ABSTRACT OF THE DISCLOSURE A novel composition of matter having surprising physical properties when fabricated into multiple layer films is disclosed. The composition is generally a blend of nylon 6 with a nylon copolymer comprised of nylon 6 and a second nylon copoly- mer. The second nylon polymer is 2.5 to 10 mole percent of the overall composition. The remaining 97.5% to 90% of the composi- tion is the nylon 6 and the nylon 6 component of the copolymer. The nylon composition may be comprised entirely of a nylon cop- olymer having 90% to 97.5% nylon 6 and 10% to 2.5% of a second nylon polymer. The multiple layer films fabricated with the nylon compositions show unexpected range of thermoforming and heat sealing capabilities and good heat resistance, similar to that of nylon 6.
