A tray composite comprises a polymeric based liner including an exterior surface layer, an interior surface layer, and a fiber based component removably affixed to the interior surface layer of the polymeric based liner. A release agent is located between the polymeric based liner and the fiber based component. The polymeric based liner and the fiber based component are manually separable after they have been removably affixed together.

Tray composite and package

An ovenable tray composite that includes a polymeric based liner and a fiber based component. The liner has an exterior surface layer and an interior surface layer comprising a polypropylene. The polypropylene has a Melt Index of about 0.2 grams/10 minutes to about 2 grams/10 minutes. The interior surface layer of the polymeric based liner is removably affixed to the interior surface of the fiber based component, and where the polymeric based liner and the fiber based component are manually separable.

Ovenable tray composite and package

A tray composite comprises a polymeric based liner including an exterior surface layer, an interior surface layer, and a formed base removably affixed to the interior surface layer of the polymeric based liner. A formed base is removably affixed to the interior surface layer of the polymeric based liner. The polymeric based liner and the formed base are manually separable after they have been removably affixed together by a first portion of the interior surface layer remaining affixed to the formed base and a second portion of the interior surface layer separating from the first portion of the interior surface layer.

Tray composite, package and method

An ovenable tray composite comprises a polymeric based liner and a fiber based component. The polymeric based liner incorporates polyolefin materials for performance in both adhesion (during use) and separation (for disposal) from the fiber based component, as well as high temperature resistant polymers that allow for the entire tray composite to be ovenable. Packages made from the lined trays described herein can be used for packaging food items intended to be heated for cooking or reheating the contents.

Ovenable package

The present invention is directed to a peel-open package having a first film comprising an exterior sealant layer comprising a polyolefin polymer resin and a fatty acid or a fatty acid derivative, and a second film comprising an exterior layer comprising paper or a nonwoven material. The paper or nonwoven material is adhered to the sealant layer of the first film to form a peelable interface therebetween and to enclose a product, to accordance with the present invention, the polyolefin sealant layer of the first film is heat sealed directly to the paper or nonwoven material of the second film to form a peelable seal which can be readily peeled without substantial release of free fibers form the paper or nonwoven material.
