Abstract: An ion exchange resin membrane or an ion exchange precursor resin membrane having a thickness of 25 microns or less and having an orientation ratio of 1.5 or less; which may be produced by co-extruding an ion exchange precursor resin with an incompatible polymer to form a multilayer film having a layer of the ion exchange precursor resin supported on a layer of the incompatible polymer. The layer of incompatible polymer is then removed from the layer of ion exchange precursor resin to provide the ion exchange precursor resin membrane. The ion exchange precursor resin membrane may be converted to an ion exchange resin membrane by hydrolysis, and subsequent acidification if desired.

The ion exchange precursor resin membrane may be converted to an ion exchange resin membrane by hydrolysis, and subsequent acidification if desired. Ion exchange resin membranes and ion exchange precursor resin membranes having a uniform thickness of 25 microns or less may be formed by the process.

Abstract: A packaging structure for packaging an object. The packaging structure includes an object receiving portion for receiving the object at least partially thereinto. A retaining assembly is provided for selectively retaining the object within the object receiving portion. The retaining assembly is operable between a non-retaining and a retaining configuration wherein the retaining assembly respectively allows and prevents removal of the object from the object receiving portion. A lock releasably locks the retaining assembly in the retaining configuration. The lock is operable between a locked configuration and a non-locked configuration for respectively selectively locking the retaining assembly in the retaining configuration and allowing the retaining assembly to be moved to the non-retaining configuration. The lock includes a puzzle that allows the lock to be operated from the locked configuration to the unlocked configuration upon the puzzle being solved.

Abstract: The present invention relates to a process using dynamic high-pressure for inactivation of food pathogens. Liquid food are treated by dynamic-high-pressure at 1 to 5 kbars with at least one recirculation depending on the needs. The pasteurization process is performed at relatively cold temperature ranging from 4° C. to 55° C.
