Abstract
The present disclosure relates to multilayer thermoplastic films particularly suited for use in liners. The films contain organic fillers to produce opacity when stretched while maintaining an MD Tear Strength of at least 200 gm and a Dart Impact of at least 200 gm. Such performance can be maintained by selection and amounts of resins, organic fillers and processing conditions of the films.
