摘要： The present invention relates to methods of manufacturing multi-layered polyolefin films that provide excellent adhesion to cold seal cohesive formulations. A surface of the film is discharge-treated. It has been found that when the discharge-treated surface has at least 0.3% nitrogen functional groups, it provides an excellent cold seal receptive surface. A biaxially oriented polypropylene film made according the invention may also have a second skin layer, opposite the first layer, which may be used for metallizing, laminating, or printing.

摘要： A metallized laminate film exhibiting improved moisture barrier property as well as maintaining a high bio-polymer content and degradability property is disclosed. The laminate film includes a first core layer of polylactic acid polymer and a second skin layer comprising a polyolefin metal receiving layer. The metal receiving layer or the core layer, or both, may be blended with an amount of polar-modified tie-resin to improve bonding. Alternatively, a discrete tie-resin layer may be interposed between the polyolefin metal receiving layer and the crystalline polylactic acid polymer core layer. The polyolefin metal receiving layer may be discharge-treated on the side opposite the core layer and metallized.

摘要： The present invention is directed to a multilayer film having, as its main component, a hydroxy acid polymer with improved gas barrier and optional heat sealability. The oriented film of predominately hydroxy acid polymer having controlled shrink can be produced by melting and coextruding a hydroxy acid polymer with a much thinner layer of an amorphous aromatic copolyester to form a multilayer film that is quench cooled, then biaxially stretched at a process temperature above the glass transition and below the cold crystallization temperature of the hydroxy acid polymer. A heat-setting treatment with a controlled relaxation of the film above the hydroxy acid polymer glass transition temperature and below its melt temperature may be used to control shrinkage. The films thus obtained are vacuum metallized on the aromatic copolyester surface to produce environmentally friendly packaging from predominately renewable resources having improved gas barrier properties.
