INFORMATION CARD

摘要

PURPOSE:To enhance heat resistance by forming the basic material for a card of a mixture resin of isopolypropylene polymerized using a multi-site catalyst and syndiotactic polypropylene polymerized using a single-site catalyst. CONSTITUTION:In the inventive information card, the basic material 2 for card provided with an information containing section (IC module 1) is formed of a mixture resin of isotactic polypropylene polymerized using a multi-site catalyst and a syndiotactic polypropylene polymerized using a single-site catalyst. In this regard, the flexural modulus of mixed polypropylene resin is set in the range of 11000-15000kg/cm<2>. The mixing ratio of isotactic polypropylene and syndiotactic polypropylene is set in the range of 50:50-80:20 wt.%.
