Also disclosed is a sealed container comprising a lidding film according to the invention and a polymer tray wherein the lidding film is heat sealed to the top edge of the polymer tray via the non-oriented polyethylene, thereby enclosing a product within a recess defined by the polymer tray. Also disclosed is a method of producing a lidding film.

The present disclosure provides a flexible multilayer film. The flexible multilayer film includes at least three layers. One of the layers is a seal layer and one of the layers is a barrier layer. The seal layer is an ionomer. The backing layer is in direct contact with the seal layer. The backing layer is an ethylene/α-olefin multi-block copolymer.

The disclosed articles, apparatus, methods, and compositions provide for the integration of different and environmentally-friendly processes for extraction, stabilization, and formulation of active compounds with health and/or other benefits from lignocellulosic by-products of food processes. The active compounds can include one or more of polyphenols, flavonoids, o-diphenols, anthocyanins, and phenolic acids. A high-pressure, high-temperature extraction process provides a means to recover a substantial portion of the active compounds from a biomass feedstock. The corresponding extract can be encapsulated, which provides a convenient form for stabilization and delivery of the active compounds into a final product, for example an active packaging material or corresponding actively packaged food item.

The invention provides a polyolefin-based resin film including a polyolefin-based resin composition that comprises a propylene-α olefin random copolymer, an ethylene-butene copolymeric elastomer, and a propylene-butene copolymeric elastomer, wherein (1) the polyolefin-based resin composition contains 2 to 9 parts by weight of the ethylene-butene copolymeric elastomer and 2 to 9 parts by weight of the propylene-butene copolymeric elastomer based on 100 parts by weight of the propylene-α olefin random copolymer; (2) the polyolefin-based resin film exhibits a thermal shrinkage rate after heating at 120° C. for 30 minutes of 25% or less in a direction in which the thermal shrinkage rate after heating at 120° C. for 30 minutes is larger between a longitudinal direction and a lateral direction of the polyolefin-based resin film; and (3) a planar orientation coefficient ΔP calculated from a refractive index of the polyolefin-based resin film is 0.0100-0.0145.

The present invention relates generally to the field of multi-layer flexible packaging material. In particularly, the present invention relates to a multi-layer flexible packaging material comprising a paper layer, an aluminium layer, a nanoclay barrier coating layer, and a sealing layer applied to the surface of the nanoclay barrier coating layer representing the inner surface of the multi-layer flexible packaging material, said multilayer flexible barrier material being deprived of a polyolefin layer, such as a polyethylene (PE), polyethylene terepthalate (PET) or a polypropylene (PP) layer. The present invention further relates to the use of the multi- layer flexible packaging material in accordance with the present invention to package dry food.

Described herein is a sheet comprising: a multi-layer structure comprising: a plurality of layers including an uppermost layer and a lowermost layer, each of the plurality of layers having a molecular orientation that results in a stress value for each layer; wherein the stress value of at least two of the plurality of layers are non-zero and different from one another; and wherein the multi-layer structure has a net stress value that is less than the greater stress value of the plurality of layers.

The use of an aqueous polyurethane dispersion adhesive is described for producing composite foils which are biodisintegratable at home compost conditions where at least two substrates are adhesive-bonded to one another with use of the polyurethane dispersion adhesive, where at least one of the substrates is a polymer foil which is biodisintegratable at home compost conditions. At least 60% by weight of the polyurethane is composed of diisocyanates, polyesterdiols, and at least one bifunctional carboxylic acid selected from dihydroxy carboxylic acids and diamino carboxylic acids, wherein the polyurethane has no melting point above 20° C. or wherein the polyurethane has a melting point above 20° C. with an enthalpy of fusion lower than 10 J/g, and wherein a film of the polyurethane adhesive is biodegradable at home compost conditions.

A packaging body configured with a packaging film, in which the outermost layer is a polyethylene-based resin layer and the polyethylene-based resin layer is uniaxially or biaxially stretched.

An improved sheet for making a three-dimensional article for holding food, such as a food tray, and a method of making a three-dimensional article. The sheet comprises a substrate and a laminate film. The laminate film may comprise a ceramic film and a copolymer layer. The copolymer layer can repair any cracks that occur due in the ceramic film when the sheet is thermoformed. The food tray is considered a single material that is recyclable.

The present disclosure relates to a polymer film, a preparation method of the same, and a polymer film laminate. Specifically, it relates to a new type of polymer film, which is thin and exhibits excellent absorption performance while having excellent flexibility and mechanical properties. In addition, the polymer film is free from scattering or leaking, and does not require an auxiliary substance such as pulp, so that products can be made thinner and the manufacturing process and costs may be reduced. In addition, the present disclosure also relates to a preparation method of the above-described polymer film, and a polymer film laminate including the new type of polymer film.
