The composite structure includes a fiber-containing layer, such as a fiberboard layer or other layer having fibers from natural and/or synthetic sources, and a mineral-containing layer covering the fiber-containing layer. The fiber-containing layer and mineral-containing layer can be shaped, sized and manufactured such that the composite structure formed therefrom is capable of being machined to form a storage article. The composite structure has advantages in that it can improve whiteness, opacity, ink adhesion, materials reduction, barrier properties, recyclability, and printability. The composite can reduce polymer mass requirements for heat seal, barrier, and fiber adhesion. Further improvements include economics, pliability, and flexibility that is increased over the pliability of the fiber-containing layer alone.

A foam flooring includes a stone-plastic base material structure, which sequentially comprises, from top to bottom, a first stable layer, a foaming layer and a second stable layer. The first stable layer and the second stable layer are both sheets with a PVC resin and filler powder as main components, with 25-40 parts by mass of the PVC resin and 55-75 parts by mass of the filler powder; and the density of the SPC foam flooring is 1.4-1.6 g/cm3. The foaming layer is arranged between the two stable layers, such that the overall density of the flooring is significantly reduced and reaches 1.4-1.6 g/m3; since the foaming layer is arranged inside, the surface strength of the overall flooring is not influenced.

The present disclosure provides a rigid high-gloss wear-resistant and scratch-resistant flooring. The flooring includes a surface layer, an intermediate Spc layer, and a decorative layer that are laminated; where the surface layer is prepared by combining a melamine glue and a color film; the intermediate Spc layer is prepared by mixing polyvinyl chloride resin, calcium carbonate, a plasticizer, and a stabilizer; and the decorative layer is prepared by a high-temperature material. The rigid high-gloss wear-resistant and scratch-resistant flooring is prepared by the melamine glue and the special color film, has an intermediate Spc layer, and has the decorative layer on a back side. The flooring is prepared by three different layers through a high temperature and a high pressure. The flooring has a surface that is highly wear-resistant, extremely scratch-resistant, cigarette burning-resistant, and non-deformable, and is suitable for use in various public places, with various styles, diverse specifications, and stability.

The invention relates to a sound protection panel for cladding a wall of an automotive vehicle, the panel includes a mass-spring system. The panel has a lower spring layer based on a resiliently compressible material, an upper mass layer based on resiliently compressible foam flakes, the flakes being bound together by a two-component fibre-based bonding agent comprising a core. The core is fusible at a high temperature or infusible, and a sheath fusible at a lower temperature, the flakes being fused with the sheath to form an upper agglomerated layer.

A self-adherent wall decoration has a body and two adhesive strips. The body is flexible and has a wear layer, a vinyl print layer, a waterproof core layer, and an underlayment layer. The wear layer is composed of poly(vinyl chloride), acrylate copolymer, dioctyl terephthalate, organotin thermal stabilizers, etc. The vinyl print layer is formed on the wear layer, and is composed of poly(vinyl chloride), acrylate copolymer, etc. The waterproof core layer is formed on the vinyl print layer, and is composed of poly(vinyl chloride), acrylonitrile-butadiene-styrene copolymer, etc. The underlayment layer is a poly(vinyl chloride) film, and is formed on the waterproof core layer.
