    摘要: The present disclosure provides a process. In an embodiment, the process includes (A) providing a fitment with a base having a wall thickness (T w ). The base comprises an ethylene/a olefin multi-block copolymer. The process includes (B) placing the base between two opposing multilayer films. Each multilayer film has a respective seal layer comprising an olefin-based polymer. The process includes (C) positioning the base and opposing multilayer films between opposing seal bars. Each seal bar comprises (i) a front surface, (ii) a recessed surface a distance ( x ) behind the front surface, the recessed surface having a first end and an opposing second end. Each seal bar comprises (iii) a curved surface at each opposing end. The curved surface extends between the front surface and the recessed surface. Each curved surface has a radius of curvature (Rc) greater than or equal to distance ( x ). The process includes (D) heat sealing the base to each multilayer film.

    摘要: The present disclosure provides a container. In an embodiment, a flexible container (8) is provided and includes a first multilayer film (16) and a second multilayer film (18). Each multilayer film includes a seal layer. The multilayer films are arranged such that seal layers oppose each other and the second multilayer film is superimposed on the first multilayer film. The films are sealed along a common peripheral edge (20). The flexible container includes a fitment (10) having a base (12). The base (12) includes an ethylene/a-olefin multi-block copolymer. The flexible container includes a fitment seal (22) comprising the base located between the multilayer films. The base is sealed to each multilayer film at a portion of the common peripheral edge (20).
