  • Patent number: 11752743
    Abstract: Multilayer film comprising at least a skin layer, a core layer and an inner layer, whereby the inner layer comprises a single site catalyst derived (SSC) random propylene ethylene copolymer having—a melting temperature (Tm) from 120° C. to 144° C., —a content of units derived from ethylene in an amount of 1.5 to 6.0 wt.-%, —the melting temperature (Tm) fulfilling the following equation Tm<156° C.?[5.2×C2 content in wt.-%]° C. wherein C2 content stands for the content of units derived from ethylene; and —a xylene cold soluble content (ISO 16152, 1st ED, 2005 Jul. 1; 25° C.) of preferably below 30 wt.-% wherein the multilayer film is free of phthalic acid esters as well as decomposition products thereof.
