摘要:
The present invention relates to a multilayer collation shrink film comprising at least the following layers: A) a layer comprising at least the following components: a1) a multimodal polymer of ethylene with at least two different comonomers selected from alpha-olefins having from 4 to 10 carbon atoms, which multimodal polymer of ethylene has a density in the range from 910 to 935 kg/m3, and a Mw/Mn of 2 to 8; a2) a multimodal terpolymer of ethylene and two alpha olefin comonomers wherein the multimodal terpolymer has a density in the range from 930 to 950 kg/m3 and a Mw/Mn of 10 to 20; and a3) LORE; B) a layer comprising at least the following components: b1) recycled LORE; and b2) a multimodal terpolymer of ethylene and two alpha olefin comonomers wherein the multimodal terpolymer has a density in the range from 930 to 950 kg/m3 and a Mw/Mn of 10 to 20. The present invention relates further to a method for manufacturing the film according to the present invention and to the use of the film for secondary packaging.
