摘要:
The present invention relates to a multilayered film comprising a skin layer (SKL), a core layer (CL) and a sealing layer (SL), wherein the sealing layer (SL) comprises (a) 70 to 95 wt%, based on the total weight of the sealing layer (SL), of a specific metallocene-catalysed multimodal polyethylene copolymer (MMCP) and (b) 5 to 30 wt%, based on the total weight of the sealing layer (SL), of a specific elastomer, wherein components (a) and (b) add up to 100 wt%, with a beneficial combination of heat sealing and mechanical properties. The present invention furthermore relates to the use of said multilayered film as packing material, preferably for food and/or medical products.
