Transparent PET Preform 20 Liter

This transparent PET preform 20 liter is made from 100% food-grade virgin PET resin in our China factory. As a reliable supplier, we handle bulk wholesale orders for drinking water plants and beverage makers. It fits standard 55mm caps and runs smoothly on regular blow molding machines.

Food-Grade Safe Raw Material

100% virgin food-grade PET resin is used with zero recycled content. All preforms are FDA and SGS certified, fully complying with US and EU food contact regulations for drinking water and beverages.

Standard 55mm Reinforced Neck

The neck is built to the PCO 1881 global threading standard, ensuring compatibility with most filling lines and caps on the market. A 5.0mm reinforced structure delivers strong pressure resistance, effectively preventing cap loosening or leaks after filling and reducing post-filling defect rates by over 90%.

Precise Wall Thickness Control

Precision injection molding maintains wall thickness tolerance within ±0.2mm, eliminating weak spots that may cause bottle bursts during blowing. Compared with uneven preforms, PET material waste drops by around 3% per 10,000 units.

Flexible Weight Options

Multiple preform weights are available to suit different bottle designs. The 650g specification is suited for room-temperature water, while the 780g version is designed for carbonated drinks or long-distance shipping.

Custom Branding Support

We support custom colors, sizes, and logo printing. This helps build your brand's visual identity and makes your 20L bottles stand out in the market.

This transparent PET preform is designed for producing 20 liter water bottles used in drinking water packaging. It works together with bottle caps, handles, and water bottle racks to support a complete production and distribution process.

Q: What if the received preforms have problems during blow molding? 

A: If blow molding fails due to preform quality issues (such as uneven wall thickness or crystallization defects), our PET bottle preform supplier provides free replacement service.

Please conduct blow molding tests within 7 days of receiving the goods and provide detailed test reports (including blow molding parameters and failure photos).
