20090186135 | HEAT-SEALED STERILISED PRODUCT PACKAGE, PACKAGING MATERIAL FOR THE SAME AND USE OF THE PACKAGING MATERIAL - The invention relates to a polymer-coated heat-sealable packaging material, to a heat-sterilised package formed from this and to the use of the packaging material. The material comprises a fibre base | 07-23-2009 |
20090258119 | POLYMER-COATED LIQUID PACKAGING BOARD, A PACKAGE FORMED FROM IT AND THE USE OF THE POLYMER - The object of the invention is a liquid packaging board ( | 10-15-2009 |
20090324861 | POLYMER-COATED HEAT-SEALABLE PACKAGING MATERIAL AND A SEALED PACKAGE MANUFACTURED THEREOF - The invention relates to a heat-sealable packaging material and a sealed package formed from the same, especially for packaging foodstuffs. The packaging material comprises a base layer of paper or board and polymeric heat-sealable layers on one side of the base layer or, preferably, on both sides thereof. According to the invention, at least two layers of ethylene vinyl alcohol copolymer (EVOH) with different fractions of ethylene monomer are arranged on the packaging material to provide an oxygen barrier. The layers can locate against each other without a tie layer between them. The heat-sealable polymer can be a polyolefin, and, in addition, other polymeric barrier layers can be incorporated into the material to improve its oxygen, fat and aroma tightness. | 12-31-2009 |
20130059088 | PRIMING AND COATING PROCESS - The invention relates to a method for priming a substrate by contacting the substrate with a primer fed from a primer source and depositing the primer on the substrate. Compared to other priming methods, the claimed priming gives better results because the deposition is carried out electrostatically. | 03-07-2013 |
20130071677 | HEAT-SEALABLE BIODEGRADABLE PACKAGING MATERIAL, A METHOD FOR ITS MANUFACTURE, AND A PRODUCT PACKAGE MADE FROM THE MATERIAL - A heat-sealable biodegradable packaging material, its manufacturing method and a product package formed thereof, where the packaging material comprises a fiber substrate, an inner polymeric coating layer against the fiber substrate, which contains polylactide and a biodegradable polyester that is blended therewith to improve the adhesion between the inner coating layer and the fiber substrate, and an outer coating layer that constitutes the outer surface of the material and contains polylactide and a biodegradable polyester that is blended therewith to improve the heat sealing ability of the layer, the portion of polylactide in the inner layer than that in the outer layer. The inner and/or outer coating layers can further have blended therewith a small amount of acrylic copolymer that improves the adhesion and/or heat sealing ability. The coating layers can be introduced onto the fiber substrate by extrusion or coextrusion. | 03-21-2013 |
20130137562 | METHOD FOR IMPROVING THE HEAT SEALABILITY OF PACKAGING MATERIAL AND METHOD FOR MANUFACTURING HEAT-SEALED CONTAINER OR PACKAGE - A method for improving the heat sealability of a packaging material and a method for manufacturing a heat-sealed container or package are described. The material can be polymer-coated packaging paper or cardboard, or a polymeric packaging film. The material includes a polymer layer that contains polyester, particularly polylactide, the heat sealability of which is improved by ultraviolet radiation. Polylactide is useful as such or when blended, for example, with other biodegradable polyester. The containers and packages thus manufactured include disposable drinking cups and cardboard carton and box packages. | 05-30-2013 |
20130193026 | POLYMER-COATED OVEN BOARD AND FOOD PACKAGE MADE FROM IT - The invention relates to polymer-coated oven board and a closed oxygen impermeable food package formed from it. According to the invention, the coating on the board ( | 08-01-2013 |
20140099502 | HEAT-SEALABLE BIODEGRADABLE PACKAGING MATERIAL, A PACKAGE MADE THEREOF, AND USE OF A RESIN IN EXTRUSION COATING - The invention concerns a heat-sealable biodegradable packaging material, which comprises a fibrous substrate and one or more polymer coating layers extruded onto said substrate. According to the invention the packaging material includes at least one polymer coating layer containing polylactide and at least about 1 weight-% of terpene phenolic resin blended therewith. The invention further concerns a heat-sealed product package made from the packaging material, as well as uses of the resin as blends with polylactide in extrusion coating, for improving line speed and neck-in in extrusion, adhesivity of the coating to the fibrous substrate, and heat-sealability of the coating. | 04-10-2014 |
20140147604 | HEAT-SEALABLE BIODEGRADABLE PACKAGING MATERIAL, A PACKAGE OR A CONTAINER MADE THEREOF, AND USE OF A RESIN IN EXTRUSION COATING - The invention concerns a heat-sealable biodegradable packaging material, which comprises a fibrous substrate ( | 05-29-2014 |
