Abstract
The invention relates to a method for the manufacture of a printed, pre-creased, plastic-coated packing material web provided with opening arrangements. The method includes providing a first wider web of paper or cardboard, whose width is a multiple of the desired packing material webs, with impressed crease line patterns and opening arrangements, whereupon the paper or cardboard web is covered with plastics. The wider web so treated is then cut into a number of partial webs, each partial web is of a width corresponding to the width of a complete crease line pattern. The partial webs are rolled up into large rolls intended for transport which in a separate printing operation are provided with text and decoration and are rolled up into magazine rolls of packing material of the desired size.
