Abstract

A method reclaims metalized polymer film or mixtures containing metal and/or metal alloys into a metal-containing, polymeric film. The resulting film structure has better oxygen and moisture barrier properties when metalized than plain metalized polymer films. The polymer to be reclaimed, originates in sheet form, and is densified, as by shredding, pelletizing and/or re-extruding into fine particulate form such as chips or pellets. The reclaimed polymeric film can be used, in a range of concentrations, to produce biaxially oriented polyester film for metalizing.
