Skip to content Enlightening Plast offers 28mm PET preforms built for reliable mineral water and beverage packaging. You can choose 100% virgin PET or 25%–100% rPET, delivering clear, stable, and food-safe material performance for daily bottling needs. Both standard-neck and short-neck options are available, along with a full 10g–55g weight range to match different bottle types and blowing conditions.
Each preform is molded with tight tolerances of ±0.2–0.5%, helping you keep bottle quality consistent from molding to filling. All materials meet FDA, EU 10/2011, and EN 1186 requirements, giving you confidence for global beverage applications. If you’re looking for stable supply, predictable performance, and a smooth fit with your bottling line, these 28mm preforms will support your production with fewer adjustments and more reliability.
Our 28mm PCO molds maintains thread geometry and sealing-surface flatness within ±0.05 mm, ensuring clean engagement with 1810, 1881, and BPF closures. This precision stabilizes torque performance across your filling line and maintains secure sealing for both still water and CO₂-retaining beverages.
By controlling eccentricity to ≤0.08 mm, each our 28mm PCO neck PET preform delivers uniform stretching when blown into 28mm water and beverage bottles. The resulting bottle has a straighter body, more stable vertical loading, and better consistency for high-speed palletizing and downstream automation.
Our low-temperature–resistant PET formulation and controlled cooling process keep the 28mm preform ductile between –5°C and 4°C. This stability prevents cracking during blow molding and ensures reliable bottle performance in chilled water, sports drink, and low-temperature CSD applications.
Every 28mm PET preform is monitored through automated weight inspection, holding each batch within ±0.1–0.2 g. This gives your blowing team stable bottle capacity and symmetric molding behavior, while supporting lightweighting programs that reduce resin consumption at high production volumes.
We use high-precision gate-cutting blades and a post-molding vacuum-debris removal process to ensure each 28mm preform has a smooth, clean gate profile. This keeps burrs under 0.02 mm and maintains a length tolerance within ±0.5 mm, helping you achieve reliable feeding and reduce unplanned stops in your automated lines.
A balanced cooling system and premium PET resin keep haze at ≤1.5% and limit mouth crystallization to below 3%. Our 28mm preforms consistently produce bottles with clean transparency and uniform gloss, a key feature frequently praised by the industry. They meet the high visual standards required by premium water and beverage brands.
We provide strong pre-sales support with 100% free samples, globally recognized certifications (FDA, EU 10/2011), and flexible customization on neck sizes, weights, and colors. Every detail is aligned with your project requirements before mass production.
Our after-sales service guarantees smooth cooperation through fast delivery within 7–15 days, 24/7 support, and a 3-year quality warranty on all preforms. We ensure your supply chain stays reliable and uninterrupted worldwide.
