  • Publication number: 20190366695
    Abstract: A multilayer cast film includes a cling layer, a release layer, and at least one core layer disposed between and contacting the cling layer and the release layer. The cling layer includes an ultra low density polyethylene (ULDPE), a propylene interpolymer, or blends thereof. The release layer includes a first linear low density polyethylene (first LLDPE) having a density of from 0.915 to 0.938 g/cc and a melt index of from 0.5 g/10 min to 10 g/10 min. Each of the core layers includes a second linear low density polyethylene (second LLDPE) having a density of from 0.905 to 0.930 g/cc and a melt index of from 0.5 g/10 min to 10 g/10 min. The multilayer cast film includes from 3 wt % to 7 wt %, based on a total amount of polymers present in the multilayer cast film, of the low density polyethylene (LDPE).

  • Patent number: 10315395
    Abstract: Disclosed herein is a multilayered article comprising a core layer comprising a thermoplastic polymer; where the thermoplastic polymer comprises a polyolefin, thermoplastic starch, and a compatibilizer; where the compatibilizer does not contain ethylene acrylic acid; where the polyolefin is not polypropylene and where the polyolefin present in an amount of greater than 40 wt %, based on a total weight of the core layer; a first layer comprising a thermoplastic resin; and a second layer comprising a thermoplastic resin; where the first layer and the second layer are devoid of fillers; where the first layer is disposed on a side of the core layer that is opposed to the side that contacts the second layer; where the multilayered article has an optical clarity of greater than 80% when measured as per ASTM D 1746 and a total haze less than 8% when measured as per ASTM D 1003.
