摘要： 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.

摘要： The invention relates to a polymer-coated Polymer-coated heat-sealable packaging material, heat-sterilized package formed from the material, and use of the packaging material. The material comprises a fiber base 4 (e.g., packaging board made of bleached pulp) with polymer heat-seal layers 1,9 located on both sides thereof. The package comprises, outside the fiber base, first polymer coating layer 2, which contains white pigment for covering the fiber base from sight, and second coating layer 8, which contains light-absorbing pigment. A coating layer pigmented grey inside the fiber base may provide a light shield for the packaged product. Absorbent black pigment may be located outside the fiber base underneath the white layer to stabilize the brightness of the material. A heat-sterilized package is made by providing the packaging material, forming a package containing, e.g., food, and heat-sterilizing the package in an autoclave. Yellowing of the fiber-based material is avoided by means of a white pigment.

摘要： The invention relates to a multi-layer heat-sealable packaging material especially for food packages. In addition, objects of the invention are a food package formed of the said packaging material, a method of packaging, and the use of the material for packages. The packaging material (1) comprises a middle layer (3) of fibre material, such as cardboard; at least one polymeric protective layer (4, 5) protecting the product from going bad; and polymeric heat sealing layers (2, 7) preferably on both sides of the packaging material. According to the invention, the heat sealing layer (7) forming the inner surface of the closed package, is blended with light-absorbing pigment, such as carbon black, for protecting the product from visible light. By further blending white pigment, such as titanium dioxide, into the heat sealing layer (7), a grey tint resembling an aluminium foil has been achieved for the layer. The heat sealing polymer may be low-density polyethylene (PE-LD), and an oxygen and aroma proof sealing layer (4) of, for example, ethylene vinyl alcohol copolymer (EVOH) or polyamide (PA) may be provided between it and the cardboard (3).

摘要： The object of the invention is a liquid packaging board (1), wherein the base board (3) is provided with at least one polymeric coating layer on both sides thereof to decrease the flavor scalping from a packaged liquid, such as citrus fruit juice. Inside the baseboard, there is a layer (6) of ethylene methyl acrylate copolymer either in a direct contact with the packaged liquid or coated with a thin layer of polyolefin. The invention also relates to a closed package for liquid food that is formed from the liquid packaging board (1) by folding and seaming, wherein the side that comes in contact with the food product, correspondingly, comprises an EMA layer and, possibly, a thin polyolefin layer on top of the same. The invention further comprises the use of EMA in decreasing the flavor scalping from the packaged liquid by the packaging material.
