Engineered for
Large-Format Water Containers
Our 55mm neck finish PET preforms are purpose-built for high-capacity water packaging -- delivering the wall strength, sealing integrity, and reusability that large-volume buyers demand.
5-Gallon Water Bottle
Preform
The 55mm preform is the industry-standard choice for 5-gallon (18.9L) bottled water. Designed for commercial water dispensers and direct delivery, it must meet the highest standards for structural integrity, airtight sealing, and multi-use durability -- all of which our preforms deliver.
Optimized preform weight ensures sufficient wall thickness for large-volume bottles, preventing collapse under load.
Standard 55mm thread profile matches universal water dispenser caps, ensuring seamless fit across all major equipment.
High-grade PET resin formulation withstands repeated wash-and-refill cycles without yellowing, cracking, or odor retention.
Reinforced neck and body geometry resist stacking pressure and impact during long-haul logistics and warehouse storage.
Beyond the 5-gallon format, our 55mm preforms are also used across a range of large water container applications -- each with specific performance demands we're built to meet.
