Abstract (en)
[origin: WO2008112024A1] A container comprises a micro cellular foamed polymer, and a non- reactive gas contained within the micro cellular foam cells, wherein the container has a non-transparent appearance. The process for making the container comprises injection molding a polymer preform having a non-reactive gas entrapped within the walls thereof, cooling the preform to a temperature below the polymer softening temperature, reheating the preform to a temperature above the polymer softening temperature, and blow molding the preform, to prepare a container comprising a micro cellular foamed polymer having a non-reactive gas contained within the micro cellular foam cells.
