Abstract: The present disclosure provides a multilayer film. In an embodiment, the multilayer film includes a sealant layer. The sealant layer includes from (i) 50 wt % to 95 wt % ethylene copolymer having a density of at least 0.918 g/cc and (ii) from 50 wt % to 5 wt % of a 1-butene polymer having a density of at least 0.913 g/cc.

Abstract: A film having a line of weakness and a method for making a film having a line of weakness are provided. The film has a barrier layer of extruded ethylene vinyl alcohol laminated on one side to a first layer of oriented polypropylene having a score line therein. The barrier layer is laminated on its second side to a second layer of polyethylene teraphthalate having a score line therein. The score line in the oriented polypropylene layer and the score line in the polyethylene teraphthalate layer lie in a plane substantially perpendicular to a plane of the film forming the line of weakness.

Abstract: A multilayer laminate useful in the packaging of respiring food products such as swiss-type cheeses which generate or release carbon dioxide gas during storage and wherein said multilayer laminate allows for the egress of said gas while minimizing the ingress of oxygen. The multilayer laminate comprises at least one layer of a low gauge polyamide such as poly (-caprolactam).

Abstract: The present invention relates to a film structure and a method of manufacturing the same. More specifically, the film structure may include a barrier material made from EVOH, nylon or other thermally sensitive barrier material encapsulated by a first adhesive material. The barrier material and the first adhesive material form a barrier layer and a first set of adhesive layers when coextruded. The barrier layer and the first set of adhesive layers may be coextruded at the same or a similar temperature to form a first extrudate. The extrudate may be encapsulated by or otherwise coextruded with a second adhesive material to form a second extrudate at a higher temperature than the first extrudate that then may be formed into a flat sheet via a die. The first set of adhesive layers protects the barrier layer from high temperatures and long residence times related to the coextrusion/lamination process that may degrade the barrier layer.

Abstract: The presently preferred embodiments relate to film structures that are exposed to focused energy to provide a score line on an internal layer of the film structure, or on both an internal layer of a film structure and an outer layer of the film structure. In addition, the present invention relates to a package that may be torn along the score line. More specifically, the package may have a score line provided on an internal layer of barrier material, such as ethylene vinyl alcohol copolymer, polyvinylidene chloride copolymer, nylon, or any other laser scorable barrier material. The score line in an internal layer and/or in the surface of the film may allow the package to be opened using tearing forces, thereby exposing a product within the package and allowing a user of the package to gain access to product that may be contained therein.

Abstract: The present invention relates to a flexible pouch that is sealed on the sides to provide a space therein for a product. On one end of the pouch may be a recloseable feature. A patterned score line may be provided on an end of the pouch for removing a sheath disposed over the recloseable feature thereby exposing the recloseable feature. The pouch may be utilized for the storage of food products, such as cheese.
