ABSTRACT:
A multilayer film useful in chub packaging includes a heat sealable layer, an abuse layer of very low density polyethylene, a polyamide or copolyamide layer, an oxygen barrier layer, a layer comprising nylon 6 or nucleated nylon 6, and a self-weldable layer.
An alternate construction can be made without the abuse layer of very low density polyethylene, and includes an additional self-weldable layer. The film is made of a double-wound lay-flat tubular film. The film exhibits excellent impact resistant properties.
