Abstract: A mold assembly for making a molded foam article generally includes a housing having an internal cavity and an opening into the cavity, a movable support member movable between an inner position and an outer position, an object supported by the support member and having a three-dimensional shape, and a closure. A method for making a molded foam article generally includes moving the support member to the outer position, positioning a film web over the object to form a substantially convex envelopment, moving the support member to the inner position while maintaining the film web in contact with the object to reconfigure the substantially convex film envelopment into a partially concave film envelopment, and dispensing a predetermined amount of a foamable composition into the hollow space provided by the concave envelopment.

Abstract: An L-seal patch bag has an open top, a bottom seal, a seal along a first side edge, and a patch covering a seamless second side edge. The bag is preferably made by adhering, at intervals and across a continuous flat film, a plurality of discrete film patches. Each of the patches covers a centerline running the length of the elongate flat film. The resulting laminated article is then folded along its length, preferably at the centerline, making a first seal by sealing the elongate flat film to itself by sealing along a first (open, non-seamless) side edge of the elongate flat film. A second seal is then made by sealing across an entirety of the folded, laminated article, which is thereafter cut across below the second seal, whereby an L-seal patch bag is produced. Analogous processes can be used to produce a side-seal patch bag or a backseamed patch bag.

Abstract: In order to reduce splitting in a perforated, heat shrinkable, thermoplastic bags made from seamless tubing, rather than employ needle punched perforations, it has been discovered that slits cut by a knife blade will surprisingly reduce the splitting when a product, such as a meat product, is cooked within the bag.

Abstract: Disclosed is a multiple-layer cook-in film from which packages such as bags or casings can be made. The films have a first food contact layer that bindingly adheres during cook-in to a contained meat product. The first layer comprises a polyamide composition, which is preferably (I) a polyamide or (II) a blend of a polyamide and (i) polyethylene, or a blend of a polyamide and (ii) a copolymer of an alpha-olefin having the formula RHC.dbd.CH.sub.2 wherein R is H or C.sub.1 to C.sub.8 alkyl and an alpha,beta-ethylenically unsaturated carboxylic acid.

Abstract: A pasteurizable and/or cook-in shrink film is provided with good interlaminar adhesion and good orientability, and characterized by the presence of ethylene alkyl acrylate copolymer in shrink and abuse layers, in adhesive layers, or both. An associated method for making the film is also provided that includes coextrusion of the multilayer film, optional irradiation, and orientation.

Abstract: Disclosed is a multi-layer heat-shrinkable (oriented) film having a barrier layer of polyvinylidene chloride copolymer and having an outer layer of polyamide. The polyamide layer is directly adhered to the barrier layer. Also disclosed is a method to make the film and barrier bags made therefrom.

Abstract: A pasteurizable and/or cook-in shrink film is provided that includes a first or sealing layer of a nonlipophillic polymeric material having a softening point greater than that of the following shrink layer; a second or shrink controlling layer, melt bonded to the first layer, of an ethylene homopolymer or copolymer; a third or adhesive layer, melt bonded to the second layer, of a chemically modified polyethylene being irradiatively cross-linkable and having functional groups with a relatively strong affinity for the following barrier layer; a fourth or barrier layer, melt bonded to the third layer, of a hydrolyzed ethylene-vinyl acetate copolymer; a fifth or adhesive layer as in said third layer, melt bonded to the fourth layer; and a sixth or abuse layer, melt bonded to the fifth layer. An associated method for making the film is also provided that includes full coextrusion and selective irradiation and orientation.
