A laminate composite composed of at least two laminations (1, 7) and an imprint located between them (3). The lamination (7) includes at least two layers (4, 5, 6). One layer (5) includes a UV absorber to protect the imprint. This layer (5) is characterized by having a lower density than the other layers (4, 6). The other layers (4, 6) preferably have a density that is higher relative to the one layer (5) by a factor of 1.005, in particular by a factor of 1.01, preferably by a factor of 1.015.

A method for manufacturing a packaging body according to the present disclosure includes the steps of: (A) preparing a packaging material that includes an innermost layer containing a resin composition containing a polypropylene resin and a filler dispersed in the resin composition, a ratio Y/X of an average particle diameter Y μm of the filler to a thickness X μm of the innermost layer being 0.02 to 3.5; (B) producing a packaging body that has the packaging material and an oil-in-water dispersion-type content hermetically housed by the packaging material; and (C) subjecting the packaging body to a heating treatment so as to absorb oil contained in the content into the innermost layer.

The invention provides a laminated body which contains an environmentally friendly recycled material, has a lamination constitution composed of substantially a single resin type mainly composed of polyester and having a low environmental load, and has required performances such as gas barrier properties, sealability, toughness, and transparency required for a packaging material.

The laminated body is formed by laminating a polyester substrate film containing 50% by weight or more of a polyester resin recycled from PET bottles and a heat sealable resin layer in this order,

wherein the substrate film is a laminated film including an inorganic thin film layer (A) and a protective layer (a) containing a urethane resin on one surface thereof, and

the heat sealable resin layer is formed of a polyester-based resin mainly composed of ethylene terephthalate, and has a piercing strength of 10 N or more and a haze of 20% or less.

A laminate for forming a packaging bag including a substrate layer containing a crystalline polyester film, an adhesive layer, and a sealant layer containing the polyester film arranged in this order. The sealant layer has a ratio of a fracture elongation thereof to a thickness thereof which is 13%/um or less. The fracture elongation is a fracture elongation of the sealant layer as measured in a unit of 15mm width thereof in an MD direction.

Tear and heat resistant foams used in packaging, protective packaging bags and related methods are provided. The tear and heat resistant foam can include a nonwoven substrate, a polyethylene film, and a base layer of polyethylene foam joined together by applying at least one of heat or heat and pressure to the top nonwoven substrate, the polyethylene film and the polyethylene foam to heat the first surface of the top nonwoven substrate to a temperature that is above the melting point of polyethylene film but below the melting point of top nonwoven substrate. The temperature of the polyethylene film rises causing the polyethylene film to melt and bind the top nonwoven substrate to the polyethylene foam to form the heat and tear resistant packaging foam.

The invention relates to a sealant antifog composition for polyester films comprising anionic and non-ionic surfactants in a mixture of amorphous and (semi)crystalline polyesters. The invention also relates to a multi-layer film comprising a sealant layer having the above composition, to the use of said films in food packaging and to the packages obtained therefrom.

An ethylene-vinyl alcohol copolymer resin composition, including: an ethylene-vinyl alcohol copolymer (A); acetic acid and/or a salt thereof (B); an aliphatic carboxylic acid (C) other than acetic acid; and an aliphatic carboxylic acid metal salt (D), wherein a metal species of the salt (D) is at least one selected from long Periodic Table 4th-period d-block elements, and wherein respective contents of the acetic acid and/or the salt thereof (B), the acid (C), and the salt (D) satisfy the following formulae (1) and (2) on a weight basis is provided. The resin composition is excellent in impact resistance and adhesive strength even without being blended with any other resin:
0.001≤(content of (D) in terms of metal ion/content of (B) in terms of acetic acid ion)≤1.30  (1)
0.11≤(content of (D) in terms of metal ion/content of (C) in terms of carboxylic acid ion)≤100  (2).

This invention relates to a biodegradable film which is particularly suitable for the manufacture of packaging and is also characterised by high level mechanical properties.

The present invention relates to an adsorbent suitable for the adsorption of MOAH and/or MOSH compounds, the use of the adsorbent for the production of a packaging material or a container comprising the adsorbent, the process of production of the packaging material or container as well as the respective packaging material and container.

To provide a process for producing a film excellent in water vapor barrier property, tensile elongations, and transparency. A resin material containing polychlorotrifluoroethylene (PCTFE) is melted and extruded into a film from an extrusion die, the extruded product is brought into contact with a cooling roll having a surface temperature of at most 120° C. in a state such that the surface temperature of the extruded product is higher than the crystallization temperature of PCTFE to form a film web, and the film web is subjected to heat treatment at from 80 to 200° C. to obtain a film.
