ABSTRACT:
An improved polymer film material for the packaging of perishable foodstuffs, wherein the surface structure of the polymer is altered by means of an ion bombardment process so as to reduce the rates of transport of oxygen and water vapor through the polymer material wherein the polymer film material is produced by subjecting at least one surface of the film to ion bombardment with ions selected from the group consisting of hydrogen, carbon, nitrogen, helium, and argon at energies of 30-80 KeV and ion doses in the range of 10.sup.12 to 10.sup.18 ions/cm.sup.2.
