<p>A multilayer heat-sealable chlorine-free film of relatively low modulus, high interlaminar strength and low noise upon flexing is provided. The film comprises an odour barrier layer of polyester resin and at least one heat-sealable skin layer, preferably two such skin layers on opposite sides of said odour barrier layer, composed of a homopolymer of ethylene or a copolymer of ethylene and an alpha-olefin or an ester-containing monomer. In a preferred embodiment, the odour barrier layer is formed of polyethylene terephthalate and adhesive tie layers are interposed between the odour barrier layer and the skin layers, resulting in a multilayer film of five layers. Pouches formed of such multilayer films are also disclosed. <IMAGE></p> |
