The present disclosure is directed to a process. In an embodiment, the process includes (A) providing a flexible container having (i) a body, and (ii) a neck. The process includes (B) positioning a fitment into the neck. The fitment is composed of a polymeric material and includes a top portion and a tapered base. The tapered base extends from the top portion to a base end. The top portion has a top inner diameter (TiD) and the base end has a base end inner diameter (BEiD). The BEiD is less than the top inner diameter, (TiD). The process includes (C) heating the tapered base to a malleable state and (D) inserting a mandrel into the fitment. The mandrel includes an expandable collar. The process includes (E) expanding the expandable collar radially outward to contact an inner surface of the tapered base. The process includes (F) increasing, with the expanding, the inner diameter of the base end to a stretched base end inner diameter (sBEiD). The sBEiD is greater than the BEiD. The process includes (G) sealing, with a pair of opposing seal bars, the tapered base to the neck.

A non-continuously laminated structure of thermoplastic films comprises thermoplastic films with differing material compositions and differing functional benefits. In particular, one or more embodiments comprise thermoplastic films that are co-extruded separately and then combined together by a post-extrusion bonding process. The differing composition of the various films of the non-continuously laminated structure of thermoplastic films and the post-extrusion bonding process, provide the structures with the functional benefits of the individual films.

A process comprises placing a first foamable material inside of a first region of a mold space, and a second foamable material inside of a second region of the mold space, the first foamable material and the second foamable material comprising a physical, chemical or quantitative difference or any combination thereof. Both the first and the second foamable materials are concurrently foamed inside of the mold space to produce a heterogeneous foam comprising a first portion that differs from the second portion.

A sealing device generally includes a rotatable support cylinder having an outer, circumferential surface and a heating element disposed about such surface and secured thereto such that the heating element rotates therewith. The heating element is coiled about the outer surface of the cylinder in the form of an overlapping helical pattern. Juxtaposed film plies may be sealed together by bringing the sealing device into rotational contact with the juxtaposed film plies and heating the heating element to a temperature sufficient to cause the film plies to seal together.

A method for sealing and cutting of a flexible material for forming a flexible container comprising a product volume and at least one structural support volume can include feeding at least two flexible material into a sealing apparatus comprising a sealing surface and an opposed anvil surface; contacting a seam region of the at least two flexible material with the sealing surface to form a seal in the seam region and cut the seal to form a seam in a single unit operation. The seal defines one or both of at least a portion of a boundary of the product volume and at least a portion of a boundary of the at least one structural support volume.
