    摘要: 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.

    摘要: The invention relates to a manufacturing method of a heat-sealable packaging material, a polymer-coated packaging material manufactured using the method, and a sealed package to be manufactured of the material. The packaging material comprises a fibre base, such as a packaging board (5), and an inner, extruded water vapour barrier layer (2, 9) on both sides, containing high-density polyethylene (HDPE), and an outer heat sealing layer (1, 10), the material of which is, for example, low-density polyethylene (LDPE). Further, polymeric oxygen barrier layers (7) can be incorporated in the packaging material, the material of the oxygen barrier layers being, for example, ethyl vinyl alcohol copolymer (EVOH) or polyamide (PA). With the HDPE layer, the permeation of water vapour is prevented to both directions, and the location of the extruded layers on both sides of the fibre base reduces the curling of the material. The packages according to the invention comprise carton, box and bag packages for dry and liquid foods.

    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).
