BIAXIALLY ORIENTED POLYETHYLENE FILM WITH IMPROVED OPTICS AND SEALABILITY PROPERTIES

摘要

Methods of preparaing biaxially oriented polyethylene films with improved optics and sealability properties are provided. The methods include stretchi ng in the machine direction a multi-layer base sheet having a core layer with a first and a second side, at least one skin layer and outer surfaces; then coating at least one of the outer surfaces with a resin selected from the group consisting of low density polyethylene, very low density polyethylene, linear low density polyethylene and blends thereof; and finally, stretching the base sheet in a direction transverse to the machine direction.
