Abstract
The present disclosure provides a flexible container. In an embodiment, a flexible container is provided and includes a first multilayer film and a second multilayer film. Each multilayer film has 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. An orifice is present in one of the multilayer films. The flexible container includes an extendable spout extending through the orifice. The extendable spout has a flange sealed to the inner seal layer of the multilayer film at the orifice. The extendable spout is composed of, or is otherwise formed from, an ethylene/α-olefin multi-block copolymer.
