REDUCTION OF RADIATION DAMAGE TO POLYMERS

Title:

REDUCTION OF RADIATION DAMAGE TO POLYMERS

Document Type and Number:

WIPO Patent Application WO2004072164

Kind Code:

A3

Abstract:

A film resistant to degradation caused by sterilising radiation is made. The film is made by minimizing the production of free radicals in the polymer (2 in Figure) during sterilization via the use of inert gas and reactant scavenger (6 and 8 in Figure), both within a sterilizable pouch. The scavengers can be acid adsorbents that react after sterilization. The films retain their physical and mechanical properties during storage and are useful for packaging pharmaceutical, food, semiconductor and medical products.
