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.
