of a laminate, such as FFP Packaging's Esterpeel SR, a triple laminate film which replaces both sleeve and carton. Mylar WOL has all the benefits of Mylar OL but is the first film of its kind to have a brilliant white appearance without the need for overprinting, says DuPont. This is hoped to solve the problem of the unappetising appearance of chilled convenience foods. "Our clients want consumers to judge the quality of their product by the finished results and by its packaging rather than by the chilled contents, which can give a misleading impression," says Robert Sinclair, global packaging business manager.
