Product Features

Designed for Large Water Bottles

This PET preform is developed specifically for 5-gallon water containers. The heavier body structure provides enough material distribution for large-volume blow molding.

Stable Performance on Automatic Blow Molding Lines

Weight consistency and neck precision directly affect production efficiency. Tight dimensional control helps reduce bottle defects, minimizes machine adjustments, and keeps production lines running smoothly.

Excellent Transparency

Food-grade PET resin produces a clean and transparent appearance after blowing.

Low Acetaldehyde Control

For drinking water packaging, odor control is often a concern. Our low-AA production technology keeps acetaldehyde content ≤2 ppm, helping preserve the natural taste of purified water and mineral water.

Reliable Bottle Neck Accuracy

The 55mm neck finish is manufactured with strict tolerance control, supporting cap compatibility and reducing leakage risks during filling, transportation, and storage.
