Does My Product Need to be Hot Filled?
A lot of food and beverage products require high fill temperatures. Common food products would include: Soups, sauces, dressings, marinades, and other condiments. Some beverages include: Flavored waters, drink mixes and some vegetable juices.
What Types of Hot Fill Plastic Bottles are Available?
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 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 195 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 500 ml plastic bottle.
Why Choose Hot Fill Plastic Bottles over Glass Bottles?
We have seen several customers transition from glass bottles to one of the hot fill plastic bottles we offer. One of the primary reasons is that plastic bottles are light weight, which decreases shipping costs. Another reason customers are switching to plastic is to avoid breakage. Our customers are tired of glass bottles breaking during transportation especially customers that utilize e-commerce.
