  • Publication number: 20230174691
    Abstract: Methods of making recyclable heavy-gauge films are provided. The methods of the present disclosure involve bonding the inner layers of a coextruded blown film together such that the film is sufficiently thick enough for it to be oriented in the MDO section using the typical 5:1 orientation ratio and result in a film with twice the gauge typically made by the MDO process (while maintaining acceptable stiffness and dimensional rigidity). Recyclable heavy-gauge films formed by the methods are also provided.

  • Publication number: 20230037446
    Abstract: Recyclable films and methods of making the recyclable films are provided. The recyclable films include a low melt index blend of super hexene LLDPE and bimodal HDPE and an anti-stick additive having a melting point of at least about 115° C. The recyclable films have a heat resistant coating on the film surface that prevents the film from softening and sticking to heat seal jaws during the production process. The recyclable films also have improved tear strength and melt strength such that instances of tears or break offs during the machine direction orientation portion of the production process are significantly reduced or eliminated.

  • Patent number: 7862887
    Abstract: The present invention provides a multilayer sealable film having a sealable outer layer, a first heat resistant layer, a core layer, and a second heat resistant layer. In a preferred embodiment of the present invention, the core layer is positioned between the two heat resistant layers. The sealable layer is positioned such that one of the heat resistant layers is located between the seal layer and the core layers.
