METHOD FOR MANUFACTURING PACKAGING BODY, FILM FOR PACKAGING MATERIAL, AND LAMINATED FILM AND PACKAGING MATERIAL COMPRISING THE SAME

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.

Inverted Tabbed Induction Liner
20220410545 · 2022-12-29 ·

Various forms of tabbed sealing members are described along with the laminates from which the sealing members are formed. In some forms, the tabbed sealing members may be considered inverted tabbed sealing members for induction sealing as the induction heating layer is provided in the upper laminate instead of the lower laminate. In this regard, the induction heating layer is positioned further from the heat seal, contrary to conventional tabbed sealing members.

LAMINATED BODY

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.

AQUEOUS DISPERSION AND LAMINATE

An object of the present invention is to provide an aqueous dispersion with which a coating film having small dynamic frictional resistance can be formed immediately after coating. The present invention includes an aqueous dispersion containing a polyolefin (A), as unsaturated carboxylic acid polymer (B), an amide-based wax (C), and water.

PTP blister sheet, and PTP blister pack formed from same

To provide a PTP blister sheet exhibiting a high adsorption effect over prolonged periods, and a PTP blister pack formed from it. A PTP blister sheet having at least a gas barrier layer and an odor adsorption layer, wherein the odor adsorption layer comprises a heat-sealable resin containing an odor adsorption agent, and the odor adsorption agent is formed by a chemical adsorption agent supported on an inorganic porous body, and a PTP blister pack formed from it.

Polyethylene based laminated film structure with barrier properties

Laminated film structure including at least one first film having a thin ceramic or metal coating, being laminated to a second film and whereby the laminated film structure is based on polyethylene only, i.e. polymers other than polyethylene are substantially absent and whereby the laminated film structure has good barrier properties.

11535018 · 2022-12-27 · ·

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.

Bag-in-box film for packaging refrigerated liquids
11535011 · 2022-12-27 · ·

Multi-layer films for making bags for containing flowable materials, in particular to large bags for dairy products. The multi-layer films have an outer and an inner sealant layer and a core layer and optionally, an interposed layer positioned between the outer sealant layer and the core layer and between the core layer and the inner sealant layer. The outer and inner sealant layers contain an ethylene/α-olefin interpolymer composition and the intermediate layer optionally contains this interpolymer composition.

Magnetic reseal
11535440 · 2022-12-27 · ·

The invention is directed to a polymeric film web, a carrier film, and a magnetic member. The carrier film comprises an inner polyethylene terephthalate layer and an outer plastomer layer. The magnetic member and the carrier film are layered onto the polymeric film web to form a closure member. The outer plastomer layer is adjacent the magnetic member and the carrier film extends beyond an upper edge and/or a lower edge of the magnetic member. The closure is heat sealed such that the seal at the interface of the first carrier film and the second carrier film is a peelable seal, the seal at the interface of the first film web and the first carrier film is a permanent seal, and the seal at the interface of the second film web and the second carrier film is a permanent seal.

COMPOSTABLE LID FOR SEALING A BEVERAGE CAPSULE OR A BEVERAGE PAD AND CAPSULES AND PADS SEALED THEREWITH

This invention relates a compostable lid for sealing a beverage capsule or a beverage pad wherein the lid comprises a natural-fiber based support obtainable by: (i) providing a first fibrous base sheet comprising natural fiber material sensitive to a gelatinizing agent; (ii) treating the first base sheet with a gelatinizing agent to give a treated first fibrous base sheet comprising gelatinized material; (iii) providing a second fibrous base sheet; (iv) contacting the treated first fibrous base sheet and the second base sheet with each other; (v) causing at least partial migration of the gelatinized material from the treated first fibrous base sheet into the second fibrous base sheet to give a multilayer product; and (vi) neutralizing and/or washing the product thus obtained and then drying it.
