The technology disclosed herein concerns films and products providing superior OTR and WVTR properties.

The present invention provides a double container capable of suppressing the deterioration of the gas barrier property under high humidity environment. According to the present invention, provided is a double container comprising a container body, wherein the container body has an outer shell and the inner bag, the container body is configured such that the inner bag contracts as content is reduced, and the inner bag comprises an inner layer, a gas barrier layer, and an outer layer, in order from an inside of the container body.

Products, containers and methods for storing food that is sensitive to low temperatures in freezers are provided. The products comprise a food and a storage unit, and the storage unit comprises a first container that contains the food and a second container that holds the first container and the food and which provides a space between the first container and the second container. The storage unit is used in methods to freeze and thaw the food that result in the food having its desired or original consistency after the food is thawed.

A gas barrier laminate includes a gas barrier film having a gas barrier layer on at least one side of a substrate including a first polypropylene film, and at least one second polypropylene film laminated on the gas barrier film. The gas barrier layer is obtained using a composition for forming the gas barrier layer that contains a resin and a first silicon compound. The first silicon compound is at least one of a silicon alkoxide represented by a following general formula (1) and a hydrolysate thereof, and a chlorine content as measured by combustion ion chromatography is more than 0.0008% by mass and 0.0080% by mass or less relative to a total mass of the gas barrier laminate. Si(OR.sup.1).sub.4 . . . (1) (In the above general formula (1), OR.sup.1 represents a hydrolyzable group.)

A barrier coating comprising a polyvinyl alcohol, a polyacrylic acid, and a carbodiimide wherein the barrier film is formed at less than 120 C. is disclosed. A laminate comprising the barrier coating comprising a polyvinyl alcohol, a polyacrylic acid, and a carbodiimide is also disclosed. The polyacrylic acid can comprise a poly (meth) acrylic acid with a molecular weight from 2000 to 400,000 g/mol, and a degree of neutralization of from 2 to 50%. The polyvinyl alcohol can have a saponification degree of at least 80% and a molecular weight of from 10,000 to 300,000 g/mol. The disclosed barrier coating provides good OTR at high humidity without the need for high curing temperatures or non-commercially viable cure times.

A container including a tray and a lidding film is provided. The lidding film is removably coupled to the tray and includes a breakable layer, a lidding layer coupled to the breakable layer, and a PSA layer. A reseal portion of the breakable layer is sealed to a flange of the tray. The PSA layer is arranged between the lidding layer and the breakable layer. The PSA layer includes a reseal portion to adhere to the reseal portion of the breakable layer. The reseal portion of the breakable layer separates from an inner portion when the container is initially opened such that the reseal portion of the breakable layer remains sealed to the flange and the inner portion of the breakable layer remains coupled to the lidding layer. The container is resealed by adhering the reseal portion of the PSA layer to the reseal portion of the breakable layer.

A base paper for vapor deposition paper, the base paper including, on at least one surface of a paper substrate, a clay coat layer and a resin layer in this order on the paper substrate, in which the clay coat layer includes an inorganic pigment and a binder, the mass ratio (inorganic pigment/binder) of the inorganic pigment to the binder in the clay coat layer is from 25/75 to 75/25, and the coating amount in terms of solid content of the clay coat layer is 8 g/m.sup.2 or more and 20 g/m.sup.2 or less.

A gas barrier substrate comprising a biodegradable composite, the biodegradable composite comprising a polymeric matrix and a sustainable filler comprising protein. Also articles of manufacture comprising the gas barrier substrate and methods of limiting gas permeation using the gas barrier substrate.

A barrier-type paper (18) with a non-barrier paper (16) uses suitable laminating adhesives to form a food packaging material. More specifically, a preferred embodiment of the invention is directed to a metallized or aluminum oxide coated paper sheet (20, 21) laminated to a bleached paper sheet (16) using suitable laminating adhesive (26). The following additional layers may be added: a cold seal adhesive layer (33), an ink layer (34), and/or a cold seal release over lacquer layer (32).
