6 Reasons You Trust Our PET bottle Preforms

 

Low AA Control

Excess acetaldehyde (AA) directly affects the taste of drinking water. Our PET bottle preforms maintain AA levels ≤3ppm, higher than the industry standard, helping you ensure water purity from the source.

Lightweight Design

While maintaining blow molding strength and rigidity, we can produce PET preforms at some of the lowest weights in the PET preforms market for the same specifications.

High Clarity

Our PET preforms use 100% virgin PET resin, resulting in high transparency and no impurities. After blow molding, the bottles are clear, ideal for water brands with high appearance standards.

Weight Consistency

We control PET preforms' weight tolerance within ±0.3g, ensuring stable operation on your high-speed blow molding lines and effectively reducing scrap rates and downtime risk.

Equipment Compatibility

Our preforms are dimensionally verified and compatible with major blow molding machines such as Sidel, Krones, and SIPA, allowing direct production without line adjustments or mold changes

Food Grade Compliance

All water PET preforms meet FDA, EU 10/2011, GB 4806.7, and other international food contact standards, helping you comply with import requirements and regulatory standards across different target markets.

How Do We Ensure PET Preform Meets Your Quality Standards?

Raw Material Inspection

Each batch of PET resin is tested upon arrival at the factory for intrinsic viscosity (IV, ≥0.76 dl/g for bottle-grade PET), AA (acetaldehyde) content, moisture, and color value. Any material that fails is strictly excluded from the production line.

In-Process Quality Control

During production, we conduct batch inspections of PET preform weight, wall thickness, and neck dimensions, maintaining a weight tolerance within ±0.3g to ensure consistent performance on your blow molding lines.

Pre-Shipment Testing

Before shipment, we perform PET preform quality testing, including blow molding yield tests and full appearance inspection. AA levels must meet water-use standards, and food-contact products are accompanied by third-party test reports, ensuring each batch complies with target market requirements.

Shipment & Documentation

We provide complete shipping documents for your PET preforms, including COA certificates, ISO 22000 / ISO 9001 certification files, and third-party food contact test reports, facilitating customs clearance, inspection, and internal audits.
