APPARATUS FOR MANUFACTURING AND PROCESSING PRE-STRETCH FILMS HAVING STRIPS OF INCREASED THICKNESS
摘要
A method for maximizing a width of a pre-stretch film includes providing polymer being suitable for producing the pre-stretch film. A pre-stretch film having strips of increased thickness is produced. The method includes coordinating a thickness of the strips of increased thickness with a formation of edge thickening caused by neck-in during stretching of the pre-stretch film.
