Are these bottles hot fill bottles ?

PET plastic has a maximum heat temperature of 176° Fahrenheit. Usually a good alternative with a higher max temperature is polypropene or PP plastic. A major advantage to PP containers is that they have a higher temperature resistance than HDPE containers, with a max temperature of 275° Fahrenheit, and a 32° Fahrenheit minimum temperature. Check out our blog post here about the different types of plastic. We highly recommend ordering samples prior to placing large orders, so you can test the bottles to your end use. The purchaser assumes all responsibility for testing the compatibility and capacity of their products with goods sold by TricorBraun.
