A cover film (1) for sealing a base film (2) of a blister pack for drugs, comprising two outer layers, namely, a cover layer (3) and a sealing layer (4), and one or more intermediate layers (5) situated between the cover layer (3) and the sealing layer (4), characterized in that the cover layer (3) and the sealing layer (4) are polypropylene layers (6, 7, 10).

A fresh produce package includes a laminated polymer film having water transport windows that impart a limited, controlled water vapor transport rate (MVTR), thereby avoiding produce desiccation, while also avoiding excess moisture pooling. The film comprises a low MVTR layer, such as heat-sealable PET, laminated to a high MVTR layer, such as nylon, PLA, or cellulose. The film includes lamination gaps, for example created using an adhesive spray-blocking mask or an adhesive-applying roller with insets. A cutting device, such as a laser or die-cutter, forms moisture transport windows (MTWs) by cutting out panels of the low MVTR layer in the gaps while leaving the high MVTR layer in place. Container seams can be formed by heat sealing of the low MVTR layer to itself, or to an underlying tray. The film can be gas-impermeable, and can include microperforations to establish a modified gas atmosphere within the package.

An object to be achieved by the present invention is to provide a gas barrier film having excellent acid resistance, transparency, and gas barrier properties. The gas barrier laminated body of the present invention is a laminate, in which an inorganic thin-film layer is laminated onto at least one of surfaces of a polymer substrate, and the inorganic thin-film layer mainly contains Al and Si, and a ratio of an Al content amount between before and after treatment of immersing the laminate into aqueous solution of hydrochloric acid that has concentration of 1 mol/L for one hour satisfies a formula of (Al Content Amount After Treatment)/(Al Content Amount Before Treatment)?100?75.

The present disclosure generally relates to a method for providing a barrier coating on a hollow container (100) comprising molded pulp. The method comprises providing a polymeric powder coating onto the interior surface (105a) and at least a portion of the exterior surface of the container (100) prior to curing and/or melting the powder coatings. The present disclosure also relates to a hollow container (100) formed by the method.

Disclosed is a biodegradable container comprising a biodegradable material and a reinforced barrier film coated onto the biodegradable material, wherein the reinforced barrier film comprises graphene nanoplatelets dispersed in a biodegradable polymeric substrate.

A packaging structure and methods of manufacture are provided herein. The packaging structure comprises a first film layer comprising an outer surface and an inner surface. An in layer comprising titanium dioxide is disposed on the inner surface of the first film layer. An oxygen barrier coating is disposed adjacent the ink layer. A second film layer adhesively joined to the oxygen barrier coating wherein the second film layer metalized polyethylene. A cold seal adhesive is applied to the second film layer opposite the oxygen barrier coating.

A sealed package includes first and second opposed plies, each with first and second edges, wherein the first edges of the first and second plies have overlying sections that form a first seal, and wherein the second edges of the first and second plies have overlying sections that form a second seal; the first and second plies include polymeric film. A score line is present adjacent the second seal, the score line only partially penetrating the first ply and extending less than a full width of the first ply.

This product based on leaven comprises a package containing living leaven closed with a gas tight seal. The leaven is in a nitrogen atmosphere.

The present invention provides a stabilized hypohalous acid solution (or formulation thereof), which may be conveniently packaged for sale, or stored for later use on demand. The invention further provides methods of making the stabilized hypohalous acid solutions, as well as methods of use for disinfecting mammalian tissue, including wounds and burns, and treating skin irritations, among other uses.

A liquid-containing combination container includes a first container that contains a liquid and that has oxygen permeability, a second container that contains the first container and that has an oxygen barrier property, and an oxygen absorber that absorbs oxygen in the second container. Pressure in the first container is 1 atm or less.
