MANUFACTURE OF HEAT-RESISTANT RESIN CONTAINER

摘要

PURPOSE:To provide the manufacturing method for a heat-resistant container easily and efficiently in a short time regardless of its wall thickness by blow molding. CONSTITUTION:A molded product is obtained by infection molding using 100 pts.wt. of a resin composition that is composed of 1-100 pts.wt. of at least one kind at least one kind of polybutylene terephthal resin and 99-0 pts.wt. of at least one kind of polyethylene terephthalate resin at the temperature of its melting point or above. Said molded product is cooled down to the temperature lower than the crystallizing temperature and higher than its glass transition point, and it is blow molded in a mold, the temperature of which is adjusted to the temperature higher than its cooling crystallizing temperature and lower than the melting point of resin which is the lowest of all melting points of resins to be used for the purpose.
