Abstract
PURPOSE:To obtain the title film which prevents foods, drugs, etc., from being denaturated, containing a porous reduced material. CONSTITUTION:0.1wt.% or below nonferrous catalyst (e.g., fumic acid) is added to a porous material (e.g., activated carbon) having a particle diameter <=200 mesh and 2-2,800Angstrom pores and the mixture is reduced by heating to 150 deg.C or above under exclusion of air. The product is ground to obtain a porous reduced material. 1wt.% said porous material is added to a resin such as PE or PP, and the mixture is molded into a film.
