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 .
