A stretched polyethylene film for lamination, which comprises a polyethylene (A) having a weight average molecular weight (Mw) as measured by gel permeation chromatography of from 70,000 to 250,000, a proportion of fractions with a molecular weight of 10,000 or less of 8 wt % or less, and a density as measured in accordance with JIS K6922-1 (1997) of from 945 to 980 kg/m, and has at least one peak in a range of 135° C. or higher in an endothermic curve as measured by differential scanning calorimetry, the film having high recyclability and excellent in heat resistance.

Stretched polyethylene film for lamination

This invention has an object to provide: a resin composition excellent in impact resistance, flexibility, and recyclability obtained as a result of blending a specific ethylene-vinyl acetate copolymer composition with a brittle resin, a recycled resin, or a composite resin including two or more kinds of different resins mixed therein; and a molded article produced with use of the resin composition. The resin composition includes: a thermoplastic resin (A) in an amount of not less than 1 weight % and not more than 99 weight %; and an ethylene-vinyl acetate copolymer composition (B) in an amount of not less than 1 weight % and not more than 99 weight %, the ethylene-vinyl acetate copolymer composition (B) including two or more kinds of ethylene-vinyl acetate copolymers having different vinyl acetate contents, the total amount of (A) and (B) being 100 weight %.

Resin composition and molded article obtained using this resin composition

The purpose is to provide a resin composition and a film for lid material which excel in sealability and adhesiveness to plastic containers, especially containers made of polyethylene terephthalate, polylactic acid, polystyrene, or polypropylene, and are suitably usable as sealant layers of lid materials for containers. Provided is a resin composition including: an ethylene-vinyl acetate copolymer (A) by 60-95 parts by weight, the ethylene-vinyl acetate copolymer (A) having a vinyl acetate content (VA) of 3-13% by weight, and having a ratio Qw between a weight-average molecular weight (Mw) and a number-average molecular weight (Mn) of 1.5-4.5; and a tackifier resin (B) by 5-40 parts by weight, where a total amount of (A) and (B) is 100 parts by weight.

Resin composition, and film for lid materials

An object of this invention is to provide a resin composition usable as a modifier with which the brittleness of a plastic material including a plurality of resins, such as a laminate of different kinds of materials collected for recycling, can be overcome and the impact resistance and elongation at break can be enhanced. Provided is a resin composition (A) including the following components (1) and (2): (1) a composition (a1) including at least two kinds of ethylene-vinyl acetate copolymers having different vinyl acetate contents; and (2) a copolymer (a2) that is at least one copolymer selected from an ethylene-acrylic acid copolymer and an ethylene-methacrylic acid copolymer.

Resin composition, modifier, and resin composition including the modifier

To provide an adhesive excellent in adhesion to a thermoplastic resin and an ethylene/vinyl alcohol copolymer. An adhesive comprising a hydrolyzate of a resin composition containing a thermoplastic resin (A), a copolymer (B) of ethylene and a vinyl ester and/or an acrylic acid ester having a vinyl ester and/or acrylic acid ester content higher by at least 5 mol % than (A); and a modified product having (A) grafted by (B), and an adhesive resin composition comprising it.

Adhesive, adhesive resin composition and laminate comprising it

To provide a laminate excellent in the oil resistance without using a polypropylene film for the innermost layer of a packaging material. A laminate comprising at least three layers (A), (B) and (C) in this order, wherein the layer (A) is composed of a polyolefin which satisfies the following requirements (a) to (c), the layer (B) is composed of an adhesive which satisfies the following requirements (d) to (f), and the layer (C) is a substrate comprising at least one layer:
