The Key Advantages of our 5 Gallon PET Preform
Low Acetaldehyde
Made from food-grade PET resin, our 55mm Water Cooler PET Preform features strictly controlled processing temperatures to keep acetaldehyde content below 0.02 mg/L. This helps prevent taste impact and meets China's BB/T 0060-2025 standard for food contact safety.
Stable Gram Weight
Consistent gram weight helps shorten blow molding adjustment time and maintains stable bottle wall thickness during large-scale PET bottle production.
High Impact Strength for Long-Distance Transport
Our 55mm Gallon PET Preform features a thicker wall design, helping finished bottles resist deformation during stacking and transport. From the factory and filling line to final sales, the bottle body remains stable and durable.
