  • Patent number: 6165610
    Abstract: Compared to a polyester film, films made from a blend of the polyester and up to 20 percent of an ethylene-acrylate copolymer have improved tear strength and heat seal strength while maintaining acceptable gloss, clarity, and coefficient of friction. The heat seal strength of the film and the bond strength of the film to aluminum vacuum deposited on the film are improved by adding less than five percent of an ethylene-acid copolymer to the blend.
