Linear low density polyethylene is used in multiple layer, molecularly oriented films. Novel blends of linear low density polyethylene with ethylene vinyl acetate copolymer are disclosed, and used in molecularly oriented multiple layer films. Bags made from the multiple layer films are especially useful for shrink packaging, and particularly for shrink packaging of meats having large cavities.
