The invention relates to a method of manufacturing a new low density foam-formed cellulose material comprising dialcohol-modified celllulose, and to bulk sheets, layers, laminates or moulded articles comprising such material. Furthermore, the invention relates to a laminated packaging material comprising a layer or sheet comprising the low density cellulose material as well as to packaging containers comprising the laminated packaging material. In particular, the invention relates to packaging containers intended for liquid or semi-liquid food packaging, comprising the laminated packaging material.

Method of manufacturing of a foam-formed cellulosic fibre material, sheet and laminated packaging material

The present invention relates to a laminated cellulose-based liquid or semi-liquid food packaging material, comprising a bulk layer from cellulose fluting material, an outside substrate layer having a print surface and on the inside an aluminium foil barrier and a further barrier layer. The invention further relates to the method for manufacturing the laminated packaging material and to a packaging container for liquid food packaging, comprising the laminated packaging material.

Laminated packaging material, packaging containers manufactured therefrom and a method for manufacturing the laminate material

Described herein are laminated packaging materials comprising foamed cellulose, their use in manufacturing packaging containers, for use in packaging of food products.

Packaging material and packaging container

The present invention relates to a laminated liquid food packaging material, comprising a cellulose-based bulk material layer and outer layers of thermoplastic polymers on both sides, having a d&#xe9;corative print pattern arranged beneath one of the outer thermoplastic polymer layers. The invention further relates to the method for manufacturing the laminated packaging material and to a packaging container for liquid food packaging, comprising the laminated packaging material.

A laminated packaging material for food packaging, comprises a core layer of paper or paperboard, which on a first side intended to be directed towards the outside of a packaging container, has, in the following order, a dry pre-coating for receiving a printed d&#xe9;cor of an aqueous, pigment-based, ink-jet printing ink, a pigment-based ink-jet printed ink d&#xe9;cor layer and further laminated onto the printed d&#xe9;cor layer, a protective outermost layer of a thermoplastic polymer. Also disclosed is a method for manufacturing of the packaging laminate and to a packaging container that is made from the laminated packaging material as well as to a pre-coating composition for use in the laminated packaging material and in the manufacturing thereof.

Printed packaging laminate, method for manufacturing of the packaging laminate and packaging container

A lamination station for laminating a film to a web of paperboard includes a nip roller and a cooling roller. Between the rollers there is formed a nip which presses together the film and the web of paperboard with an interjacent molten polymer layer or adhesive layer disposed between the film and the web of paperboard. The film, the paperboard and the molten polymer lie, after the nip, in abutment against the cooling roller for a certain angle interval. The nip roller is a shoe-press type roller, either comprising a pressure bar having several hydraulically operated pressure elements, or comprising one or several rigid pressure bars.
