The invention relates to a cover or case for goods, in particular for use as a cover or case for hobby or sports equipment. In an embodiment, the case has an inner portion, formed of expanded polypropylene (ePP) and defining a cavity for receiving at least part of the item. The case also includes an outer layer, formed of self-reinforcing polypropylene (srPP), arranged to cover an outer surface of at least part of the inner portion. In further embodiments, the cover is formed of two or more sections that may be arranged to at least partially overlap, wherein adjusting the overlap of the at least two sections changes the dimensions of an inner cavity within the cover or case. The case may be telescoping, in order to provide adjustable dimensions for a cavity within the case.

A packaged product has a product surrounded by a vacuum skin package. The vacuum skin package has a support member and an implosion-resistant thermoplastic top web. The top web conforms with both the upper surface of the product, and an uncovered portion of the upper surface of the support member. The thermoplastic top web comprises an ethylene/α-olefin copolymer in an amount of from 55 wt % to 85 wt %, based on total weight of top web, and/or a blend of ethylene/α-olefin copolymer and cyclic olefin copolymer. Also disclosed is a vacuum skin package containing the implosion-resistant top web.

The present invention relates to a biodegradable multi-layer packaging element, such as a foil or wrap, for a food product, a food packaging unit comprising such multi-layer and a method for manufacturing such biodegradable multi-layer, with the multi-layer comprising: —an inner cover layer comprising an amount of a biodegradable aliphatic polyester; —a first intermediate layer of a biodegradable material for connecting and/or sealing adjacent layers; —a functional layer comprising a vinyl alcohol polymer; —a second intermediate layer of a biodegradable material for connecting and/or sealing adjacent layers; and —an outer cover layer comprising an amount of a biodegradable aliphatic polyester.

A multilayer structure for storing hydrogen, including, from the inside, at least one sealing layer and at least one composite reinforcement layer, an innermost composite reinforcement layer being welded to an outermost adjacent sealing layer, the sealing layers being a composition predominantly of: at least one semi-crystalline polyamide thermoplastic polymer P1i, i=1 to n, n being the number of sealing layers, excluding an amide polyether block (PEBA), up to 50% by weight of impact modifier relative to the total weight of the composition, up to 1.5% by weight of plasticizer relative to the total weight of the composition, and at least one of the composite reinforcement layers of a fibrous material in the form of continuous fibers, which is impregnated with a composition predominantly of at least one semi-crystalline polyamide polymer P2j, j=1 to m, m being the number of reinforcement layers.

A tube for receiving a liquid or pasty product comprising a multilayered tube jacket, the tube jacket having one or more outer layer(s) made of polyolefin, one or more inner layer(s) made of polyolefin and a barrier layer arranged between the outer layer(s) and the inner layer(s), wherein the barrier layer consists of an ethylene-vinyl alcohol copolymer (EVOH), and wherein the ethylene-vinyl alcohol copolymer of the barrier layer has an ethylene content of <35 mol % and the thickness of the barrier layer is ≤25 μm.

Described herein is a process for preparing a flexible packaging material. The process may comprise: providing a printed first flexible substrate comprising an ink composition on a surface of a first flexible substrate, the ink composition comprising a first thermoplastic resin; depositing a further composition comprising a cross-linker, a white pigment and a second thermoplastic resin onto the printed ink composition such that the thermoplastic resin of the ink composition is cross-linked; and laminating the first flexible substrate with a second flexible substrate such that the ink composition, the further composition and the cross-linker are disposed between the first and second flexible substrates.

The present invention provides coated films and packages formed from such films. In one aspect, a partially coated film comprises (a) a film having two outer surfaces, wherein a first outer surface is provided by a film layer that comprises from 70 to 100 percent by weight of a polyolefin having a density of 0.860 to 0.965 g/cm.sup.3; and (b) a coating on the first outer surface of the film comprising polyurethane, wherein the coating covers less than 25% of the surface area of the first outer surface of the film and wherein the coated portion of the film exhibits an Elmendorf tear in at least one of the machine direction or cross direction that is at least 20% less than the Elmendorf tear of the uncoated portion in the same direction, with the Elmendorf tear being measured in accordance with ASTM D1922.

An elongate flattened thermoplastic tube has an inflation edge and an opposite edge. The tube includes spaced transverse seals that define sides of pouches. The tube includes lines of weakness that allow adjacent dunnage units to be separated. A frangible line of connection is disposed in one two superposed layers of the tube proximate to the inflation edge. This frangible connection may be broken to permit inflation of the inflatable pouches.

The present invention provides a novel multilayer structure having good gas barrier properties and good water vapor barrier properties and further having high retort resistance and a packaging material including the multilayer structure. The present invention relates to a multilayer structure including a base (X) and a layer (Y) stacked on the base (X). The layer (Y) contains an aluminum-containing compound (A) and an organic phosphorus compound (BO), and the organic phosphorus compound (BO) contains a phosphorus atom-containing functional group and at least one metal ion (Z) selected from ions of metals of Groups 1 to 12 of the periodic table, the content of the metal ion (Z) being 0.4 to 8.0 mol % relative to the content of the phosphorus atom-containing functional group.
