ABSTRACT:
A deodorizing coating formulation is composed of a white or substantially colorless deodorizing agent, a binder resin and a liquid medium. The deodorizing agent may preferably be composed of 10-90 parts by weight of a zinc compound and 90-10 parts by weight of an aliphatic polycarboxylic acid, aromatic polycarboxylic acid, acidic polymer or a sulfate of aluminum, or a salt thereof. A deodorizing sheet can be obtained by coating and/or impregnating a base sheet with the deodorizing coating formulation and then drying the resulting base sheet. The deodorizing sheet can shield a flavor or odor from external flavors or odors while maintaining air permeability, it is suitable for wrapping foods having strong flavors or odors.
