The invention relates to a wrapping material (1) for wrapping an article (10), which is based on glassine paper with a grammage in the range of 25 to 50 g/m.sup.2, wherein the wrapping material (1) is present in the form of a web. The web has i. a first side face (S1), ii. a second side face (S2) situated opposite the first side face (S1), iii. at least one web portion (B) having a first and a second outer region portion (2, 3) and inner region portions (4, 5, 6, 7, 8), wherein the inner region portions are arranged between the outer region portions (2, 3). A heat-sealable coating is applied to the glassine paper on at least one of the two side faces (S1, S2) in at least one first outer coating region (2a-2g) in the first outer region portion (2) of the web portion (B). A heat-sealable coating is applied to the glassine paper on at least one of the two side faces (S1, S2) in at least one second outer coating region (3a-3g) in the second outer region portion (3) of the web portion (B).

Provided is an adhesive containing a polyurethane resin (A), an epoxy resin (B), and an isocyanate crosslinking agent (C). The epoxy resin (B) contains a hydroxyl group-containing epoxy resin that has an epoxy equivalent of 450 g/eq or more and 3000 g/eq or less and that has a hydroxy group.

The powder adhesive comprises a thermoplastic resin and particles of an aromatic compound, wherein the particles of an aromatic compound are particles of a compound that has an aromatic ring and an azo bond bonded to the aromatic ring, or are particles of a compound comprising a heteroaromatic ring comprising nitrogen atom; the thermoplastic resin comprises an ester group; and, designating Es (mmol/g) as an ester group concentration in the thermoplastic resin, M (mass %) as a content of the aromatic compound particles in the powder adhesive, and N (mmol/g) as a nitrogen atom concentration in the aromatic compound particles, Es is from 1.0 mmol/g to 4.5 mmol/g, M is from 1.010.sup.4 mass % to 1.010.sup.0 mass %, and N is from 5.0 mmol/g to 15.0 mmol/g.

An adhesive composition that enables adhesion between metals, between a metal and an organic material, and between an organic material and an organic material, have at the same time an excellent storage stability, and are capable of maintaining an excellent adhesive strength even in a high temperature hydrothermal environment, is provided. The adhesive composition according to the present invention comprises an epoxy resin, an epoxy modified silicone resin, an acrylic resin, and a curing agent, the above-mentioned epoxy resin comprising a bisphenol bifunctional epoxy resin and an epoxy resin with trifunctionality or higher functionality, and the above acrylic resin comprising a binary copolymer of methyl methacrylate-butyl acrylate-methyl methacrylate or a modified product thereof.

An article suitable for food contact includes a first substrate and a second substrate which are joined by an adhesive, said first substrate including a support coated with a silicone coating suitable for food contact, said adhesive being inserted between the two substrates and being in contact with the silicone coating of said first substrate. Said adhesive is a structural silicone adhesive suitable for food contact and obtained by crosslinking a silicone composition which is crosslinkable by a polyaddition reaction.

The present invention discloses a composite film with clear texture and high quality and a preparation process thereof, relating to the technical field of composite films. The composite film with clear texture and high quality comprising a texture layer, a protective coating layer, a printed coating layer, an adhesive layer and a first substrate layer sequentially laminated from a top layer to a bottom layer, wherein the protective coating layer is provided on a surface of the texture layer facing the first substrate layer, the printed coating layer is provided on a surface of the protective coating layer facing the first substrate layer, and the texture layer is connected to the first substrate layer. The composite film with clear texture and high quality can realize multi-texture alignment printing by combining texture layers with printing, allowing one upper to have a variety of different textures and a variety of different colors.

The invention relates to a wrapping material (1) for wrapping an article (10), which is based on glassine paper with a grammage in the range of 25 to 50 g/m.sup.2, wherein the wrapping material (1) is present in the form of a web. The web has i. a first side face (S1), ii. a second side face (S2) situated opposite the first side face (S1), iii. at least one web portion (B) having a first and a second outer region portion (2, 3) and inner region portions (4, 5, 6, 7, 8), wherein the inner region portions are arranged between the outer region portions (2, 3). A heat-sealable coating is applied to the glassine paper on at least one of the two side faces (S1, S2) in at least one first outer coating region (2a-2g) in the first outer region portion (2) of the web portion (B). A heat-sealable coating is applied to the glassine paper on at least one of the two side faces (S1, S2) in at least one second outer coating region (3a-3g) in the second outer region portion (3) of the web portion (B).
