The present invention relates to anti-odour packaging films and to packages made therefrom. In particular, the present invention relates to anti-odour multilayer gas barrier films including specific anti-odour compounds in at least in one inner layer. These anti-odour films are particularly suitable for food packaging, especially poultry packaging.

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.

The present disclosure relates to a gas barrier layered body including: a substrate layer containing a polyolefin-based resin; a first polyvinyl alcohol-based resin layer; a Si or Al-containing thin film layer; and a second polyvinyl alcohol-based resin layer, in the stated order, in which a logarithmic decrement at 100? C. of the first polyvinyl alcohol-based resin layer as measured by a rigid-body pendulum type physical property testing instrument is 0.20 or less and a logarithmic decrement at 125? C. is 0.30 or less, and an indentation hardness of the second polyvinyl alcohol-based resin layer as determined by a nanoindenter is 0.5 to 1.0 GPa.

Provided is a method for producing a gas barrier paper packaging material which can impart sufficient gas barrier properties even when a barrier coating agent for forming a barrier layer is applied in a dry amount of 2 g/m.sup.2 or less. The method for producing a gas barrier paper packaging material at least includes: a barrier layer forming step of applying a barrier coating agent to one side of a sealant film to form a barrier layer; and a lamination step of laminating the barrier layer and a paper substrate layer via an adhesive layer.

A gas barrier laminate includes a substrate, an inorganic vapor deposition layer containing an inorganic oxide, and a coating layer, which are laminated in this order, the coating layer being composed of a single layer or a plurality of layers. The coating layer contains a carboxy group-containing polymer, and at least one type of polyvalent metal-containing particles, a total X-ray fluorescence intensity of metal elements contained in the polyvalent metal-containing particles is 3.0 kcps or greater and 8.0 kcps or less, and an absorbance X of the gas barrier laminate 10 obtained by subtracting an absorbance X.sub.2 at a wavelength of 500 nm from an absorbance X.sub.1 at a wavelength of 350 nm measured with an ultraviolet-visible spectrophotometer after hot water treatment at 130? C. for 30 minutes using a 0.3 mass % L-cysteine aqueous solution satisfies the following formula: X=X.sub.1?X.sub.2?0.02 (abs).

A modified ethylene-vinyl alcohol resin composition including: a modified ethylene-vinyl alcohol resin having 1 to 16.5 mol % of a primary hydroxy group structural unit at a side chain; and a conjugated polyene, wherein the resin composition exhibits not less than five melting peaks when subjected to differential scanning calorimetry (DSC) according to specific analysis conditions.

Provided is a biodegradable film for cigarette packaging, the film including a first film layer applied such that one surface thereof faces a cigarette product, a third film layer applied such that one surface thereof is exposed to the outside, and a second film layer positioned between the first film layer and the third film layer. In the biodegradable film, the first film layer, the second film layer and the third film layer are each formed with different compositions, and at least one of the first film layer, the second film layer and the third film layer includes a biodegradable material. The biodegradable film has a biodegradation rate of 90% or more after 60 days, and has a heat shrink ratio of 4.0% or more.

A multilayer tube laminate for producing a tube container, having: at least one paper layer, a polymer layer with a sealable exposed polymer surface on one side of the at least one paper layer, and a polymer coating from an olefin-based material applied directly on the at least one paper layer on another side of the at least one paper layer facing away from the sealable polymer layer;
the polymer layer being formed to more than 90% by weight from a biodegradable polymer.

The disclosure relates to a liner for containers or packages. The liner includes several polymer layers, exhibits a barrier function (e.g., gas or moisture barrier function), and is peelably attachable to one or more container/package surfaces. When the liner lines a package or container the package or container exhibits the liner's barrier function, and the liner can be peeled from the package or container to facilitate recycling or disposal. The liner is thermoformable, and can thus be either shaped to conform to the shape of a pre-formed container or shaped simultaneously with formation of the container from a precursor material to which the liner is peelably bound, either prior to or during container formation.
