<p>PROBLEM TO BE SOLVED: To achieve superior smell volatilization preventiveness and biodegradation by adding a lactic acid resin composition having a lactic acid monomeric unit in its molecule and a specific rate of the content of a lactic acid monomer in a package body that can prevent smell in the package from leaking during seal-packaging of a smelly article. SOLUTION: A package body capable of preventing the smell of a smelly article in the package from leaking outside is formed of matter containing a lactic acid resin composition having a lactic acid monomeric unit in its molecule and a content of the lactic acid monomer of 50 wt.% or more. Such a smelly article includes matter that emits a strong smell of attendant bad influence causing unpleasantness, nausea or the like, stimulating the mucous membrane of the eye and nose, and adsorbing and transfering to the cloth or body, and, there are given the dirt of men and beasts, raw fish, pickles such as pickled radish, Korean pickles or the like as well as drugs and quasi- drugs. Also, for such a lactic acid resin used, there are given polylactic acid and a block copolymer with polylactic acid and aliphatic polyhydroxycarboxylic acid except polylactic acid.</p> |
