ABSTRACT:
The invention relates to a packing material in the form of a web intended for aseptic packages. The packing material is a laminate with the side of the packing material web which is intended to form the inside of the packages consisting of a thermoplastic layer, preferably polyethylene. This polyethylene layer has a sterile surface and is covered in turn by a thin plastic film which completely covers the polyethylene layer and maintains its sterility. On the conversion of the packing material to packages, the thin plastic film is separated from the surface-sterile polyethylene layer, whereupon the remaining packing material is formed to a tube which is filled with sterile contents so as to form closed packing units.
