Abstract
A sealable film is used for the production of tear-open packages. The film, as a monofilm, in total, or as a multi-layer laminate film, produced by means of coextrusion, has at least in one layer a polymer mixture of a cycloolefin copolymer (COC) and polyolefin or an ethylene copolymer, whereby the COC portion in the polymer mixture is 10 to 80 wt.-%, the remainder polyolefin or ethylene copolymer. Packages produced from such films demonstrate balanced tear start and tear propagation properties in the crosswise and lengthwise direction of the film.
