  • Patent number: 8168290
    Abstract: The multilayer film serves as a laminate. The film is a multilayered structure that, in its base form, encompasses an intermediate layer with first and second outer layer affixed to opposing sides of the intermediate layer. The first outer layer is a semi-crystalline fluoropolymer. The intermediate layer includes a polyester and the second outer layer is an olefinic polymer. The layers are bonded together in the noted order to provide the multilayer film.

  • Publication number: 20120063704
    Abstract: A thermoplastic bag suitable for use as a liner for a garbage canister or trash receptacle may be made from a multi-layered thermoplastic web material. The multi-layer web material may include a first layer and a second layer adjacent to the first layer. Under typical conditions, the layers may tend to block or adhere together to remain in their adjacent position. However, the layers may delaminate and separate from each other when sufficient forces are applied. Delamination of the layers allows the layers to move with respect to each other when the force is applied. The delaminating of the layers absorbs energy which may increase tear and puncture resistance.
