摘要

Resistant but tear-resistant sheet, specially designed for the manufacture of containers, characterized in that it consists of at least three component sheets firmly adhered to each other, the middle of which is a micro-corrugated cardboard core; the outer one is constituted by a sheet of paper or thin cardboard, capable of receiving printing, and the inner sheet being a sheet of fibrous material, preferably reinforced paper, very resistant to breakage, it being foreseen to practice exclusively on this last sheet two parallel cuts of scarce separation between them delimiting a stripper strip, with the particularity that this band is constituted in the cutter element by the same planned and controlled line of the other two sheets, so that the stripped strip is composed of the three layers.
