The invention relates to a multi-layer, opaque, biaxially-oriented polyolefin film with a thickness of at least 40 &#x3bc;m including a vacuole-containing base layer B and intermediate layers Z applied on both sides thereof of at least 70% by weight of a propylene homopolymer, and with a thickness of at least 3 &#x3bc;m and a covering layer D on both sides thereof of a mixture of incompatible polymers and respectively a surface roughness Rz of at least 2.5 &#x3bc;m (with a cut-off of 0.25 mm). The invention also relates to the use of this film as a wrap-around label.

Label film for all-round labels

The invention relates to a method for producing a labeled container which uses deep drawing, in which a label which is cut to size is laid in a mold and a deep-drawable thick film is heated using heating elements to a temperature at which the polymer is thermoplastically deformable and subsequently the film is drawn into a mold using a molding tool or pneumatically, so that the film is tailored to the mold and a container is molded and simultaneously the inserted label is applied, wherein the label comprises a biaxially oriented film having a microporous layer, which has an open-pored, net-like structure, which was generated during the production of the film by converting &#x3b2;-crystalline polypropylene into alpha-crystalline polypropylene during the stretching, the microporous layer facing toward the container.

Label film for deep drawing methods

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 the use of a biaxially oriented film having a porous layer, which contains propylene polymer and at least one &#x3b2;-nucleating agent and whose microporosity is generated by converting &#x3b2;-crystalline polypropylene during stretching of the film, for labeling containers during a drawing process.

The invention relates to the use of a biaxially oriented microporous film, which contains a propylene polymer and at least one &#x3b2;-nucleating agent and whose microporosity is produced by converting &#x3b2;-crystalline polypropylene when drawing the film, in order to label containers during blow molding.

Use of polypropylene films for in-mold labelling

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.

Label film for in-mould methods

The invention relates to a biaxially oriented transparent polypropylene film having a good UV barrier. The film contains, in at least one layer, nanoscalar titanium dioxide. The total content of nanoscalar titanium dioxide in the film ranges from 0.5 to 1.5% by weight with regard to the total weight of the film.

Transparent polyolefin film having a UV barrier

The invention relates to an opaque biaxially oriented film made of at least one layer that contains COC. This layer contains a cycloolefin copolymer (COC) in a concentration of 0.5 to 30 wt. % with regard to this layer and contains a polymer made from aliphatic hydroxycarboxylic acid units.

Opaque film made of polylactic acids

This invention relates to a process for metalizing polyolefin film in which at least one outermost layer of the unmetalized polyolefin film has at least about 90% cycloolefin polymer that has not been subjected to a process for increasing surface tension before metalization. The metalized films are useful as dielectrics in capacitors.

Metalized polyolefin film

A biaxially oriented polypropylene film is described. The n-heptane-insoluble content of the film has a chain isotactic index, measured by .sup.13 C-NMR spectroscopy, of at least 97%. In addition, a process for the production of the polypropylene film and the use of the film are described.

Biaxially oriented polypropylene film having increased dimensional

The invention relates to a film having more than one layer and made from cycloolefin polymers and having a base layer and at least one outer layer, the base layer being built up essentially from a cycloolefin polymer COP having a glass transition temperature Tg and the outer layer being built up essentially from a mixture of cycloolefin polymers, wherein the mixture of cycloolefin polymers comprises at least two cycloolefin polymers COP.sub.1 and COP.sub.2 whose glass transition temperatures Tg.sub.1 and Tg.sub.2 differ by at least 5.degree. C., where Tg.sub.2 -Tg.sub.1 .gtoreq.5.degree. C. and at the same time the condition Tg.sub.2 -Tg.gtoreq.5.degree. C. is fulfilled.

Biaxially oriented film made from cycloolefinic polymers, its use, and

A coating agent for plastic films which contains an intrinsically electrically conducting polymer and one or more additives which have an anti-adhesion action with respect to a metal coating to be applied to the plastic film can be used to coat plastic films. The plastic films so coated can be used to transfer a coated metal to another substrate.

Coating agent for plastic films

In a for the production of biaxially stretched films, a take-off roll 4 is arranged downstream of a draw-off roll 3 . A plastic melt is formed into an initial film by means of a slot die 1, cooled on the draw-off roll 3 and passed over the take-off roll 4 which has a predetermined surface roughness. The film is then biaxially stretched and heat-set.
