Pouch including an insulation pad (100) including two juxtaposed cellulose-based sheets (110, 112) and a cellulose-based insulation material (120). The two juxtaposed cellulose-based sheets are laminated together with the cellulose-based insulation material located therebetween. The pouch further includes transverse fold lines (134) in the insulation pad. The pouch further includes two W-shaped folds (140) in the insulation pad. The two W-shaped folds are formed by folding the insulation pad along the transverse fold lines. Portions of a first longitudinal edge (116) of the insulation pad are coupled to each other between the two W-shaped folds in the insulation pad.

A polymer-metal sandwich structure includes a first layer made of a polymer and having a first bonding surface, a second layer made of a metal and having a second bonding surface, and a third layer sandwiched between and in contact with the first and second bonding surfaces. The first layer contains or is capable of liberating anions of a first ion type at the first bonding surface, the second layer contains or is capable of liberating cations of a second ion type at the second bonding surface, and the third layer is made of a flame retardant formed of anions of the first ion type and cations of the second ion type. A method of manufacturing the polymer-metal sandwich structure is also provided.

The invention pertains to an improved branched glycolic acid polymer being obtained from polycondensation reaction of a monomer mixture comprising: (i) glycolic acid (GA); (ii) optionally, at least one hydroxyacid having only one hydroxyl group and only one carboxylic acid group different from GA [hydroxyacid (A)], wherein the molar amount of hydroxyacid (A) is of at most 5% moles with respect to the sum of moles of GA and hydroxyacid (A); (iii) at least one polyol comprising at least three hydroxyl groups and being free from carboxylic acid group [polyol (H)]; (iv) at least one alcohol comprising one or two hydroxyl groups and being free from carboxylic acid group [alcohol (AO)]; (v) optionally at least one carboxylic acid comprising one carboxylic acid group and being free from hydroxyl group [monoacid (C)]; and (vi) optionally at least one polyacid comprising at least two carboxylic acid groups and being free from hydroxyl groups [polyacid (O)], wherein the amount of polyacid (O) is such that the number of carboxylic acid groups thereof is comprised between 0.025 and 0.900% with respect to the overall number of hydroxyl groups of glycolid acid and of the hydroxyacid (A), if present.

An item may be formed from structures that include holes. Stitching may be used to form a seam that joins the structures. The stitching may be formed from a chain stitch that passes through the holes. The holes may be formed from loops of knit fabric or other holes. Leather layers, polymer layers, fabric layers, and other structures with holes may be joined using the stitching. During fabrication, a layer of material with holes may be placed on an adjustable-shape fixture having a bed of needles. The shape of the bed of nails in the adjustable-shape fixture may then be changed. After the fixture has been used to transform the shape of one or more of the structures, the structures may be placed on needles in an assembly fixture and the stitching between the structures may be formed. The item may be an electronic device cover or other item.

To provide a method for producing a multilayered container, which has a layer containing a polyester resin as a main component and a layer containing a polyamide resin as a main component and in which delamination is less likely to occur. The method for producing a multilayered container contains biaxially stretching and blow molding a preform having a polyester resin layer and a polyamide resin layer; a storage elastic modulus G′ of the polyamide resin being 5 MPa or more and less than 100 MPa; a moisture content of the polyamide resin layer being 0.5% or less; and the polyamide resin containing a xylylenediamine-based polyamide resin, 70 mol % or more of the structural units derived from diamine being derived from meta-xylylenediamine, from 80 to 97 mol % of the structural units derived from dicarboxylic acid being derived from an am-straight chain aliphatic dicarboxylic acid having from 4 to 8 carbons and from 20 to 3 mol % being derived from aromatic dicarboxylic acid.

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.

Provided herein are monolayer films, and also multilayer films comprising a core, a subskin disposed on the core, and a skin disposed on the subskin. The films may have an Elmendorf tear in MD greater than about 7.0 g/μm, a dart impact greater than about 6.0 g/μm, and a 1% secant modulus greater than about 200 MPa. In multilayer films, the core comprises a first polyethylene blend comprising an ethylene 1-hexene copolymer and a high density polyethylene composition in an amount between about 0 wt. % and about 40 wt. %. Further provided herein are bags and laminates comprising the present films.

The present invention is a resin container having a multilayer structure including a first layer that comes into contact with liquid content and a second layer that is in contact with the first layer from an outer side of the first layer. The first layer includes a cyclic olefin copolymer and a linear low-density polyethylene resin, and the second layer includes a low-density polyethylene resin.

An improved sheet for making a three-dimensional article for holding food, such as a food tray, and a method of making a three-dimensional article. The sheet comprises a substrate and a laminate film. The laminate film may comprise a ceramic film and a copolymer layer. The copolymer layer can repair any cracks that occur due in the ceramic film when the sheet is thermoformed. The food tray is considered a single material that is recyclable.
