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).

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 (4), which is e.g. a packaging board made of bleached pulp, and polymer heat-seal layers (1, 9) located on both sides of this. In accordance with the invention, the package comprises, outside the fibre base, a polymer coating layer (2), which contains white pigment for covering the fibre base from sight, and a second coating layer (8), which contains light-absorbing pigment. A coating layer pigmented grey inside the fibre base, for instance, provides a light shield for the packaged product. The absorbent black pigment may also be located outside the fibre base underneath a white layer in order to stabilise the brightness of the material. The package may be e.g. a food package heat-sterilised in an autoclave, in which yellowing of the fibre-based material has been avoided by means of a white pigment.
