28mm PET Preform For Mineral Water Bottles

This 28mm PET preform for mineral water bottles​ is engineered for clarity and purity. Ranging from 330ml to 2 liters, these preforms are manufactured from 100% virgin food-grade PET. With low acetaldehyde content and uniform wall thickness, they ensure stable blowing performance and keep the original taste of drinking water intact during storage and transport.

Controlled Acetaldehyde (AA) Levels

We strictly control the AA value to ≤2.0 ppm. This minimizes the risk of odor development during water storage, ensuring the natural taste of mineral and purified water remains fresh.

High Clarity Finish

The preforms offer excellent transparency, allowing consumers to see the water quality clearly. Production is monitored to eliminate black spots, color deviation, and surface scratches, enhancing shelf appeal for bottled water brands.

Wide Weight Range for Cost Efficiency

With a versatile weight range of 8g to 45g, these preforms fit bottles from single-serve retail sizes to 2L family packs. Clients can select the optimal weight based on bottle height, wall structure, and transport distance to balance strength and material cost.

Precision Neck Finish

Every preform undergoes inspection for thread accuracy, sealing surfaces, and support rings. The precise 28mm neck finish ensures a perfect fit with caps, preventing leaks, loose caps, and inconsistent torque during capping and logistics.

Consistent Stretch Performance

Uniform material distribution guarantees consistent heating and stretching. This results in well-formed bottle shoulders and bases, reducing defects like thin walls or post-filling deformation.
