DRYING AGENT COMPOSITION, DRYING AGENT-MOLDED PRODUCT, METHOD FOR CONTROLLING EQUILIBRIUM HUMIDITY AND METHOD FOR CONTROLLING TIME FOR MAINTAINING EQUILIBRIUM HUMIDITY

摘要

PPROBLEM TO BE SOLVED: To provide a drying agent composition prepared by mixing and kneading a drying agent with a thermoplastic resin, and a technique for expressing different equilibrium humidity by varying specific gravity of the resin even in the same species of the resin in a drying agent-molded product and easily forming preservation environment suitable for diversified goods. PSOLUTION: In the drying agent composition prepared by mixing and kneading the drying agent with the thermoplastic resin, the drying agent is mixed and kneaded to have 1-40 m secondary particle size in dispersing the drying agent, and the drying agent composition is obtained by selecting the specific gravity of the thermoplastic resin to control the equilibrium humidity.
