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/a-olefin interpolymer composition and the intermediate layer optionally contains this interpolymer composition.

Hybrid fibrous composite materials incorporating at least two different fabric components and a multicomponent adhesive system for adhering the fabric components together. The adhesive system enhances the bond strength between the fabric components, which would otherwise easily delaminate from each other and peel apart. The components of the adhesive system bond strongly to each other as well as to the fabric elements.

A film structure includes a first outer layer system, a second outer layer system, and a core layer system. The first outer layer system includes at least one layer formed of a starch polymer thermoplastic bioresin. The second outer layer system includes at least one layer formed of a starch polymer thermoplastic bioresin. The core layer system includes at least one layer formed of a modified Polyvinyl Alcohol (PVOH). The first outer layer system, the second outer layer system, and the core layer system are compostable.

The present invention relates to a flexible packaging comprising a base layer and a film layer at least partially releasably affixed to the base layer via a pressure sensitive adhesive layer. The pressure sensitive adhesive layer comprises at least one adhesive zone and at least one adhesive-free zone extending continuously in a machine direction. The film layer is scored to form at least one pull tab which is disposed within the at least one adhesive-free zone and the base layer is scored to form at least one cavity which is disposed adjacent the at least one adhesive-free zone.

A plastic film composite for film packaging with an oriented outer film and a sealing film which differs from the outer film, both of which outer film and sealing film are either polyethylene-based or polypropylene-based. The outer film and the sealing film are connected by a polyolefin-based extrusion lamination comprising at least one layer. A film packaging comprising the plastic film lamination and a method for the production of packaging containers uses the plastic film composite.

Provided is a gas barrier packaging material including a base and a cured resin layer, the base having a surface constituted of an inorganic substance. The cured resin layer is a cured product of an epoxy resin composition including an epoxy resin, an epoxy resin curing agent containing an amine-based curing agent, and an acidic compound, and a ratio (basic nitrogen/acid groups) of a molar equivalent of basic nitrogen in the epoxy resin composition to a molar equivalent of acid groups derived from the acidic compound is from 0.60 to 20.

The disclosure provides ethylene/α-olefin copolymer based co-extruded, multi-layer films, including barrier films and non-barrier films, and articles of manufacture that include the films, such as flexible bags and containers for flowable materials. The films and articles that include the films have improved flex-crak resistance and toughness. The films and articles that include the films have good barrier properties as the barrier films include a core layer of ethylene-vinyl alcohol (EVOH) copolymer having a high ethylene content. The low amount of EVOH copolymer in the total film that is needed to achieve the flex-crack resistance, toughness, and good barrier properties, further allow for the recycling of the films and articles of manufacture.

A food package having a heat-sealed cover composed of a lower plastic film and an upper plastic film which is distinct and separate from the lower plastic film is disclosed. The upper and lower films are collapsible, i.e., they can be creased and crumpled into a ball without effort or folded as a tissue paper. The lower film and upper film are heat-sealed to each other at respective perimeter edges to define a closed, watertight internal housing filled with a modified atmosphere. A tray, configured to house the food product, is inserted in the closed internal housing but is not fixed to the upper or lower film. The food packaging described herein allows a substantial reduction of plastic compared to those currently on the market, while guaranteeing its mechanical rigidity, and the long-term quality of the product. A method for producing the packaging is also disclosed.

The present invention is directed to a monoaxially oriented, cross-linked multilayer film.

The invention is further directed to a method of producing and preserving a food product using such a film, bag or pouch and to a packaged food product obtained therefrom.

The present disclosure is directed to a flexible pouch. In an embodiment, a flexible pouch is provided and includes opposing flexible laminates sealed along a common peripheral edge to form a storage compartment. Each flexible laminate has at least three layers comprising (A) a seal layer, (B) an outermost layer, and (C) an adhesive layer between the seal layer and the outer layer. The adhesive layer comprises a solvent-free polyurethane adhesive composition. An alcoholic beverage is present in the storage compartment. The flexible pouch has a solvent residue less than 1.0 mg/m.sup.2, and a bond strength greater than 200 gm/15 mm after a 60-day liquor resistance test.
