<P>PROBLEM TO BE SOLVED: To secure stable moldability without occurrence of a pinhole, breaking or the like of aluminum foil being a barrier layer even during cold molding of a forming depth or every mold shape, in a cold-forming packaging material used for a press-through pack wherein high dampproofness, barrier properties, light shielding properties, pinking resistance, and pinhole resistance are required. <P>SOLUTION: This cold-forming press-through pack packaging material uses, as a main base material, a biaxially stretched nylon film adjusted such that both the static friction coefficient and the kinetic friction coefficient are 0.30 or below, that breaking strength of all of four directions in a uniaxial tension test is 270 MPa or above, and that the 50% modulus value is 140 MPa or above. <P>COPYRIGHT: (C)2012,JPO&INPIT |
