A manufacturing process for composite film for thermoformed products, including the steps of manufacturing a first plastic substrate film in the amorphous state, by extrusion, causing said first plastic substrate film to undergo a decoration/metal-finish process, causing said first plastic substrate film, to undergo a lamination step, characterized in that before said lamination step, on said first amorphous substrate film a layer of molten plastic material is laid, corning out of an extrusion head, and in that said first plastic film coupled with the layer of molten plastic material, immediately downstream of said extrusion head pass between an entry cylinder and a master cylinder of a lamination unit furthermore comprising at least an exit cylinder, the thickness of said first substrate film being in the range of 150-800μ and the thickness of said molten layer being in the range of 150-1200μ after lamination, said entry cylinder, master cylinder and exit cylinder being heat adjusted on temperatures in the range 20-55° C., with growing temperatures from the entry cylinder, to the master cylinder to the exit cylinder.

A system for carbonating a personalized beverage may comprise a base container including at least one sidewall defining a liquid storage area, and a carbon dioxide storage member configured to be sealingly coupled to said base container. The system may further comprise a carbon dioxide cartridge configured to selectively release carbon dioxide when engaged with said carbon dioxide storage member, and wherein said carbon dioxide storage member further comprises a pressure regulator configured to, when actuated, release the said carbon dioxide from said carbon dioxide cartridge at a rate configured to carbonate a beverage within said liquid storage over a period of time greater than 6 hours and less than 36 hours.

Multilayer Films have a first skin layer that is prepared from a high density polyethylene and a second skin layer (also referred to as the sealant layer) that is prepared from a linear low density polyethylene (LLDPE) having a density of from 0.90 to 0.92 g/cc and a Dilution Index, Yd, of greater than 0°. Seals can be prepared by placing two pieces of this film against each other such that the sealant layers are in contact with each other, then applying heat to at least one high density skin layer such that heat is transmitted/conducted through the multilayer film in a sufficient amount to melt the sealant layer and form a seal. The use of LLDPE having a Dilution Index of greater than 0° has been found to improve the sealing performance of multilayer films in comparison to multilayer films where the sealant layer is a conventional LLDPE having a Dilution Index of less than 0°.

A fabric and elastomeric material (referred to as a fabric trilayer) combined with a sealant may be applied in such a fashion so as to eliminate or minimize air entrapment in an elastomeric composite structure that forms a seal-sealing volume. The performance of the self-sealing volume is dramatically improved with this minimizing of air entrapment. Surprisingly and unexpectedly, this construction approach may be accomplished without significantly adding to the weight or thickness of the volume and without affecting the outer dimension of the self-sealing volume. Thus, a method and system for forming a self-sealing volume are described. The system includes an elastomeric composite structure comprising at least one layer of an elastomeric material derived from a neat (no solvent) elastomeric material that does not substantially react at room temperature.
