摘要:
A barrier paper includes a paper base material and a barrier layer containing cellulose fibers formed on the paper base material, in which an integrated value from 10.0 μm to 500.0 μm, obtained from a volume-based particle size distribution diagram when a dispersion containing the cellulose fibers is measured by laser diffraction, is 30% or more.
摘要:
A system and method for producing a board product made from paper products that have a pre-scored facing in addition to a medium (sometimes called fluting). Conventional corrugated board may feature a cross-corrugated medium and one or more facing that have no score lines that are imprinted (at least prior to assembly with the corrugated medium). Such a conventional board product may be inferior because any score lines that are imprinted will damage the underlying corrugated medium in some manner. A breakdown in the strength of the underlying medium leads to poor precision when the eventual board product is scored, cut, and bent. A lack of precision in folding a board product is known as fishtailing as any articulated portion of the board product may not maintain a precise plane of articulation when bent. Hence, the articulated portion “fishtails” out of alignment. Having precisely located impression lines in register to underlying flutes of a medium ensures correct and precise articulation.
摘要:
The present invention relates to a method for manufacturing of a laminated cellulose-based liquid or semi-liquid food packaging material, wherein the laminated packaging material has a bulk material layer comprising a low-density cellulose spacer layer, an outside module comprising a substrate layer having a print surface and an inside material module comprising a barrier layer or barrier coating. The invention further relates the laminated packaging materials obtained by the method and to a packaging container for liquid food packaging, comprising the laminated packaging material or being made from the laminated packaging material obtained by the method.
摘要:
A laminated packaging material for food packaging, comprises a core layer of paper or paperboard, which on a first side intended to be directed towards the outside of a packaging container, has, in the following order, a dry pre-coating for receiving a printed décor of an aqueous, pigment-based, ink-jet printing ink, a pigment-based ink-jet printed ink décor layer and further laminated onto the printed décor layer, a protective outermost layer of a thermoplastic polymer. Also disclosed is a method for manufacturing of the packaging laminate and to a packaging container that is made from the laminated packaging material as well as to a pre-coating composition for use in the laminated packaging material and in the manufacturing thereof.
摘要:
This invention relates to the composition of a chitosan coated paper wherein the chitosan may be derived from a variety of sources. Methods of using chitosan as a surface coating or pulp additive to tune the properties of paper and paperboard products are also described. The chitosan applied is a bio-based and environmentally friendly barrier coating and/or additive material for the manufacture of functional paper and paperboard products, specifically as evaporative cooling media requiring wet strength and structural integrity, wicking, and moisture resistance as an alternative to conventional phenolic-based resins. The solid-state fermentation method to produce chitosan and its derivatives offer renewable bio-based materials towards the manufacture of functional paper products that are eco-friendly but also offer uncompromized performance levels.
摘要:
A method in which an interior trim part for a vehicle is produced. The method includes the steps of providing a block of material comprising a plurality of paper layers connected to each other by at least one resin, cutting the block into slices, wherein a cutting plane has an angle between 5° and 85° in relation to layer planes of the paper layers, providing a flexible support layer and applying at least one of the slices to the flexible support layer to obtain a flexible composite layer, and providing a rigid carrier and applying the flexible composite layer directly or indirectly to the carrier.

In some instances, an adhesive may include a plasticizer in an amount of about 15% or greater by weight of the adhesive; and a cellulose acetate having a relationship between an acetyl value and an intrinsic viscosity according to Equation 1 of about 2.80 to about 3.85 (or about 2.80 to about 3.20): AV 2 + IV 2 1000 . Equation 1
摘要:
A composite construct comprising a side wall extending at least partially around an interior of the composite construct. At least a portion of the side wall comprises at least one laminate, and the at least one laminate comprises at least one layer of material that comprises a first renewable polymer. The composite construct can also comprise at least one injection-molded element comprising at least a second renewable polymer.
