5 gallon PET preforms are typically used to produce PET water bottles of this size. These large water bottles are commonly used in commercial settings such as offices, schools, and hospitals, as well as homes with high water usage.

In addition to water bottles, this PET preform can also be used to produce other large containers such as jugs and other liquid containers, including juices, oils, and cleaning products. The strength and durability of PET make it a popular material for such containers, as it can withstand heavy use and resist impacts and other forms of damage.

PET preforms are also used to make smaller containers, such as bottles and jars, for a variety of different products, including food, beverage, and personal care. 5-gallon PET preforms are suitable for a wide range of applications in the packaging industry, especially for products requiring large durable containers.
