Disclosed are compositions and methods for multilayer films, which, in one embodiment may comprise a core layer comprising at least 50 wt. % of high-density polyethylene. Further, the multilayer film may include a first skin layer comprising, consisting essentially of, or consisting of low-density polyethylene, optionally linear, and at least about 80 wt. % of high-density polyethylene, as well as a second skin layer comprising either: (i) one or more low-density polyethylenes, any or all of them optionally being linear; or (ii) one or more polypropylene-based copolymers. The multilayer film may be oriented in at least one direction.

A heat sealing product suitable for seating one or more individual containers, said heat sealing product comprising: (i) a plurality of individual heat seals set out in a configuration substantially corresponding to the shape and configuration of the container(s) to be sealed, the size and shape of the individual heat seals corresponding substantially to the size and shape of the tops of the individual container(s) to be sealed; (ii) a peelable support film layer coated on one side with a low tack adhesive, the low tack adhesive serving to hold the individual heat seals in place on the support film layer in the desired configuration prior to the sealing process; (iii) alignment points in the sealing product adapted to enable the heat sealing product and therefore the individual heat seals of the heat sealing product to be aligned substantially exactly with respect to the individual containers to be sealed.

An exterior material for an electrical storage device has a laminate including at least a base material layer, a barrier layer, and a thermosetting resin layer in this order, the barrier layer including an aluminum alloy foil that satisfies a composition of Si: 0.5 mass % or less, Fe: 0.2-2.0 mass % inclusive, and Mg: 0.1-5.0 mass % inclusive.

The presently disclosed subject matter is generally directed to a packaging film constructed from water-dispersible and/or biodegradable compositions. Particularly, the disclosed film comprises a first layer constructed from one or more water-dispersible materials, such as water-dispersible paper. The film further comprises a second layer constructed from one or more biodegradable materials, such as poly(hydroxyalkanoate). The first and second layers can be constructed to form a packaging material used to enclose a wide variety of products, including liquids and moisture-sensitive solids. Advantageously, the disclosed film (and associated packaging materials) are dissolvable in water and/or biodegrade when exposed to landfill conditions and/or water.

The present disclosure provides a barrier laminate (F) comprising: a) at least one polyolefin core layer (X); b) at least one barrier layer (Y) joined to both the sides of the at least one polyolefin core layer (X); and c) at least one polyolefin layer (Z) adjacent to the at least one barrier layer (Y), wherein the at least one barrier layer is a polyvinyl alcohol (PVOH) coating layer on one side of the at least one polyolefin core layer (X) and has a coating thickness in the range of 0.1 gsm-1.5 gsm. The present disclosure also provides a process for preparing the barrier laminate.

A single-layer or multilayer film formed from one or more polymeric materials has CIE colour values a* and b* such that −7≤a*≤0, −15≤b*≤0 and an optical transmission T such that 60%≤T≤95%. The inventive, transparent films provide discoloration compensation that alleviates yellowing caused by UV light.

Embodiments of the invention provide a storage container including a roof and two opposing side walls. At least one of the roof and the two side walls comprises a panel member including an inner skin, an outer skin, and a core between the inner skin and the outer skin. The panel member also including an inner skin trailing edge extending beyond the core and the outer skin and an outer skin leading edge, opposite the inner skin trailing edge, extending beyond the core and the inner skin. A viscoelastic tape is provided along the trailing edge and leading edge to maintain the position of the panel. Multiple panels can be joined with an adhesive material, with the viscoelastic tape maintaining the connection between the panels while the adhesive material sets and preventing the adhesive material from exiting past the trailing and leading edges.

Composite film (1) for closing a container (10) by sealing the composite film (1) against a circumferential sealing surface (11) of the container (10) or of a cap ring (12) to be connected to the container (10). The composite film (1) comprises an outer support layer (30) made of a metal film and an inner multilayer membrane (20) laminated to the outer support layer (30) using a bonding layer (28). The membrane (20) has a consecutive layer structure from the outside to the inside consisting of a backbone layer (21) made of polypropylene, an intermediate layer (23) made of a partially crystalline polyamide and a cohesively breakable peeling layer (25) made of polypropylene, polyethylene and talc, wherein between the intermediate layer (23) and the backbone layer (21) as well as between the intermediate layer (23) and the peeling layer (25) there is arranged a tie layer (22, 24) made of a maleic acid anhydride grafted polypropylene. The membrane has further an innermost sealing layer (26) made of a random copolymer comprising monomers of propylene, ethylene and butylene, wherein the random copolymer is grafted with maleic acid anhydride. The softening point of the sealing layer (26) lies at least between 15 and 25° C. lower than that of the tie layers (22, 24). A use and a method of producing said composite film (1) are also disclosed.

The invention relates to a dark thermoplastic polymer composition, which when formed into a film has an ultra-low heat buildup, is visibly opaque, and has a high NIR transmission. The dye system involves two or more IR transparent dyes that combine to produce a color having an L value of less than 40, preferably less than 30, and a heat buildup of less than 50° F., preferably less than 45° F. In one embodiment, the composition is jet black. The composition may be a free-standing film, or a capstock used over a substrate, preferably a white substrate.

The disclosure provides compositions adapted for oral use and, in particular, multi-compartment oral pouched products including such compositions. Some aspects of the disclosure relate to oral pouched products including a composition adapted for oral use within a porous pouch. In particular, the porous pouch may include two or more compartments, each compartment having a content of the composition contained therein. The composition within each compartment can be different such that the composition within each compartment provides a different functional or sensory experience, such as through use of a different flavoring agent, a different active ingredient, or both a different flavoring agent and a different active ingredient.
