  • Patent number: 6132827
    Abstract: A multilayer industrial stretch film is provided with at least one cling layer and is formed by coextruding a film-formable polymer with a tackifier. The invention provides a multilayer film having at least two skin layers and at least one core layer in which at least one of the skin layers is derived from a mixture of the tackifier and the film-formable polymer. At least one of the core layers can include a vapor corrosion inhibitor (VCI). Beneficial results are obtained by also including a lubricating composition in at least one, if not both, skin layers when at least one of the core layers contains a VCI. The lubricant in the skin layer effectively reduces the extrusion temperature (for blown and cast films), and tends to avoid degrading or igniting the VCI.
