ABSTRACT:
Blends having improved adhesion to each other when coextruded into multilayer films, such films, film-packages such as pouches from such films, and methods for making and using the films and film-packages are disclosed and claimed. Improved adhesion between layers results from adjusting the components of the blends of the layers. In addition, improved adhesion between layers results from reducing the temperature of the chill roll in the cast coextrusion process.
