Abstract
A multilayer film having a first layer including a blend of a crystalline nylon and a material which disrupts the crystallinity of the crystalline nylon; a second layer also including this blend; and a third intervening layer, between the first and second layers, including a material having a modulus lower than the modulus of the crystalline nylon, and having a crystallinity of less than 60%. The nylon blend layers, which can be two or more in the film, add toughness and stiffness, but also elastic recovery to the final film. The intervening layer or layers of a material with relatively low modulus and crystallinity aid in orientation of the film during manufacture, permitting the use of more of the crystalline nylon than would be practical if only a single nylon layer was used.
