Question
We currently use glass bottles, but want to convert to plastic bottles due to the weight in shipping glass. I am having trouble locating a plastic bottle that will with stand the 185 degrees required when filling without loosing shape. Any help would be much appreciated.

Answer
There are heat resistant plastic bottles, usually made of polyester or polypropylene. They need to be heavy enough to resist distortion in hot filling. They often have special designs, such as rings at the top to hold while applying the cap. Owens Illinois makes both glass and plastic bottles. You have to control filling temperature carefully, because a few degrees matter. With glass, it is easy to exceed the target temperature because it matters less, but with plastic, it matters a lot.
