  • Publication number: 20140113142
    Abstract: A coextruded multilayer structure which can be oriented and a process therefor are disclosed in which the structure comprises a poly(hydroxyalkanoic acid) polymer (PHA) composition layer, a tie layer, and a sealant layer and the process comprises, consists essentially of, or consists of coextruding a PHA composition, a tie layer composition, and a sealant layer composition to produce a tubular multiplayer structure; cooling the multilayer film structure in a first bubble to produce a tubular multilayer structure; orienting the tubular multilayer structure under heating in a second bubble to produce an oriented tubular multilayer structure; and relaxing the oriented tubular multilayer structure under heating in a third bubble. The structure can be used to produce an article such as a packaging article.

  • Patent number: 8563057
    Abstract: The present invention proposes a smokable planar or hose-type food casing or food casing film for food packagings, such as, e.g., sausage casings, shrink bags or the like on polymer basis, which is for the first time manufactured in the jet-blasting process from a homogeneous molten plastic material consisting of a plastic mixture consisting of at least of PA (polyamide) with PVAL (polyvinyl alcohol) and PEBAX (polyether block amide). The food casing or food casing film has a water vapor permeability that is at least 1 kg/m2 within 24 h. Its oxygen permeability at a film thickness of 30 ?m is less than 2.1 cm3/m2 within 24 h. Moreover the present invention for the first time proposes a method for manufacturing it.

  • Publication number: 20100034999
    Abstract: The present invention proposes for the first time a two-dimensional or tubular food casing or film with an at least seven-layered laminated structure, which has an EVOH layer as an oxygen barrier and in which the outer layer is formed by a high-temperature-resistant material such as PET, which apart from outstanding appearance-related properties also makes much higher further processing speeds (numbers of cycles) possible than previously known.
