摘要:
A paperboard substrate that can be used to provide a food packaging particle is provided having a water vapor barrier layer comprising HDPE in combination with a nucleating agent which is extruded on to a paperboard substrate. The resulting substrate has sufficiently good water vapor barrier when properties that dry foods such as cereals do not require a bag or inner liner as a separate moisture barrier.

Two-component adhesion composition suitable for extrusion coating paper substrates which comprises: a) from 70 to 98 wt % of high melt strength polypropylene (A) with a branching index g′ of 0.9 or less; and b) from 2 to 30 wt % of a component (B) selected from the group consisting of: (i) maleic anhydride-modified polypropylene (MAPP); (ii) maleic anhydride-modified polypropylene wax; (iii) polypropylene homopolymer with high melt flow rate; or (iv) ethylene-vinyl acetate-based hot melt adhesive, and its use.
摘要:
Composite boards are disclosed herein. An example of the composite board includes a first outer layer, a second outer layer, and a middle layer positioned between the first and second outer layers. The first and second outer layers each include chemical pulped cellulose fibers and low moisture absorbing fibers. The middle layer includes the cellulose fibers and a moisture repelling agent. Also disclosed herein are art frames that include the composite boards.

Waterproof engineered floor and wall planks have a veneer layer, an extruded plastic composite core, a click-lock edge fastening system, and, alternatively, an underlayer.
摘要:
The method for manufacturing film-coated paper includes steps including heating and melting an original raw material composed of PP and PE and re-granulating into a second raw material, mixing a first raw material and the second raw material followed by heating, melting, and mixing again wherein the first material is PP, re-granulating the mixed material, heating and melting the re-granulated material, extruding to form a coating film, and coating the coating film on a paper surface. Thereby, a film-coated paper which can resist higher temperature and has better yield rate is provided.

摘要:
A non-transparent paper is described for non-transparent art or graphic design sketches, which prevents seepage of the inks, it accepts any type of gel, water-based, solvent-based, oil-based or mixed inks and solid materials for sketching and drawing, as well as fixatives for the solid materials. This paper consists of a lamination of at least two sheets of uncoated bond paper, inserting at least one intermediate layer of pigmented opacifying emulsion between both sheets, applied between the layers of paper to prevent transparency and the seepage of inks from one face of the lamination to the other. This layer of emulsion contains at least one opacifying pigment, at least one adhesive, agents to control viscosity and surface tension and other components. The outside layers of paper have a drying capacity which fixes the materials used for the sketching and prevent outlines made on one face passing to the adjacent sheets of paper, and also has a texture suitable for receiving any dry material for drawing or sketching.
摘要:
A thermo-insulating packaging material including a paper-based substrate layer, a paper-based top layer and a thermal-insulating composition positioned between the paper-based substrate layer and the paper-based top layer, the thermal-insulating composition including a filler, an organic binder and a plasticizer.
摘要:
Thermoplastic polyolefin polymer composition, polymer chip, fiber, woven or nonwoven fabric, film, closures, laminates can comprise a polymer, a polymer and a nonvolatile polymer-compatible carboxylic acid. Thermoplastic polyolefin polymer composition can also comprise a polymer, a cyclodextrin-modified polymer and a nonvolatile polymer-compatible carboxylic acid. The carboxylic acid moiety of the polymer composition can react with basic materials in the polymer environment and reduce release of the basic material. The cyclodextrin can act to absorb or trap other contaminants or odors in the environment.
