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： Method of manufacturing polymer-coated heat-sealable packaging material and sealed packages (e.g., carton, box, or bag packages for dry and liquid foods). The material includes a fiber base of packaging paper or packaging board, an outer polymeric heat sealing layer such as LDPE, and an inner polymeric water vapor barrier layer which is partly or totally formed of an amorphous cycloolefin copolymer. In the method, the cycloolefin copolymer water vapor barrier and the heat sealing layers are brought onto the fiber base by an extrusion step, and in accordance with the manufacturing method, they can be placed on one side of the fiber base or on both sides of the fiber base for achieving a moisture barrier on both sides of the package. Also, polymeric oxygen barrier layers, such as EVOH or polyamide layers, can be incorporated into the packaging material. By using the cycloolefin copolymer as an extruded water vapor barrier layer, curling of the packaging material is prevented.

摘要： In a method for forming a package, a package with the shape of a container is formed of a cardboard blank, the package having a bottom and side walls extending upwards from the bottom. At the end stage of compression molding, a rim of molding material extending sideways is molded to the upper part of the side walls when the mold is kept closed in such a way that a mold cavity corresponding to the rim is formed by moving a counter surface inside the mold backwards from a surface opposite to it, after which the molding material is introduced into the mold cavity.
