Abstract:
A method for the production of a composite material comprising nanofibrillated polysaccharide, the method comprising the following steps: (i) providing a liquid suspension of the nanofibrillated polysaccharide; (ii) bringing said liquid suspension in contact with at least one additive, thereby forming a composite material suspension, wherein the composite comprises the nanofibrillated polysaccharide and the at least one additive, (iii) increasing the solid contents of said composite material suspension, thereby forming a high solid contents composite material suspension.
Abstract:
The present invention relates to a method for manufacturing a film having an oxygen transmission rate in the range of from 1 cc/m2/24 h to 500 cc/m2/24 h according to ASTM D-3985, at a relative humidity of more than 50% at 25° C., or higher than 75% at 25° C., or higher than 85% at 25° C., wherein the method comprises the steps of: providing a first suspension comprising a microfibrillated cellulose, wherein the dry content of the suspension is in the range of from 0.1 to 10% by weight, adding a wet strength additive to said first suspension, at an amount of from 0.1 to 10 weight-% based on the amount of microfibrillated cellulose (dry/dry), thereby forming a mixture of the microfibrillated cellulose and the wet strength additive, applying said mixture to a substrate to form a fibrous web and drying said web to form said film. The present invention also relates to a film produced according to the method.
Abstract:
A substantially dry composite material comprising a nanofibrillated polysaccharide and two or more additives, wherein the composite nanofibrillated polysaccharide is a microfibrillated cellulose and wherein the additives are lime milk and carbon dioxide, wherein the additives are allowed to react with each other and forming a precipitated calcium carbonate on the nanofibrillated polysaccharide, thereby forming a composite product comprising precipitated calcium carbonate and nanofibrillated polysaccharide.
Abstract:
The present invention relates to a web of fibrous cellulosic material derived from wood pulp, said web being suitable for three-dimensional moulding to form a packaging product, wherein the web comprises >40 wt % of soft wood chemical pulp and at least one strength enhancement agent, wherein the web has a grammage less than 400 g/m2, and wherein the cellulose fibers of said soft wood chemical pulp comprise a fiber curl of >9%.
