摘要： A method is provided for coating a fibrous web, in particular a fibrous web comprising nanocellulose fibres. The method includes steps of applying a coating agent to a textured surface region of a textured substrate, applying a fibre furnish or a wet fibrous web onto the coated textured surface region of the textured substrate, optionally dewatering to provide a wet fibrous web, and drying said wet fibrous web such that at least a portion of said coating agent is transferred to said fibrous web. The method provides a coated fibrous web with improved barrier properties.

摘要： A biodegradable packaging material, a method of manufacturing the same, as well as products made of the material wherein the manufacture comprises extrusion onto a fibrous substrate one or mote polymer coating layers including at least one layer of a polymer blend consisting of (i) 20-95 wt-% of polylactide having a high melt index of more than 35 g/10 min (210° C.; 2.16 kg), (ii) 5-80 wt-% of polybutylene succinate (PBS) or a biodegradable derivate thereof, and (iii) 0-5 wt-% of one or more polymeric additives. The components of the blend are melted and blended in connection with the extrusion step. The goal is to improve extrudability, increase machine speed in extrusion and maintaining good adhesiveness to the substrate and wood heat-sealability of the coating. The products include disposable drinking cups and board trays, as well as sealed carton packages for solids and liquids.

摘要： The invention concerns a heat-sealable biodegradable packaging material, which comprises a fibrous substrate (1) and one or more polymer coating layers (2) extruded onto said substrate. According to the invention the packaging material includes at least one polymer coating layer (2) containing at least 70 weight-% of polylactide (PLA) and at least 5 weight-% of polybutylene succinate (PBS) or its derivate blended therewith. Optionally an acryl copolymer such as ethylene butyl acrylate glycidyl methacrylate terpolymer (EBAGMA) may be included in the polymer blend. The invention further concerns a heat-sealed container, such as a disposable drinking cup, and a heat-sealed product package made from the packaging material, as well as uses of PBS or its derivates as blends with PLA in extrusion coating, for improving adhesivity of the coating to the fibrous substrate and reduced raw edge penetration to the packaging material, especially penetration of hot coffee held in the drinking cup.
