    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.

    Abstract: The present invention relates to a monolayer film comprising a mixture of a first linear polyethylene having a density in the range of from 0.926 to 0.970 g/cm3; a second LLDPE having a density in the range of from 0.868 to 0.920 g/cm3; and a nucleating agent to get to a better balance of low WVTR and dart while still allowing film production from it on standard monolayer equipment without need for co-extrusion capability. The LLDPE with the higher density is further characterized by having at least 57 percent (by weight of that component) of molecules having a weight average molecular weight in the range of 31,000 g/mole to 1,000,000 g/mole. These components are blended in various ratios ranging from 50 to 90% of the higher density LLDPE, 10 to 50% of the lower density LLDPE and at least 50 ppm of the nucleating agent.
