ABSTRACT:
Method and apparatus for the manufacture and stretching of a laminate comprising forming at least two laminates, which are stretched together in superposed relation, from at least four films so as to form a combination of laminates and subsequently peeling said combination to form separate laminates. A laminate prepared in this manner is advantageous in that one of its surfaces has a high smoothness evidenced by high gloss and a high coefficient of friction which makes the laminate particularly suitable for use in the production of high quality sacks.
