The invention relates to a transparent, single or multi-layer oriented polyolefin film which consists of at least one layer containing a sheet silicate with an irregular surface structure and no metal oxide coating.

Transparent biaxially oriented polyolefin film

The application relates to a device for adjusting the gap of a die arrangement using a thermopin, which is connected to the die lip ( ) without any play by means of a clamp-type socket ( ), where the clamp-type socket ( ) engages on the one had in a lip nose ( ) and on the other hand in a groove ( ) of the thermopin ( ), where the lip nose ( ) is an integral part of the die lip ( ) and the clamp-type socket ( ) has a bore ( ), and the thermopin ( ) has a bore ( ) and a fixing means is passed through the bores ( ) and ( ).

Device for adjusting a gap

The present invention relates to a method for guiding a flat web of material ( ) in which the web of material ( ) runs in an arrangement of rotating rollers at a web speed v . The web of material is guided in its peripheral region via a spreader roll ( ) which produces a tensile stress in the transverse direction, i.e. crosswise relative to the machine direction of the web of material ( ), wherein this tension in the transverse direction is controlled by means of closed-loop control of the circumferential speed v of the spreader roll ( ) and/or by open-loop control of the cant angle &agr; and/or of the wrap angle &bgr; between the surface of the spreader roll ( ) and the web of material ( ) and wherein the circumferential speed v is greater than the web speed v .

Method and device for guiding a web of material

A biaxially oriented polyolefin film having more than one layer and made from a base layer and from at least one outer layer. The base layer include a fatty amide and the outer layer include at least 80% by weight of a linear olefin polymer. The film is suitable, for example, for producing a film laminate by melt extrusion of a polyethylene layer.

Polyolefin film, its use, and process for its production

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

Oriented multilayer polyolefin film which is heat-sealable on both sides, its use, and process for its production. An oriented multilayer polyolefin film which is heat-sealable on both sides and is printable, made from at least one base layer and, on both sides, heat-sealable outer layers, which film contains a hydrocarbon resin. Both outer layers contain silicone oil and at least one surface of the film is surface-treated.
