PROBLEM TO BE SOLVED: To provide a water vapor and oxygen adsorptive resin pellet that solves the problem that when mixing into a polyolefin resin or polyester resin as a base resin, a silica powder it is difficult to obtain an efficacy as a desiccant because it is not possible to uniformly disperse and mix because of the light bulk density, and further it is difficult to obtain an efficacy as a deoxidizer because it is not possible to mix an amine compound.SOLUTION: The water vapor and oxygen adsorptive resin pellet is characterized in that to the total of 100% weight of a mixture obtained by blending and molding: a base resin comprising a polyolefin resin such as polyethylene or polypropylene, a polyester resin, a polystyrene resin, a polyvinylidene chloride resin, or a mixture thereof; a silica powder; and, as additives, a binder, a dispersant and a lubricant, said silica powder and an amine compound are melt-mixed into the base resin by 20% or more and by 25% or more, respectively. |
