FILMS WITH IMPROVED DART IMPACT RESISTANCE |
| 摘要 |
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. |

1. A film comprising a polymer and at least one filler, said polymer comprising a polyethylene polymer having a density less than 0.970 g/cm3, a melting point less than 137° C., melt index between 0.1 dg/min to 5.0 dg/min; said filler is organic in composition and when dispersed in polyethylene has particle size d50 from 0.1 micron to 10 micron, particle size d90 less than 5 times d50, and said film has significantly higher dart impact strength and similar MD Tear strength and ultimate tensile strength when compared to a film without the organic filler. |
