The present invention refers to a polymeric film comprising odor barrier material and being able to pack malodorous waste.

The present invention provides a polyester film suitable for use as a sealant, which not only has high heat sealing strength, but also is less liable to adsorb various organic compounds, and has a less shrinkage in heating and high tensile strength. Further, the present invention provides a laminate comprising at least one layer of the polyester film, and a packaging bag including the same. The polyester film which is formed with a polyester resin whose main constituent is ethylene terephthalate. The film has at least one heat sealing layer. The film has a predetermined heat sealing strength, a predetermined difference in reversing heat capacity measured with a temperature modulated DSC, and a predetermined heat shrinkage. Further, the laminate comprises at least one layer of the polyester film, and the packaging bag includes the same.

A multilayer film comprising, in this order: (a) a biaxially oriented polyethylene terephthalate layer, (b) a pressure sensitive adhesive layer, (c) an elastic polyurethane dispersion, and (d) a biaxially oriented polyethylene terephthalate layer.

Layer (d) preferably has the structure A:B:A:C; where A and B preferably comprise crystalline PET and antiblocking particles and C is preferably an amorphous, heat-sealable copolyester.

A packaging structure and methods of manufacturing a packaging structure. The packaging structure, for example, an edge protector, a corner board, etc., may generally include a first ply having a first width, a second ply having a second width, and a third ply having a third width wider than the first width and the second width. The second ply may be wrapped around at least one end of the first ply, and the third ply may be wrapped around the first ply and the second ply. The third ply may overlap at a portion (e.g., an intermediate portion, an apex, etc.) of the packaging structure.

An object of the present invention is to provide a barrier film whose gas barrier properties hardly deteriorate even after a retort treatment and after a Gelboflex test. The barrier film of the present invention includes a barrier coat layer, an inorganic oxide deposition layer, and a substrate layer, in this order, wherein the barrier coat layer has a hardness of 1.10 GPa or more and 1.55 GPa or less, and a plastic deformation rate of 21.0% or more.

A polyester-based film comprising at least one layer permitting printing as a result of laser irradiation; wherein not less than 100 ppm but not greater than 3000 ppm of laser-printable metal is present in all layers of the film. The film is capable of being printed in distinct fashion by a laser, excels with respect to unevenness in thickness, and is of high transparency, while at the same time provide packaging which employs such film and on which printing has been directly carried out.

Functionalized textile materials are provided. At least a portion of a textile surface in includes a ceramic material, such as a binderless porous structured ceramic, and optionally, one or more functional layer is applied, resulting in a textile material with one or more desirable functional properties, such as hydrophilicity, hydrophobicity, flame retardancy, photocatalysis, anti-fouling, and/or deodorant properties.

A resin composition containing: a thermoplastic resin (A) that does not contain a polar group; a thermoplastic resin (B) that contains a polar group; an ethylene-vinyl alcohol copolymer (C) having an ethylene content of 20 to 60 mol %; an aliphatic carboxylic acid (D) having 3 or more carbon atoms; and an aliphatic carboxylic acid metal salt (E) that is a metal salt of the aliphatic carboxylic acid (D), wherein a metal species of (E) is at least one selected from the group consisting of elements belonging to the fourth period d-block in the long periodic table, the content of (A) is 66 to 99 wt. % with respect to the total sum of contents of the resin composition, and the content of (C) is 0.1 to 25 wt. % with respect to the total sum of the contents of the resin composition.

Described is a mono-axially oriented polyolefin film including a core or base layer containing a plurality of voids formed by a cavitating agent, wherein the film is oriented at least 4 times in the machine direction, and exhibits excellent tear resistance in the transverse direction.

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 at least 80 wt. % of high-density polyethylene, and a second skin layer comprising either: (i) one or more low-density polyethylenes; or (ii) one or more polypropylene-based copolymers. The multilayer film may be oriented in at least one direction.
