COMPOSITION, MOLDED ARTICLE AND PACKAGING MATERIAL

摘要

PROBLEM TO BE SOLVED: To provide packaging materials and the like capable of reducing industrial wastes by disposing a large amount of extraction residues of natural organic substances produced by extracting necessary components from natural organic substances. SOLUTION: Packaging materials such as food trays containing extraction residues of natural organic substances such as used tea leaves and coffee extraction residues are formed. Since the packaging materials contain extraction residues of natural organic substances, a large amount of waste materials can be disposed by molding packaging materials to reduce the generation of industrial wastes. Further, it is possible to allow packaging materials to have properties such as deodorizing properties and preservation of freshness which the extraction residues of natural organic substances possess.
