Definitions
- Polyolefin multilayer film a process for producing this film and its use
- the invention relates to a polyolefin multilayer film with defined shrink properties from at least three layers, comprising either a) a core layer A, which acts as a base layer, and consists of at least one polyolefin and two cover layers B and C on both sides, which are the same or different, made of at least one amorphous polyolefin with one T g of 35 to 180 ° C or b) a core layer A made of at least one amorphous polyolefin with a T g of 35 to 180 ° C and two outer layers B and C, which are the same or different, made of at least one polyolefin.
- the polyolefin layers in a) and b) can also additionally contain at least one amorphous polyolefin.
- One of the cover layers B and C in a) can also be mixed with at least one polyolefin.
- the invention further relates to a method for. Production of this film and its use.
- Shrink films made of different polymers are often used as all-round labels, also called “sleeves", for plastic or glass containers, since they are easy to apply and after use of the container they are either discarded, separated or reprocessed together, i.e. recycled.
- the invention relates to a polyolefin multilayer film comprising at least three layers, comprising either a) a core layer A functioning as a base layer and comprising at least one polyolefin and two cover layers B and C on both sides, which are the same or different and consist of at least one amorphous polyolefin with a T g from 35 to 180 ° C or b) a core layer A made of at least one amorphous polyolefin with a Tg of 35 to 180 ° C and two outer layers B and C, which are the same or different, made of at least one polyolefin.
- the polyolefin layers in a) and b) can also additionally contain at least one amorphous polyolefin.
- One of the cover layers B and C in a) can also be mixed with at least one polyolefin.
- the invention further relates to a method for producing this film and its use, which creates a new, significantly improved generation of "sleeve"
- COC as a polyolefin with an amorphous character retains this property at every stage of processing, e.g. when melting, plasticizing, as a film, when stretching, and therefore does not take - like semi-crystalline materials, e.g. Polypropylene or polyester - by stretching in its crystallinity. It does not change its shrinking force and speed. COC remains stable in the non-shrinking direction during shrinkback, i.e. in contrast to other materials, there is generally no elongation or shortening transverse to the direction of shrinkage.
- the amorphous polyolefins used are either used as individual components, ie they have a uniform glass transition point T g , or as blends with different T g 's.
- the influence of adding a polyolefin to the amorphous polyolefins has already been mentioned above.
- the proportion of the amorphous polyolefin in the respective layer is in the range from 20 to 100%, preferably 60 to 95%, in particular 70 to 90%.
- the cycloolefin polymer generally contains 0.1% by weight to 100.0% by weight, preferably 0.1% by weight to 99.9% by weight, based on the total mass of the cycloolefin copolymer, of polymerized units which are each other deriving from at least one polycyclic olefin of the formulas I, II, II ', III, IV, V or VI
- cycloolefin copolymers with polymerized units derived from acyclic olefins with terminal double bonds, such as ⁇ -olefins having 2 to 20 carbon atoms, in particular ethylene or propylene, for example ethylene / norbornene and ethylene / tetracyclododecene copolymers.
- Preferred terpolymers are ethylene / norbomene / vinyl norbornene, ethylene / norbomene / norbomadiene, ethylene / tetracyclododecene, vinyl norbornene, ethylene / tetracyclododecene / vinyltetracyclododecene or ethylene / norbomene / dicyclopentadiene terpolymers.
- the use of the amorphous polymer not only improves the sealability and slippage of the film, but also increases the color adhesion when writing or printing when it is used in the cover layers.
- the cycloolefin copolymers can be prepared in a known manner at temperatures from -78 to 200 ° C. and a pressure of 0.01 to 200 bar, in the presence of one or more catalyst systems which contain at least one transition metal compound and optionally a cocatalyst and optionally a support material.
- Metallocenes in particular stereorigid metallocenes, are suitable as transition metal compounds.
- catalyst systems suitable for the preparation of the cycloolefin copolymers are e.g. described in US-A-5,008,356, EP-A-0407870, EP-A-0485893 and EP-A-0 503 422, which are incorporated by reference.
- Amorphous polyolefins are understood to mean those polyolefins which, despite an irregular arrangement of the molecular chains at room temperature, are solids. They are essentially non-crystalline and their degree of crystallinity is generally below 5%, preferably below 2%, or is 0%, determined by X-ray if fractometry.
- the heat resistance of the cycloolefin copolymers can be adjusted over a wide range.
- the glass transition temperature for cycloolefin copolymers measured in accordance with DIN EN ISO 11357-1 with the aid of a DSC, can be used as a guide for the heat resistance, as can be determined on injection moldings in accordance with ISO 75 Part 1 and Part 2.
- the cycloolefin copolymers described have glass transition temperatures in the range from 35 to 180 ° C., preferably from 50 to 170 ° C., in particular from 55 to 140 ° C.
- the temperature at which cross stretching is performed can vary. In general, it is carried out at 35 to 150 ° C, preferably 80 to 120 ° C - adapted to the respective T g 's.
- T A temperature when shrinking 10% [° C]
- T E temperature when shrinking 70% [° C]
- ⁇ T difference T E - T A [K]
