Abstract

A method for making a vacuum packaging film includes flowing a plastic melt, from a multi-layer extruder (302), onto a rotating roller (308). The plastic melt is then cooled while simultaneously imparting a pattern, via a pattern imparting means, onto the plastic melt resulting in the vacuum packaging film.
