  • Patent number: 11718079
    Abstract: Disclosed are compositions and methods for multilayer films, which, in one embodiment may comprise a core layer comprising at least 50 wt. % of high-density polyethylene. Further, the multilayer film may include a first skin layer comprising, consisting essentially of, or consisting of low-density polyethylene, optionally linear, and at least about 80 wt. % of high-density polyethylene, as well as a second skin layer comprising either: (i) one or more low-density polyethylenes, any or all of them optionally being linear; or (ii) one or more polypropylene-based copolymers. The multilayer film may be oriented in at least one direction.

  • Patent number: 10737474
    Abstract: The invention relates to transparent multilayer biaxially oriented polyolefin films comprising a base layer and at least one outer matt covering layer, which contains at least two incompatible polymers and has a surface roughness of at least 2.0 [mu]m. The covering layer contains a polydialkyl siloxane having a viscosity of 100,000 to 500,000 mm2/s. The surface of said covering layer is pre-treated by means of corona.

  • Patent number: 10093082
    Abstract: 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 <2 ?m. The second sealable cover layer II contains propylene homopolymers and propylene copolymers II having a seal initiation temperature of 105 to 135° C.

  • Publication number: 20160114566
    Abstract: The invention relates to a biaxially oriented, multilayer polypropylene film constituted of at least one base layer and one first intermediate layer I and a first sealable cover layer I applied to said intermediate layer I, the first intermediate layer I being a soft intermediate layer and all layers of the film substantially not containing vacuoles. The film is used for producing bag packaging.

  • Publication number: 20060251840
    Abstract: The invention relates to a metallised, coextruded, multi-layered, biaxially orientated polypropylene multi-layer film comprising a base layer containing vacuoles. Said base layer containing vacuoles is covered by one or several layers and the thickness of said covering layer or layers is, in total, at least 3 ?m and the film on the outer surface of said covered layer or layers are metallised and the metallised film has a water vapour permeability of =0.5 g/m2*day at 38° C and 90 % relative air humidity and oxygen permeability of =50 cm3/m2*day*bar at 23° C. and 50% relative air humidity.
