ABSTRACT:
A method for forming a packing laminate and a packing laminate are disclosed. The disclosed method provides crack-resistant packing laminates which can be folded during the preparation of packing containers without the formation of excessive cracking due to tensile stresses. Tensile stresses within the folded laminated layers are reduced by either cutting portions of the laminate in an area corresponding to the fold line, or removing portions of the laminate corresponding to the fold line.
