Abstract: A packaging cushion is disclosed for supporting and protecting objects during shipment. The cushion has upper and lower surfaces and one or more compartments for supporting the objects in positions so that the objects are higher than the lower surfaces of the cushions. The cushions may include upper and lower nodes which increase the separation distance between the objects when the cushions are stacked one on top of another. The cushions may be held in a stack by an outer box, or by wrapping the stack of cushions in a protective film, eliminating the need for an outer box.

Abstract: A method includes the steps of providing a tubing having an inner annular layer comprising a crosslinked polymeric material, and an outer annular layer comprising a non-crosslinked polymeric material, or a material that is crosslinked to a lesser extent than the material of the inner layer; longitudinally slitting the tubing to form a folded film; and reverse centerfolding the folded film to provide a folded film having a lateral slit edge, and a lateral folded edge opposite said lateral slit edge, such that the inner annular layer becomes an outer layer, and the outer annular layer becomes an inner layer. A bag can be made from the reverse centerfolded film, and an article such as food can be packaged in the bag.

Abstract: A method of storing a film having an active film material includes providing a carrier film and at least one strip of the active film material, positioning the at least one strip with respect to the carrier film; and rolling the at least one strip and carrier film together such that the at least one strip is isolated at least along its two major surfaces from the environment while the carrier film and the film with the active film material are in a rolled condition. The present invention also includes a roll of film including a carrier film, and at least one strip of active film material isolated from the environment.

Abstract: A shrink bag having an integral carrying handle is provided that includes an extended lip bag of a heat shrinkable thermoplastic material and having a carrying hole in the lip with a continuous fused bead around its periphery, the carrying hole being spaced sufficiently below the top of the lip such that upon heat shrinking the bag about a product sealed therein enhanced thickening along the carrying-load bearing portion of the hole periphery occurs relative to the non-load bearing portion of the hole periphery. An associated method for making the bag is also provided.

Abstract: A film of ethylene vinyl acetate having a narrow molecular weight distribution and a saran composition that is a blend of emulsion and suspension polymerized saran or a saran composition that includes emulsion polymerized saran of the type generally considered suitable for liquid coating. A laminate including the film and composition and the method for production thereof including sequentially melt extruding tubular films of ethylene vinyl acetate which is irradiated, saran and ethylene vinyl acetate and then bubble orienting the three-ply laminate. The laminate is employed for packaging and forming packages of bone-in fresh red meat.

Abstract: The multi-layer polyester/polyolefin shrink film of this invention provides a combination of shrink tension, hot seal strength, sealability, and shrink temperature range heretofore unobtainable in an oriented, monolayer polyolefin material. The preferred film has five layers in which the middle layer comprises a polyester or copolyester, two inner layers adjacent the middle layer comprise ethylene-vinyl actate copolymer, and the skin or outer layers comprise an ethylene-propylene copolymer.

Abstract: Saran blended with butyl rubber exhibits a good balance of melt extrudability and oxygen barrier properties.

Abstract: This invention is a process for making a self-welding packaging film by blending at least two ethylene polymers, one of the polymers having a melt flow substantially greater than any of the other polymers in the blend, and thereafter extruding a film from the blend. The film may be self-supporting or it may be an inner layer in a multi-ply film. Preferred ethylene polymers for the blend are the ethylene-vinyl acetate copolymers wherein one copolymer has a melt flow of less than 5.0 and the other has a melt flow greater than 28.0.

Abstract: A melt extrusion process is taught which employs a saran of the type generally considered suitable for liquid coating.

Abstract: A heat shrinkable multi-layer packaging film having a layer of a hydrolyzed ethylene-vinyl acetate copolymer. Preferably, the film is formed by coextruding the hydrolyzed ethylene-vinyl acetate copolymer layer between two other polymeric layers, at least one of which is cross-linkable, and thereafter irradiating and orienting the multi-layer structure. The resulting film is heat shrinkable and has very low oxygen permeability.
