METHODS AND COMPOSITIONS FOR ON-DEMAND RELEASE OF CI02 GAS FROM UV-ACTIVATED CHLORITE ION

Compositions and methods for generating ClO.sub.2 gas are disclosed. A composition that includes a chlorite salt is activated by exposure to ultraviolet light. After an optional storage period, the composition is then exposed to moisture, resulting in the generation of ClO.sub.2 gas. Exemplary compositions include polymers in which the chlorite salt is dispersed. The polymers may be used to form films that can be used to package, e.g., food products, pharmaceutical products, medical devices, and/or laboratory devices. Upon exposure to ultraviolet light and moisture, the packaging releases controlled quantities of ClO.sub.2 gas, which may disinfect and/or deodorize the packaged device or product.

MULTILAYER FILM, PACKAGING MATERIAL AND PACKAGE

A multilayer film including a first outer layer containing 70 to 30% by mass of a propylene homopolymer (A) and 30 to 70% by mass of a propylene/ethylene random copolymer (B) having an ethylene content of 5% by mass or less, an inner layer containing a propylene/ethylene block copolymer (C) and an ethylene/propylene copolymer elastomer (D), and a second outer layer containing 70 to 30% by mass of the propylene homopolymer (A) and 30 to 70% by mass of the propylene/ethylene random copolymer (B) having an ethylene content of 5% by mass or less, in that order.

Flexible polymer-based material for hot isostatic pressing or warm isostatic pressing molds

There is disclosed a sealable, flexible membrane for encapsulating a part to be isostatically pressed at an elevated temperature. The membrane includes at least one first layer of polymeric film having a melting point above the elevated temperature, and at least one second layer disposed on the first layer. The second layer comprising a metal. In one embodiment, the metal comes into contact with the part to be isostatically pressed. The membrane, which typically has a thickness ranging from 10 to about 500 μm, and is impermeable to the flow of liquids and gases when sealed, can be used to warm press parts up to about 350° C. and pressures ranging from 5,000 psi to 100.000 psi. Methods to isostatically press parts using this sealable, flexible membrane are also disclosed. Bags made from the sealable, flexible membrane that are used in isostatic presses are also disclosed.
