Abstract: The invention relates to a heat-sealable packaging material comprising: a paperboard substrate comprising a first side and a second side, a first coating layer on the first side, a first barrier coating layer on the first coating layer, which first barrier coating layer comprises pigments, a second coating layer on the second side, and a second barrier coating layer on the second coating layer, which second barrier coating layer comprises pigments, wherein the coating layers and the barrier coating layers comprise a latex or a water-soluble polymer, wherein the first coating layer and the second coating layer are free of pigments, wherein the first barrier coating layer and the second barrier coating layer comprise pigments in an amount in a range from >40 wt % to <70 wt %, based on the dry solid content of the respective layer, and wherein the grammage of each of the first and second coating layer and of the first and second barrier coating layer is in a range from >1 g/m2 to <10 g/m2.

Abstract: The invention discloses a method for producing a packaging material and a packaging material suitable for packaging of food and/or liquid. In the method of the invention a first barrier layer, and an optional second barrier layer, is applied on a first side of a paperboard web. The thereby formed barrier coated web is at least partly dried in a first drying step, whereupon an extruded layer is applied onto the partly dried barrier coated web in a second coating step. In accordance with the invention, the first and second coating steps are applied integrated within the same coating line. The application of a first barrier layer and an extrusion coated layer in the same coating line in accordance with the invention has shown to give rise to a packaging material with remarkably good barrier properties, especially gas-, liquid and/or grease barrier properties, for the packaging of food and/or liquid.

Abstract: The invention discloses a paperboard for packaging of a heat-sealable packaging material comprising: —a paperboard substrate comprising a first and a second side, —a first and an optional second dispersion coating layer on the first side, which first and optional second dispersion coating layer provides a barrier against at least one of liquid, moisture, grease and gas, —an extrusion coated barrier layer comprising a polyolefin, wherein the first and optional second dispersion coating layer is applied between the paperboard substrate and the extrusion coated barrier layer, and wherein the coat weight of the extrusion coated barrier layer is less than 15 gsm. The packaging material according of the invention minimizes the amount of plastic coating, but still provides the needed barrier properties for the packaging of food and/or liquid. The packaging material has especially been shown to provide a longer shelf life for food items packed in a packaging made from the material.

Abstract: The present invention discloses a paperboard for packaging of liquid and frozen food, comprising a dispersion coating as the only barrier layer on its outside/print side. It has surprisingly been found that a dispersion coating comprising latex and pigment applied on the outside/print side of a paperboard for liquid and/or frozen food may serve as the only barrier against moisture arising from condensation.

Abstract: The invention relates to a heat-sealable paperboard comprising a paperboard substrate (1) comprising a first side and a second side, a first dispersion coating layer (2) on the first side of the paperboard substrate (1), and a second dispersion coating layer (3) on the first dispersion coating layer (2), wherein the first dispersion coating layer (2) comprises a latex and pigment and the second dispersion coating layer (3) comprises a polyolefin.

Abstract: The invention relates to a packaging material comprising: a paperboard substrate comprising a first and a second side, at least one barrier layer applied on the first side of the substrate, the barrier layer comprising a water-soluble polymer selected from the group of polyvinyl alcohol, a copolymer of ethylene and polyvinyl alcohol, starch, carboxymethylcellulose and combinations thereof in an amount of at least 50 weight %, based on the dry weight of the barrier layer, an extrusion coated layer of a polyolefin on the barrier layer, and at least one dispersion barrier layer applied on the second side of the substrate, which at least one dispersion barrier layer forms a printing surface of the packaging material. The invention further relates to a method of manufacturing a respective packaging material.

Abstract: An inner drive for a magnetic drive pump includes a magnet supported on a yoke. The inner drive is driven about an axis to pump a corrosive process fluid. The magnet and yoke are fully encapsulated during the molding process to completely surround the magnet and yoke in a protective plastic shell. A sleeve is arranged radially outwardly of the magnet to provide further protection. Backing rings are arranged on either side of the magnet. A bonding material joins the plastic shell to the backing rings and sleeve to prevent a space from forming beneath the plastic shell that would become filled with the process fluid once it has permeated the plastic shell. A protective coating is arranged on at least a portion of the magnet to further insulate the magnet from the process fluid.
