Two-component adhesion composition suitable for extrusion coating paper substrates which comprises:

Adhesive propylene polymer composition suitable for extrusion coating of paper substrates

Two-component adhesion composition suitable for extrusion coating paper substrates comprising:

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(e.g., packaging board made of bleached pulp) with polymer heat-seal layerslocated on both sides thereof. The package comprises, outside the fiber base, first polymer coating layer, which contains white pigment for covering the fiber base from sight, and second coating layer, 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.

Method of making heat-sterilised product package

The present invention relates to a polymer composition with good chemical properties and barrier properties being multimodal and comprising a polymer (A) having a weight average molecular weight of lower than 6000 g/mol and a polyolefine (B) having a higher weight average molecular weight than polymer (A) and a filler (C), whereby a polymer composition without filter (C) has a density of 940 kg/mor lower.

Extrusion coating polyethylene

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 () comprises a middle layer () of fibre material, such as cardboard; at least one polymeric protective layer () protecting the product from going bad; and polymeric heat sealing layers () preferably on both sides of the packaging material. According to the invention, the heat sealing layer () 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 (), 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 () of, for example, ethylene vinyl alcohol copolymer (EVOH) or polyamide (PA) may be provided between it and the cardboard ().

Aluminum-colored multilayer heat-sealable packaging material

Extrusion coating structure in which at least one layer is made of a polymer composition comprising a multimodal ethylene polymer, which contains from 80 to 100% by weight of ethylene repeating u nits and from 0 to 20% by weight of C,-C,alpha-olefin repeating units, has a density of between 0.920 and 0.960 kg/m,, and which is a blend of at least two different ethylene polymers.
