PROBLEM TO BE SOLVED: To provide an elastic film for diaper area, which is a continuing raw material base; and to provide a method for producing the same.SOLUTION: This invention relates to: an elastic film for diaper area, especially for an elastic diaper fastener element; and a method for producing the same. The film includes an elastic layer (1), which then is produced by extruding a polymer composition. The polymer composition contains a mixture of a styrene block copolymer with a softening agent. Over 50 wt.% of the softening agent, preferably the entire softening agent comprises at least one vegetable-based oil, especially a purified rapeseed oil.

PROBLEM TO BE SOLVED: To provide a packaging film that is well suited for packaging machinery using an automatic packaging machine, in which slackening does not occur during long-term low temperature storage and in which high-stretch packaging does not cause whitening of the film.SOLUTION: A stretch packaging film formed by a laminate film comprising at least three layers, wherein both surface layers contain an ethylene-based resin (A) component as a primary component, and an interlayer includes, a propylene-based resin (B) component satisfying following conditions (1) and (2) and a propylene-based resin (C) component satisfying a following condition (3), wherein the crystallization heat is 10-60 J/g, and the storage modulus is 100 MPa-1 GPa. (1) The peak of the crystallization curve when measured with DSC is a single. (2) The crystallization peak temperature in (1) is ≥70°C and a heat amount of crystallization is ≤10J/g. (3) The value of the heat amount of crystallization when measured at DSC has a value larger than the heat amount of crystallization of the propylene resin (B).

PROBLEM TO BE SOLVED: To provide a resin molded product capable of improving a biodegradable rate and electronic equipment using the molded product and to provide a method for treating the resin molded product in which biodegradable rate can be improved. SOLUTION: The resin molded product 10 comprises a molded base material 11 composed of a biodegradable resin, and a coated film 12 formed on the surface of the molded base material 11, wherein the coated film 12 comprises a petroleum-based coating material, a natural material and a proliferation promoter for promoting proliferation of microorganisms, e.g. a carbohydrate or an amino acid. The resin molded product 10 proliferates microorganisms in soil by the proliferation promoter and improves biodegradable rate of the resin molded product 10. COPYRIGHT: (C)2007,JPO&INPIT
