Boards have a mineral content, including magnesiumoxychloride and/or magnesiumoxysulphate, and may be finished with a DPL laminate decorative layer.

An adhesive composition contains an acid anhydride group-containing oil or fat (A) and a curing agent (B) having a reactive group reactive with an acid anhydride group. A laminate is obtained by placing an adhesive layer between a first substrate and a second substrate, and the adhesive layer includes the aforementioned adhesive composition. A package is obtained by forming a bag from a laminate obtained by placing an adhesive layer between a first substrate and a second substrate, and the adhesive layer includes the aforementioned adhesive composition.

There are provided a decorative sheet having excellent contamination resistance/tape resistance while maintaining high flaw resistance and a decorative plate. The decorative sheet includes: a base material; a matte layer formed on one surface of the base material; and a surface protective layer formed on the surface on the side of the matte layer of the base material, in which the matte layer and the surface protective layer are formed of an ultraviolet curable resin and the matte layer contains a spherical filler.

A packaging material comprising a graphene-reinforced polymer matrix composite (G-PMC) is disclosed. The packaging material has improved barrier resistance to gas and liquid permeants. Also disclosed is a method of improving barrier resistance of a polymer to a permeant, the method comprising forming a graphene-reinforced polymer matrix composite within the polymer. The packaging material may be used for packaging food, drug, perfume, etc. and to make various containers.

A method for creating a honeycomb core having venting pathways includes controlling where a resin is applied to sheets to form the venting pathways. A honeycomb substrate is then formed from the sheets.

A waterproof corrugated paper includes at least one stone paper medium and at least one stone liner paper, wherein the at least one stone paper medium includes a first fluting surface. A stone glue is utilized to adhere the at least one stone liner paper and several wave crests of the first fluting surface. The stone glue includes a linear polyolefin plastic material and an inorganic material. The linear polyolefin plastic material is 30 wt %-70 wt % based on the stone glue, and the inorganic material is 30 wt %-70 wt % based on the stone glue. The waterproof corrugated paper provided by the present invention is waterproof and frost-resistant, which is adapted to package cooled or frozen food. A manufacturing method, a manufacturing apparatus, and a usage of the waterproof corrugated paper are also provided in the present invention.

The invention relates to a can containing a liquid and/or a gaseous medium which has positive pressure or develops such during transport or storage, wherein the cylindrical can shell of the can consists mainly of paper or cardboard material and is closed at the bottom with a bottom element and at the top with a cover element, wherein the can withstands an internal pressure of at least 5 bar, wherein the innermost layer of the can shell consists of a straight-wound barrier layer having a longitudinally extending folded seam, wherein the barrier layer is a prefabricated laminate made of an inner diffusion-tight barrier film or an inner diffusion-tight barrier laminate and an outer kraft paper layer.

A method of forming a cushioning sheet includes forming a plurality of first sockets in a first layer; forming a plurality of second sockets in a second layer, each of the second sockets aligned with a corresponding one of the first sockets; positioning a cushioning insert within a void defined between each corresponding pair of the first and second sockets; and coupling the first layer to the second layer to retain the plurality of cushioning inserts within the voids.

Articles and methods for archival raised image printing is disclosed. The process includes modifying an electronic image, printing the image on a paper substrate to form a printed substrate, applying the printed substrate onto a barrier substrate via an applicator such that the applicator creates a wall around the outer edge of the image, coating the printed substrate with a varnish composition, and drying the printed substrate in a humidity controlled environment. This configuration provides an efficient system of archival printing to print raised images on an article.

A metal-clad laminate includes: an insulating layer; and a metal foil being in contact with at least one surface of the insulating layer. The insulating layer contains a cured product of a resin composition containing a polyphenylene ether copolymer having an intrinsic viscosity of 0.03 to 0.12 dl/g measured in methylene chloride at 25° C. and having an average of 1.5 to 3 specific groups per molecule at its molecular terminal, a thermosetting curing agent having two or more carbon-carbon unsaturated double bonds at its molecular terminal, and a thermoplastic elastomer. The metal foil includes a metal substrate, and a cobalt-containing barrier layer provided on at least a contact surface of the metal substrate, the contact surface being in contact with the insulating layer. The contact surface has a ten-point average roughness Rz of 2 μm or less as a surface roughness.
