Method of manufacturing an active moisture control material, wherein the material is formed from a base board comprising cellulose fibers and having a basis weight in the range of from 50 to 500 g/m2 and having a bulk of at least 1.2 cm3/g, wherein the method comprises a surface treatment of at least one side of said base board with a surface treatment composition comprising carboxymethyl cellulose (CMC) and a metal salt, wherein said surface treatment composition comprises carboxymethyl cellulose in a range of from 2 to 10 weight-% based on the total solid content of said surface treatment composition, and the metal salt in a range of from 10 to 30 weight-% based on the total solid content of said composition.

Moisture control material

The present invention relates to a material suitable for use in packages comprising nano-sized cellulose and an ethylene scavenging or ethylene absorbing agent. The invention also relates to methods for manufacturing such material, which may be paper, label, paperboard, plastic or film products.

Ethylene scavenging material suitable for use in packages

An active moisture control material comprising a fiber based material and at least one active additive, wherein said active additive is adapted to control moisture transfer in the active moisture control material, and wherein said moisture control material is produced in a paper or board making process, wherein the active additive is incorporated into said active moisture control material.

Active moisture control material for packaging

The present invention relates to a new process for creating foam in a process for manufacturing a paper or board product. According to the present invention, certain types of antimicrobial starch is used in the creation of the foam.

Process for creating a foam utilizing an antimicrobial starch within a process for manufacturing a paper or board product

The present invention relates to a method for applying a wallpaper material onto a surface comprising the steps of providing a liquid suspension comprising cellulosic fibers wherein at least part of said cellulosic fibers comprises microfibrillated cellulose and wherein said liquid suspension has a dry content of at least 10% by weight, applying at least one layer of said liquid suspension onto the surface, drying said liquid suspension layer after it has been applied onto the surface, and thereby forming a dry fiber web layer, wherein said fiber web layer forms said wallpaper material.
