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.
