Abstract

The present disclosure provides a flexible container. In an embodiment, the flexible container includes a first multilayer film and a second multilayer film. Each multilayer film comprises an inner seal layer. The multilayer films are arranged such that the seal layers oppose each other and the second multilayer film is superimposed on the first multilayer film. The multilayer films are sealed along a common peripheral edge. The flexible container includes an orifice in one of the multilayer films, and a pop-up spout extends through the orifice. The pop-up spout has a flange sealed to the multilayer film around the orifice. The pop-up spout comprises an ethylene/α-olefin multi-block copolymer.
