The present invention relates to a method for manufacturing of a laminated cellulose-based liquid or semi-liquid food packaging material, wherein the laminated packaging material has a bulk material layer of paper, paperboard or other cellulose-based material, an innermost, heat sealable and liquid-tight layer of a thermoplastic polymer, the innermost polymer layer intended to be in direct contact with the packaged food product, a barrier layer laminated between the bulk layer and the innermost layer. The invention further relates the laminated packaging materials obtained by the method and to a packaging container for liquid food packaging, comprising the laminated packaging material or being made from the laminated packaging material obtained by the method.

Laminated packaging material, packaging containers manufactured therefrom

The present invention relates to a method for manufacturing of a laminated cellulose-based liquid or semi-liquid food packaging material, wherein the laminated packaging material has a bulk material layer comprising a low-density cellulose spacer layer, an outside module comprising a substrate layer having a print surface and an inside material module comprising a barrier layer or barrier coating. The invention further relates the laminated packaging materials obtained by the method and to a packaging container for liquid food packaging, comprising the laminated packaging material or being made from the laminated packaging material obtained by the method.

Method of manufacturing a laminated packaging material, the packaging material obtained by the method and packaging containers manufactured therefrom

The present invention relates to a laminated liquid food packaging material, comprising a bulk layer of paper or carton or other cellulose-based material and outer layers of thermoplastic polymers on both sides, having a decorative 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.

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

The present invention relates to a method for manufacturing of a laminated cellulose-based liquid or semi-liquid food packaging material, wherein the laminated packaging material has a bulk material layer, wherein a further sheet is laminated to the bulk material layer by an aqueous adhesive composition. The invention further relates the laminated packaging materials obtained by the method and to a packaging container for liquid food packaging, comprising the laminated packaging material or being made from the laminated packaging material obtained by the method.

Method for manufacturing a laminated packaging material, the laminated packaging material and packaging containers made therefrom

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.

The present disclosure relates to a method for splicing a web of packaging material, comprising: guiding the web of packaging material through a splicing device comprising one or more imaging devices, a slitter, and a sealing unit; acquiring a first set of images of one or more areas of the packaging material, storing the acquired first set of images, slitting the web of packaging material in one or more locations to form a tail end and a head end of a web of packaging material, aligning the head end and the tail end and superimpose one on the other in preparation for forming a splice, utilizing the imaging devices and the stored acquired first set of images to fine tune the alignment of the head end and the tail end, sealing the splice.

Device and method for splicing

An arrangement for controlling longitudinal forces acting on a web of packaging material being wound from a first reel to a second reel, said arrangement comprising a first roller having a first rotational axis and a second roller having a second rotational axis, wherein the first rotational axis is fixed while the second rotational axis is movable.

Device for controlling tension in a web of packaging material

Device and method for controlling axial forces acting upon a moving web comprises first, second and third rotatable rollers. The third roller is between the first and second rollers and is movable in a circular path in the vertical plane between lower and upper positions in response to axial forces acting at any moment upon the web. To enable a simple manual installation of the web, the upper position of the third roller is at a sufficient vertical distance above the first and second rollers to form an open horizontal passage through which the web can pass freely between the first and second rollers and the above-situated third roller. Axial forces are controlled by biasing the third roller with a force which counters the motion of the third roller in the direction of the upper working position and which is less than the ultimate tensile strength of the web.

Device for controlling the web tension in a running material web

A printing system for printing a repeated pattern of esthetical and/or informative character on a substrate including a plurality of parallel webs is provided. The printing system comprises at least two overlapping non-impact printer units, each of which having a lateral elongation defining a maximum printing width, and a controller connected to each one of the printer units and configured to set an actual printing width extending between a start position and an end position of the lateral elongation, wherein the controller is configured to determine the actual printing width by receiving the lateral position of a non-printed area defined by the interface between two adjacent webs of the substrate and located laterally somewhere in the overlap between two printer units, such that the end position of a first printer unit and the start position of an overlapping printer unit is located within the non-printed area.

Printing system, and a method for printing

A packaging laminate for a retortable packaging container or carton, comprising a core layer () and outer, liquid-tight coatings (and) on both sides of the core layer (). The one () of the two outer coatings carries decorative artwork () of printing ink which is both mechanically and thermally protected by a layer () of lacquer applied on the coating () to make possible heat treatment at high humidity and temperature conditions of a packaging container produced from the packaging laminate (), without the printing ink decorative artwork of the packaging container deteriorating in quality.

Packaging laminate for a retortable packaging carton

The disclosure relates to a method of producing a well-integrated laminate material, for example a packaging laminate, in which method a first web () of plastic, and a second web () of plastic are brought together and permanently united to one another by the simultaneous application of heat and pressure, for the formation of the laminate material (). In order to improve the adhesion between the webs (and), these are subjected to a surface-activating treatment of non-chemical nature, preferably a corona treatment, prior to the uniting of the webs, whereby good adhesion and bonding between the webs is achieved without the employment of interjacent chemical adhesives. The method is preferably reduced into practice employing rollers (and) which are of different hardnesses, the relatively softer roller () being disposed to be movable in relation to the relatively harder roller () in such a manner that the nip between the rollers (and) through which both of the united webs are led may be adjusted at a suitable pressure, and that the nip obtains a certain width or extent in the linear direction of the webs as a result of the penetration of the relatively harder roller () into the surface of the compressing, relatively softer roller ().
