    Abstract: The present invention provides resins for use as a sealant layer in a multilayer film, multilayer films, and packages formed from such films. In one aspect, a resin for use as a sealant layer in a multilayer film comprises (a) 10 to 30 weight percent low density polyethylene based on the total weight of the resin; (b) 60 weight percent or more of a random copolymer polypropylene based on the total weight of the resin; and (c) 5 to 25 weight percent of a crystalline block copolymer composite (CBC) comprising: i) a crystalline ethylene based polymer (CEP) comprising at least 90 mol % polymerized ethylene; ii) an alpha-olefin-based crystalline polymer (CAOP); and iii) a block copolymer comprising (1) a crystalline ethylene block (CEB) comprising at least 90 mol % polymerized ethylene and (2) a crystalline alpha-olefin block (CAOB).

    Abstract: A comprising includes one or more polyethylene, one or more polypropylene, one or more polyolefin elastomer, and a crystalline block composite having the following three components: (i) a crystalline ethylene based polymer, (ii) a crystalline propylene based polymer, and (iii) a block copolymer having a crystalline ethylene based block and a crystalline propylene block. The composition of component (i) is the same as the crystalline ethylene based block of the block copolymer and the composition of component (ii) is the same as the crystalline propylene block of the block copolymer. The composition is useful for forming rotomolded articles.
