55mm PET bottle preforms heat up quickly and stretch evenly during blow molding, making them a good fit for high-speed automatic bottle production lines. Their stable structure helps reduce mold wear, machine downtime, and production waste. Precise neck and body dimensions allow smooth matching with different caps and automatic preform feeding systems. The material also performs well in low-temperature conditions, supporting cold-chain transport and short-term refrigerated storage without easy deformation or leakage before delivery. As a China manufacturer and factory supplier, Enlightening Pallet provide wholesale 55mm PET bottle preforms with consistent quality, stable production capacity, and customized solutions for beverage, water, and food packaging applications.

The Key Advantages of 55mm PET Bottle Preforms

When preform dimensions shift around, the bottle blowing process gets problematic. Rejection rates go up. So, we stick to high-precision molds. Each batch stays fairly consistent, which makes these preforms work well on automated blow molding equipment.

High Transparency

Made from food-grade PET resin with controlled drying and injection molding, 55mm PET Bottle Preforms have clear walls with low haze and less whitening. After blow molding, the finished bottle looks clean, bright, and suitable for bottled water and beverage packaging.

Low Acetaldehyde Content

Regarding the material, bottled water safety is not something you can ignore. We manufacture preforms using food-grade PET. Acetaldehyde content ≤2 ppm, so food contact requirements for drinking water bottles are met.

Uniform Wall Thickness

Each batch of 55 mm PET preforms undergoes multi-point wall thickness measurement, with the wall thickness error controlled within ±0.10 mm.

Precise Cap Fit

The 55mm neck dimensions are tightly controlled to match standard caps, helping improve sealing performance and reduce leakage after filling.

Food-Grade PET Resin

Made from bottle-grade food-contact PET resin. No recycled material is used, helping keep color and clarity stable from batch to batch.

Application Industry

55mm PET preforms are primarily used for packaging bottled drinking water. Water filling plants heat and blow the preforms into 3-gallon or 5-gallon water bottles. The bottles are then filled, capped, labeled, palletized, and shipped.

Suitable Customer Types：
