Abstract:
PROBLEM TO BE SOLVED: To provide an oxygen absorbent multilayered film which shows high oxygen absorbability even if a usually added transition metal salt is not added as a catalyst for enhancing oxygen absorbability and brings about no offensive smell problem even after oxygen is absorbed, a packaging material comprising the oxygen absorbent multilayered film and a packaging container obtained by molding the packaging material. SOLUTION: The oxygen absorbent multilayered film has a thickness of below 250 μm and is constituted by laminating a gas barrier material layer, an oxygen absorbing agent layer and a hermetic sealing material layer in this order and the oxygen absorbing agent which constitutes the oxygen absorbing agent layer is based on a conjugated diene polymer cyclized material. The packaging material comprising the oxygen absorbent multilayered film and the packaging container obtained by molding the packaging material are also disclosed. COPYRIGHT: (C)2006,JPO&NCIPI
Abstract:
PROBLEM TO BE SOLVED: To provide a biaxially oriented polyester film which is excellent in gas barrier properties such as an oxygen gas barrier property, mechanical characteristics such as elastic modulus, gloss, printability, methylation, coatability, and winding characteristics, and at least whose one side has an excellent adhesion-promoting property for adhesiveness to other polymers, metals, and printing inks. SOLUTION: This biaxially oriented polyester film comprising a polyester and poly(m-xyleneadipamide) is characterized in that the elastic moduli of the polyester film are ≥3500 Nmm 2 in the longitudinal direction and in the lateral direction, respectively, and at least one side of the polyester film has an adhesion-promoting property.

Abstract:
PROBLEM TO BE SOLVED: To provide a biaxially stretched polyester film, which is excellent in mechanical properties such as elastic modulus, gloss, printability, metalization, coating applicability and winding property, producible at low cost and excellent in oxygen gas barrier property (oxygen gas transmittance: less than 1 cm 3 m -2 d -1 bar -1 ). SOLUTION: The biaxially drawn polyester film comprises a polyester and a poly(m-xylene adipamide). The elastic modulus of the polyester film is 3,500 Nmm 2 or higher in both longitudinal and lateral directions. The polyester film has a metal layer or a ceramic layer on at least one of its sides.
