摘要:
The objective of the present invention lies in providing a resin composition which enables water vapor permeability to be controlled over a broad range while maintaining a high gas permeability, together with molded articles or packaging materials comprising said composition, in particular a packaging material for foodstuffs like fruit and vegetables. A thermoplastic resin composition which is characterized in that a polymer (A) containing polyether chains as structural units, polyethylene (B) of density as specified in JIS K6760 of less than 0.91 g/cm3 and a compatibilizing agent (C) are blended together in proportions by weight of A/B/C=99.5 to 0.5/0.5 to 99.5/0 to 30 (where A+B+C=100); and molded articles comprising said composition, in particular a packaging material for vegetables and fruit cultivation or foodstuffs storage.
