Metallisierte durchlässige Folien, hergestellt aus schmelzgeprägten Polyolefin/Füllstoff-Ausgangsfolien.

摘要

A breathable metallized polyolefin film is prepared by: melt embossing a highly filled polyolefin film to impose a pattern of different film thickness therein; stretching the melt embossed film to impart greater permeability in the areas of reduced thickness in comparison to the areas of greater thickness; and coating the resulting stretched embossed film with a suitable metal.
