    Abstract: The present invention relates to a container for liquid containing food products, manufactured by press forming of a polymer coated fiber based substrate, said container comprising a bottom portion, a sidewall portion and a top flange portion,wherein said press forming has resulted in the formation a plurality of creases extending in a direction from the bottom portion to the top flange portion and further across the top flange portion, characterized in that the container comprises an indentation pattern formed at a creased inner surface of said sidewall portion and/or at a creased top surface of said top flange portion, said indentation pattern preventing migration of liquid from a liquid containing food product in the container along said creases, and to a method for manufacturing such container.

    Abstract: The invention concerns a fibrous-based oxygen barrier film, which comprises (i) a microfibrillated cellulose (MFC) film, (ii) an oxygen barrier polymer layer, (iii) an optional tie layer, and (iv) an outermost polyolefin layer. The invention even concerns a laminate, in which said multilayer film is combined with a fibrous paper or board base by means of an intermediate polyethylene layer. The oxygen barrier polymerlayer, which preferably is EVOH, and the polyolefin layer are brought by coextrusion onto the MFC film. The film and the laminate according to the invention aim at an improved oxygen barrier in high humidity conditions and have use in oxygen-sensitive food packaging.

    Abstract: The invention provides a biodegradable packaging materi- al, a method of manufacturing the same, as well as products made of the material. The manufacture comprises extrusion onto a fibrous substrate (1) one or more polymer coating layers including at least one layer (2) 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 ma- chine speed in extrusion and maintaining good adhesive- ness to the substrate and good heat-sealability of the coat- ing. The products include disposable drinking cups and board trays, as well as sealed carton packages for solids and liquids.
