Hot Fill Plastic Bottles

Styles of Hot Fill Plastic Bottles

Besides glass, Kaufman Container offers mainly two types of hot fill plastic bottles. Polypropylene (PP) bottles and hot fill PET plastic bottles. Polypropylene plastic bottles naturally allow for a high fill temperature typically to 205 degrees Fahrenheit. Our 32 oz, 64 oz and 1 gallon hot fill plastic jugs are made from polypropylene and are frequently used for bulk food products such as salsas and sauces.

Unlike Polypropylene, PET plastic is not designed for high fill temperatures and in order for them to be effective, a specific resin and process are required. A heat set resin is used and then is blown into a hot mold on a heat set machine specifically set up for PET. This provides the heat resistance necessary so the bottle will not deform from the hot liquids being filled. Hot Fill PET Plastic bottles typically can be filled up to 185 degrees Fahrenheit, but testing is always recommended to see if it will work for your product. Our most popular Hot fill PET plastic bottles include our 12 oz ring neck bottle and our 16 oz PET plastic decanter.
