Abstract
Polymeric films having at least one outer layer consisting of a blend of low density polyethylene and a poly-(alkylstyrene) can be heat sealed to non-woven webs such as paper to produce peel openable packages, for example for medical equipment. Such packages can be peeled open with low fiber lift from the non-woven webs.
