  • Patent number: 11939112
    Abstract: 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.

  • Publication number: 20230271767
    Abstract: 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.

  • Patent number: 11503948
    Abstract: 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.

  • Publication number: 20210206148
    Abstract: Multicomponent recyclate containing polyamide components can be utilized in packaging films, saving both material and energy resources. Migration of the odorous compounds typically resulting from overprocessed polyamide materials can be minimized or eliminated by introducing odor barrier layers on both sides of the recyclate material. The resulting films have a low odor profile and can be used to package organoleptically sensitive products.
