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/cm3. The invention further relates to the use of said film for the in-mould labeling of containers made from thermoplastic polymers.

Abstract: The invention relates to the use of a biaxially oriented polyolefin film as a label film. The inventive film consists of a base layer and at least one cover layer. Said cover layer contains as the main component a copolymer or terpolymer consisting of one alkene and unsaturated carboxylic acids or the esters thereof and low amounts of an additive. The cover layer is characterized by excellent and divers adhesion to various polymer materials from which containers are formed. It is no longer necessary to apply adhesives, primers, coatings etc. in a separate step after production of the film.
