PROBLEM TO BE SOLVED: To obtain a molded product whose biodegradation power is promoted without increasing an amount of an additive for biodegradable resins, by molding a resin material wherein a specific amount of an inorganic anti-fungal agent is added to a resin to which a biodegradable resin additive has been added. SOLUTION: An inorganic anti-fungal agent in an amount of 0.1 to 3% is added. More particularly, there is a material blow-molded, in which 1.5% of an anti-fungal glass 'Ion Pure' (commercial name) (made by Ishizuka Glass Co., Ltd.), which is a kind of inorganic anti-fungal agent, is blended, for example, with a biodegradable resin made of a blend of 80% of an HDPE resin and 20% of a biodegradable resin additive 'Degra Novon (commercial name) (made by Novon International Inc.). The anti-fungal glass 'Pure Ion' is made of a combination of a glass composition having weak chemical durability and ionized silver/copper/zinc having fungicidal.mildewproofing properties. When water or moisture is present, these metal ions are released only in very small amounts, thereby exhibiting the fungicidal/mildewproofing properties.
