PLASTIC BABY BOTTLES, OTHER BLOW MOLDED ARTICLES, AND PROCESSES FOR THEIR MANUFACTURE |
摘要 |
The invention is generally directed to baby bottles and other articles produced by blow molding from polymeric materials having glass transition temperatures ranging from 100° C. to 130° C., as well as to processes for producing them. These articles can be exposed to boiling water and can be produced by using a suitable combination of a stretch ratio of less than 3 and a preform temperature at least 20° C. greater than the glass transition temperature (Tg) of the polymeric material.
