A computer server includes processor and memory hardware. The processor hardware executes instructions including parsing a hypertext transfer protocol (HTTP) request from a first user agent to identify a first data object matching a set of characteristics and generating a new data element based on the HTTP request. The instructions include, in response to the first data object being present: extracting a first set of serialized data elements and serializing them with the new data element to generate a second data object. The instructions include, in response to the first data object being absent and a user associated with the first user agent being identifiable: determining a second set of serialized data elements based on an identity of the user, and serializing them with the new data element to generate the second data object. The instructions include transmitting an HTTP response including the second data object.

[Problem to be Solved] To prevent delamination of a film layer in a sheet material container in which an enclosing portion is formed in an interlayer between a first film layer and a second film layer.

[Solution] A sheet material container includes a container body 6, and an inner container 7 that is covered by the container body 6 and defines an accommodation space, wherein the container body 6 is formed of a sheet material 3 including a first film layer 1 and a second film layer 2 disposed inside the first film layer 1, the sheet material 3 has a joint portion 32 at which an interlayer between the first film layer 1 and the second film layer 2 is joined and an enclosing portion 51 in which a filler can be enclosed in the interlayer between the first film layer 1 and the second film layer 2, and the first film layer 1 has an extruded multilayer structural part having a polyolefin resin layer 11/an ethylene-vinyl alcohol copolymer resin layer 12 on a side facing the enclosing portion 51.

A packaging material for a power storage device and a power storage device using the same, a method of producing a packaging material for a power storage device, and a method of selecting a sealant film used as a sealant layer in the packaging material for a power storage device are provided.

A film is described comprising a (meth)acrylic polymer and a polyvinyl acetal (e.g. butyral) resin. In some embodiments, the film has a glass transition temperature (i.e. Tg) ranging from 30° C. to 60° C. In some embodiments, the film has a gel content of at least 20% or greater. In some embodiments, the film has an elongation at break of at least 175%. The film typically comprises photoinitiator as a result of the method by which the film was made. The film may be a monolithic film or a layer of a multilayer film.

Described herein are recyclable films with an outer surface comprising a polar polymer, such as polyamide, an inner surface comprising a sealant, and a polar polymer compatibilizer located between the polar polymer and the sealant. Preferably the outer surface is an outer layer of biaxially oriented polyamide and the inner surface is a multilayer inner film comprising the sealant and the compatibilizer.

A composite film includes a) a self-supporting layer of a polymer film (such as a polyester), b) an optional primer layer on the polymer film layer, wherein the primer layer includes a PVdX (X being halo), acrylic or vinyl resin; and c) a layer of heat seal composition on the primer layer, wherein the heat seal composition includes a polyolefin plastomer (POP) resin and a tackifier that constitutes at least 20 wt % of the heat seal composition. The composite film may be formed by applying a coating composition including the heat seal composition in a solvent to a primer layer on the polymer film or directly on the polymer film in absence of the optional primer layer, and then evaporating the solvent. The composite film may be heat-sealed to a surface of a container or a self-supporting film.

A resin composition contains: (A) an ethylene-vinyl alcohol copolymer; (B) an olefin polymer; and (C) a sorbic acid ester; wherein the sorbic acid ester (C) is present in an amount of 0.00001 to 10 ppm based on the weight of the resin composition. The resin composition exhibits reduced susceptibility to coloration.

A decorative sheet comprises a substrate layer; a pattern layer provided on the first front surface of the substrate layer; and a thermoplastic resin layer provided on the second front surface of the pattern layer. A test piece of 8 mm width from the decorative sheet is taken; the storage modulus is measured with an initial chuck distance of 10.77 mm, a start temperature of 30° C., an end temperature of 150° C., a temperature increase rate of 5° C./min, and a measurement frequency of 1.0 Hz. The ratio of the difference between the second storage modulus and a third storage modulus when the decorative sheet changes from the transition region to a rubbery flat region to the difference between a first storage modulus when the environmental temperature is 30° C. and a second storage modulus when the decorative sheet changes from a glassy region to a transition region is 3.5 or less.

A laminated sheet includes a substrate having sheet shape and a sealant layer provided on the substrate. The sealant layer includes a first resin layer containing a crystalline polyester, and a second resin layer located between the first resin layer and the substrate and containing no polyester, the second resin layer is joined to the substrate and the first resin layer, and a crystallization temperature of the crystalline polyester is 120° C. or higher and 150° C. or lower.

An oxygen-absorbing film including at least, from an outer layer side, a surface substrate layer having an oxygen barrier property, an oxygen-absorbing resin layer, and an inner surface substrate layer that contains a stretched PET substrate and is heat-sealable. The surface substrate layer, the oxygen-absorbing resin layer, and the inner surface substrate layer are laminated in this order. The oxygen-absorbing film provides an oxygen-absorbing film suitable as a packaging material that excels in oxidation suppression of packaging contents and in non-sorption of aroma components and also exhibits excellent tearability.
