    Abstract: A polymeric composition includes a resin including an ethylene-based polymer and a copolymer of ethylene and an alpha olefin comonomer. The resin has a High Mw Comonomer Content of 3.2 wt % or greater based on a total weight of the resin over the weight average molecular weight range of 105 g/mol to 105.5 g/mol as measured by Ethylene GPC. The polymeric composition has a Relevant Comonomer Content of 0.6 wt % or greater. The polymeric composition also includes at least one of (i) a polydimethylsiloxane having a weight average molecular weight of 550,000 g/mol to 650,000 g/mol as measured according to Component GPC and (ii) a polymeric ultraviolet light stabilizer comprising a hindered amine moiety and having a weight average molecular weight from 5,000 g/mol to 20,000 g/mol as measured according to Component GPC.

    Abstract: The present disclosure provides a fabric laminate. In an embodiment, the fabric laminate includes a fabric sheet, a coating layer, and a tie layer. The fabric sheet is composed of propylene-based polymer fibers. The coating layer is composed of one or more ethylene-based polymers. The tie layer is located between the fabric sheet and the coating layer. The tie layer is composed of at least 50 wt % of a crystalline block composite (CBC) and an optional blend component. The CBC includes (i) an isotactic crystalline propylene homopolymer (iPP); (ii) an ethylene/propylene copolymer; and (iii) a diblock with the formula (EP)-(iPP). The CBC has a block composite index (CBCI) from 0.1 to 1.0. The fabric laminate has a peel force from 20 N/15 mm to 40 N/15 mm.
