Abstract:
1. A method for producing a package packaging a granular object having an adsorption ability, comprising the steps of: heating a granular object having an adsorption ability; charging the granular object into a storage bag having an end opening facing upward and an opposite closed end pressed flat; pressing flat to seal the end opening facing upward of the storage bag into which the granular object has been charged; cooling the storage bag with the granular object kept to be settled at a bottom pressed flat of the storage bag, and pressing an upper part of the storage bag where the granular object is not contained and a lower part of the storage bag where the granular object is settled, before the storage bag is sealed, so as to keep inner surfaces of the upper part without the granular object settled at the bottom of the storage bag into close contact with each other and to keep the granular object from moving when the sealed storage bag is cooled, wherein the step of heating is conducted prior to the step of sealing.
