Abstract: The present disclosure is directed to a retort pouch. In an embodiment, the retort pouch includes a multilayer film with at least three layers. The at least three layers include (A) a skin layer comprising a blend of a propylene-based polymer and a styrenic block copolymer, (B) a seal layer comprising blend of a propylene-based polymer and a styrenic block copolymer, and (C) a core layer located between the skin layer (A) and the seal layer (B). The core layer comprises a blend of (1) a propylene-based polymer, (2) an ethylene-based polymer, and (3) a crystalline block composite (CBC).
