The present invention provides a multilayer stretch film comprising at least one core layer arranged between two exterior layers, wherein the thickness of the film is in the range of 5-40 μm, and wherein the film comprises a recycled post-consumer waste polyethylene material at a content of from 10 to 90% by weight based on the total weight of the film.

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.

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.

The present disclosure relates to a polyester resin blend, a polyester film and a preparation method of the same. The polyester resin blend is capable of providing a heat shrinkable label that is transparent and has excellent shrinkage even if it contains recycled polyethylene terephthalate as well as virgin polyethylene terephthalate. In addition, the heat shrinkable label can be reused while attached to a PET container, etc., and is expected to be useful for providing continuously usable plastics that have been recently attracting attention.

An encapsulation film, a method for manufacturing the same, an organic electronic device comprising the same, and a method for manufacturing the organic electronic device using the same are provided, where the encapsulation film allows forming a structure capable of blocking moisture or oxygen penetrating into an organic electronic device from outside and prevents generation of bright spots in the organic electronic device.

A barrier material comprising (a) at least one layer of cellulosic substrate comprising MFC, and (b) a first barrier layer arranged on at least one surface of said cellulosic substrate, is provided, as well as a method for reducing the water vapour transmission rate (WVTR) of a cellulosic substrate.

Disclosed is a packaging for a flexible secondary battery comprising a first polymer resin layer, a barrier layer formed on the first polymer resin layer to block water and gas, and a second polymer resin layer formed on the barrier layer. The thickness of the barrier layer is 30 to 999 nm. The barrier layer is multi-layered, and comprises graphene, a dispersing agent, and pyrene as a flexible linking agent, in which there is π-π conjugation (interaction) between the graphene and the pyrene. Also disclosed is a flexible secondary battery comprising the packaging.

A method of manufacturing a wrapper for an aerosol generating article includes applying an adhesive to one surface of a metal layer and attaching a first paper layer thereto, applying the adhesive to the other surface of the metal layer and attaching thereto a second paper layer different from the first paper layer, and drying the adhesive applied between the metal layer and the first paper layer and the adhesive applied between the metal layer and the second paper layer.

A film composite for film packaging, having a cover film composed of a polyolefin and a barrier layer, wherein the cover film has an imprinting, at least in part, on a side that faces the barrier layer. An equalization layer is arranged between the cover film and the barrier layer, which layer borders, at least in part, on the imprinting, wherein the equalization layer is formed from a hardened material on the basis of polyurethane.

A method of preparing a multi-layer assembly, or of protecting a surface of a multi-layer substrate from damage and/or contamination and/or debris, said method comprising the steps of: (i) providing a composite film comprising a polymeric base layer having a first and second surface and disposed on the first surface thereof a polymeric protective layer having a first surface and a second surface such that the first surface of the said base layer is in contact with the first surface of the polymeric protective layer, wherein said polymeric protective layer comprises an ethylene-based copolymer, and preferably wherein the polymeric base layer comprises a polyester derived from one or more diol(s) and one or more dicarboxylic acid(s); (ii) removing said polymeric protective layer from the first surface of said base layer; (iii) disposing on the exposed first surface of said base layer one or more functional layers to provide a multi-layer substrate, wherein the, or at least the uppermost, functional layer comprises zinc and/or tin in an amount of from about 5 to about 80 wt % of said functional layer; and (iv) disposing a polymeric protective layer comprising an ethylene-based copolymer onto the exposed surface of the, or at least the uppermost, functional layer comprising zinc and/or tin to provide a multi-layer assembly.
