Abstract
The heat-shrink film made as two layers comprises a layer of linear polyethylene (2) with copolymers of ethylene and comonomers of alpha-olefin with a density 0.87-0.94 g cm3, and a layer of propylene-ethylene-butene terpolymer (3), in a weight ratio of 75-25 %. The two-layer film is produced via a plane coextrusion head with partial reticulation of the layer (2). The film (1) is bi-orientated via a drawing process.
