Abstract
Improved polymer additive concentrate compositions used in nylon film layers. The improved concentrate comprises a carrier of a nylon polymer composition and the additive material. Preferred nylons include nylon 6; nylon 6,66; nylon 6,6; and combinations thereof. Preferred additives are antiblock agents and slip agents. The film layers may comprise a single layer nylon film, or may be part of a multiple layer composition. The films are susceptible to being used in making packaging.
