摘要

Pressurizable thermoplastic containers, such as those made from polyethylene terephthalate containing a polyurethane layer on the exterior surface thereof are disclosed. The polyurethane layer which is typically applied by a coating process provides the bottle with resistance to stress cracking. The containers are useful as refillable bottles for carbonated beverages which have a tendency to stress crack.
