The invention relates to a peelable, transparent multilayered polyolefin film having a first cover layer I and a second sealable cover layer II. The cover layer I contains a mixture of propylene copolymers and/or propylene terpolymers and an ethylene-butylene copolymer and has a roughness of 0.1 to &#x3c;2 &#x3bc;m. The second sealable cover layer II contains propylene homopolymers and propylene copolymers II having a seal initiation temperature of 105 to 135&#xb0; C.

Transparent polyolefin film

The invention relates to the use of a multilayered, opaque, biaxially oriented polyolefin film of a vacuole-containing base layer and at least one inner cover layer comprising at least 30-95% by weight of a copolymer and/or terpolymer I having a seal initiation temperature I of 70-105&#xb0; C. and 5 to 70% by weight of an incompatible polyethylene, each of the specifications in percent by weight being based on the weight of the inner cover layer and the inner cover layer having a seal initiation temperature II of 80 to 110&#xb0; C.

Label film for deep-draw processes

The invention relates to a biaxial oriented film with a microporous layer, comprising a propylene polymer and at least one &#x3b2;-nucleating agent the microporosity of which is generated by conversion of &#x3b2;-crystalline polypropylene on drawing the film and the use thereof for the labelling of containers in blow molding. The Gurley value for the film is 10,000 to 300,000 Gurley.

Label film for blow-moulding method

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 &#x3c;2.8 wt. % and a propylene content of 97.2-98.8 wt. %, a melting point in the range 145 to 160&#xb0; 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.
