Abstract
A multilayer film having coextruded layers comprising a znLLDPE-based core layer, and mLLDPE-based outer layers on each side of the core layer comprising, wherein the znLLDPE of the core layer has a density which is less than 0.005 g/cc different from a density of the mLLDPE of the outer layers, and wherein the znLLDPE of the core layer has a melting temperature which is less than 15° C. different from a melting temperature of the mLLDPE of the outer layers.
Claims20
A coextruded film comprising:
- a znLLDPE-based core layer comprising at least about 50 wt. % znLLDPE;
- and
- mLLDPE-based outer layers on each side of the core layer, wherein the outer layers consist of mLLDPE and no more than 2 wt % additives;
- wherein the znLLDPE of the core layer has a density which is less than 0.005 g/cc different from a density of the mLLDPE of the outer layers;
- wherein the znLLDPE of the core layer has a melting temperature which is less than 15° C. different from a melting temperature of the mLLDPE of the outer layers;
- and
- wherein the film has an overall thickness which is between 5 and 200 microns.
