  • Publication number: 20220032592
    Abstract: The invention relates to flexible multilayer films comprising a first polymer layer (A), a second polymer layer (B), and a central polymer layer (C), wherein the central polymer layer (C) is situated between the first polymer layer (A) and the second polymer layer (B), and wherein the central polymer layer (C) comprises at least one UV absorber and at least one colorant that, in combination, absorb light in the 175 nm to 525 nm wavelength range. The multilayer film is suitable for producing medical bags having UV and light protection.

  • Patent number: 7799436
    Abstract: The invention relates to a multilayered biaxially oriented polyolefin film in the form of a release film in a laminate which is coated on an outer surface thereof with a cold seal adhesive. The release film comprises a base layer and at least one outer layer. At least one layer of the release film contains wax having an average molecular weight Mn of 200-3000. The invention also relates to a method for producing the film and the use thereof.

  • Patent number: 7144542
    Abstract: The invention relates to the use of a biaxially oriented polyolefin film as a label film. The inventive film consists of a base layer and at least one cover layer. Said cover layer contains as the main component a copolymer or terpolymer consisting of one alkene and unsaturated carboxylic acids or the esters thereof and low amounts of an additive. The cover layer is characterized by excellent and divers adhesion to various polymer materials from which containers are formed. It is no longer necessary to apply adhesives, primers, coatings etc. in a separate step after production of the film.

  • Patent number: 7052774
    Abstract: The invention relates to a biaxially oriented polypropylene multilayer film, which comprises at least one base layer (B), an intermediate layer (I) and a top layer (I), and which contains anti-fog additives. The anti-fog additive is only added to the intermediate layer (I) in a quantity ranging from 0.5 to 8 wt. % with regard to the weight of the intermediate layer, and the film contains a maximum of 0.5 to <1 wt. % of anti-fog additives with regard to the total weight of the film. The film is suited for packaging moist goods.

  • Patent number: 7011882
    Abstract: The invention relates to a multi-layered biaxially orientated polyolefin film comprising a base layer and at least one protective coating. Said protective coating contains, as the main component, one copolymer or terpolymer I, which seals against PVDC and acrylate lacquers and coatings and consists of an olefin and unsaturated carboxylate acids or the esters thereof, and small quantities of wax. The film is provided on one side with a PVDC or acrylate coating so that it can be used as roll-wrap packaging.

  • Patent number: 6844079
    Abstract: A multilayer biaxially oriented, polyolefin film consisting of a base layer, at least one first intermediate layer and a first cover layer that is applied to said intermediate layer. The first intermediate layer is made of a terpolymer consisting of three different monomers (a), (b) and (c): whereby (a) is an olefin, (b) is an unsaturated carboxylic acid or esters thereof, and (c) is an unsaturated carboxylic acid or carboxylic acid ester, which is different from (b), or is a carboxylic acid anhydride. In addition, the first cover layer contains a copolymer, and a top layer comprising a copolymer of an olefin, and an unsaturated carboxylic acid or esters thereof, and the first cover layer additionally contains an additive.
