METHOD OF SELECTING ABSORBING COMPOSITE BARRIERS FOR PACKAGES Russian patent published in 2011 - IPC B01J20/26 B01J20/02 

FIELD: process engineering.

SUBSTANCE: invention relates to absorbing barrier materials. Proposed method of selecting suitable composition of resin-bound sorbent that may be used for at least partial production of envelope for protection against external moisture comprises the following stages: a) selection of multiple resins, multiple solid dispersed sorbents and multiple ratios of said materials, to produce multiple composites; b) calculation of multiple time intervals of destruction for multiple composites wherein every time interval of destruction is calculated when internal relative moisture content of every composite equals maximum internal moisture content; c) defining which time interval of destruction is larger; and d) selecting one composite from multiple composites proceeding from the result of stage (c).

EFFECT: improved moisture absorption properties.
