摘要： The present invention relates to a multilayer collation shrink film, comprising at least two layers, e.g. at least three layers, wherein at least one layer (A) comprises at least (A1) a specific multimodal copolymer of ethylene and (A2) LDPE and at least one layer (B) comprises at least (B 1) recycled LDPE and (B2) a specific copolymer of ethylene. The invention further refers to a method for manufacturing this multilayer film and its use in the field of secondary packaging.

摘要： The present invention relates to a multilayer collation shrink film, comprising at least three layers, wherein core layer (B) comprises at least (B1) recycled LDPE having a strain hardening factor of from 1.5 to 5.0 when measured at 180°C, at a strain rate of 3.0 s-1 and a Hencky strain of 2.5 in an amount of at least 50 wt%, based on the total weight of the core layer (B), and (B2) a specific linear copolymer of ethylene. The invention further refers to a method for manufacturing this multilayer film and its use in the field of secondary packaging.
