Method for selecting adsorptive composite barriers for packaging applications

摘要

A method of selecting an appropriate resin bonded sorbent composition which may be used at least for in part making an enclosure to protect contents from external humidity including the steps of: a) selecting a plurality of resins, a plurality of sorbents and a plurality 5 of ratios therebetween to form a plurality of composites; b) calculating a plurality of failure times for the plurality of composites, wherein each failure time of the plurality of failure times is based on when an internal relative humidity of each composite of the plurality of composites is equal to the maximum internal relative humidity; c) determining which of the plurality of failure times is greater; and, d) selecting one composite of the plurality of 10 composites based on the result of step (c). An article of manufacture, comprising a resin bonded sorbent composition made according to the method, and a multi-layer barrier structure with at least one layer comprising a resin bonded sorbent composition made according to the method are also disclosed. 4240270_1 (GHMatters) P82102.AU.1
