摘要:
The coextruded multilayer film has at least two layers, including a sealant layer and a second layer in contact with the sealant layer. The sealant layer contains (A) a first ethylene-based polymer having a density from 0.865 g/cc to 0.930 g/cc and a melt index from 0.5 g/10 min to 25 g/10 min; (B) an unsaturated primary fatty acid amide having a melting point of 100° C. or less; and (C) a saturated primary fatty acid amide having a melting point greater than 100° C. The unsaturated primary fatty acid amide and the saturated primary fatty acid amide have a weight ratio of from 3:1 to 1:6. The second layer contains a second ethylene-based polymer. The present disclosure also provides a laminate containing said sealant layer.
