Abstract
Flexible, halogen-free films, both multilayer films and monolayer films, can replace polyvinyl chloride films in applications requiring high speed welding by high frequency radiation. The monolayer films result from a blend of a non-polar olefin polymer and a polar olefin polymer that contains carbon monoxide. The multilayer films have like that of the monolayer films, but located so as to promote high frequency sealing. Products made from such films are particularly well suited for medical device applications.
