  • Patent number: 11725089
    Abstract: A bonding material is described that is well suited to bonding polymer films, such as polyester films, to other substrates. In one embodiment, for instance, the bonding material can be used to bond a polyester film to a polypropylene article. The bonding material generally comprises an adhesive agent combined with a cross-linking agent. The adhesive agent may comprise a carboxylic acid modified polypropylene homopolymer, copolymer or ionomer. In one embodiment, the adhesive agent comprises a polypropylene modified by an unsaturated dicarboxylic acid anhydride. The cross-linking agent, on the other hand, may comprise an oxazoline polymer.

  • Publication number: 20090208685
    Abstract: The presently disclosed subject matter is directed to packaging films that include semi-crystalline cyclic olefin copolymers, amorphous cyclic olefin copolymers, and/or cyclic olefin polymers present in the sealant layer and/or in the layer adjacent to the sealant layer such that the film exhibits decreased scalping of essential oils, flavor compounds, antibacterial additives, antifungal additives, and the like from products packaged using the disclosed films. More particularly, the presently disclosed films minimally scalp polar cyclic compounds from the packaged product. The presently disclosed subject matter is further directed to making and using the disclosed films.
