Abstract
The invention relates to a biaxially-oriented opaque polypropylene multi-layer film, made from a base layer, at least one first intermediate layer arranged thereon and a first surface layer arranged on the first intermediate layer. The first intermediate layer has essentially no vacuoles. The first surface layer comprises at least 80 wt. % of a propylene/ethylene copolymer with an ethylene content of 1.2 to <2.8 wt. % and a propylene content of 97.2-98.8 wt. %, a melting point in the range 145 to 160° C. and a fusion enthalpy of 80 to 110 J/g. The base layer comprises vacuoles and has a density in the range 0.35 to 0.6 g/cm. The invention further relates to the use of said film for the in-mould labeling of containers made from thermoplastic polymers.
