Food, consumer, and industrial product packaging materials are provided by embodiments of the present invention. Films and laminates based on a combination of negatively charged polysaccharides are provided as such packaging materials. The films can be prepared by mildly treating soft wood with steam followed by alkali extraction and enzymatic treatment. Negatively charged non-cellulosic polysaccharides are isolated with weight average molecular weight Mw higher than 10,000 g/mol and molecular structure comprising a xylan main chain substituted with more than 15 molar % of glucuronic acid and more than 5 molar % arabinose. The negatively charged non-cellulosic polysaccharides can be casted from water solution on a suitable carrier and surface acetylated or coated with acetylated polysaccharide to obtain oxygen and water barrier packaging laminate. Inventive packaging materials can have strength at break above 55 MPa, elongation to break above 2.5%, cohesive and adhesive properties and good oxygen and moisture barrier properties.

The present disclosure offers an improvement in papermaking methods and products, by providing a tissue sheet and a method to obtain a tissue sheet, with improved absorbency at a given basis weight. Thus, by way of example, the present disclosure provides a single ply tissue sheet having a basis weight greater than about 50 gsm and a specific vertical absorbent capacity greater than about 6.0 g/g.

There is described a label comprising a self supporting sheet of a biopolymer, preferably cellulose (e.g. regenerated cellulose, cellulose acetate and/or PLA) said sheet being substantially transparent to visible light when uncoated characterized in that the sheet comprises: (a) a first coating on at least one surface thereof to aid printability thereon; (b) a second coating comprising an adhesive dispersible in an aqueous medium; and (c) optionally a third coating to modify water permeability through the sheet. The labels are to be applied to articles such as glass containers. Preferred labels are wet glue cellulose labels for example where the first coating also comprises a copolymer of vinyl chloride and vinyl acetate to aid water permeability and hence rapid drying of the label on an article.
