PET Preform for Water Bottle

Our solutions for the water market range from bottles and preforms for large-scale distribution to water coolers for home and office dispense.

When sourcing preforms for mineral water, you cannot afford risks that compromise your brand. Any trace of off-flavor undermines taste integrity, any haze or yellowing dulls shelf appeal, and any neck-finish mismatch triggers costly downtime.

Lightweight bottles must cut freight without sacrificing top-load and stacking strength. At the same time, your teams need globally recognized neck standards, complete compliance documentation, and secured capacity—for both on-the-go bottles and 5–18.9 L cooler formats—without disrupting current blowing or filling settings.

You’ve likely seen consumer reviews such as “this water tastes strange” or “there’s a metallic aftertaste,” even when the source water is fully compliant. In practice, root causes often sit in the packaging chain—for example, elevated acetaldehyde (AA) from resin drying/overheating, sub-standard closure liners leaching sulfur-based curatives or plasticizers, or residual processing volatiles that weren’t adequately aired out.

Our solution is to control AA at the source, specify food-contact-certified liners with migration reports, validate sealing torque and cap fit, and run sensory/AA checks against agreed targets—so the natural character of your mineral water stays exactly as consumers expect.

Bottled Water — PET Preforms & Bottles

At Enlightening Plast, you get PCO 1881/1810 water preforms engineered for low AA and high transparency, so your water tastes pure and looks pristine on shelf. We offer 100% virgin PET or up to 100% rPET (where regulations permit), with lightweighting that preserves top-load and stacking performance.

We validate cap fit and sealing torque to your closure spec, align preforms to your blowing window for fast start-up, and package for export with batch traceability + COA. The result is stable blowing, fewer stoppages, and a clean, efficient path to scale.

Bulk Water — 5–18.9 L Cooler Bottles & Preforms

For bulk formats, our 55 mm PET preforms cover 5–18.9 L and are available in returnable or one-way types. Returnable designs deliver long service life for offices—often supporting a full year of use with proper handling—while one-way options suit short-term offices, meetings, events, camping, job sites, and other mobile scenarios with no bottle deposit required.

We build thick-wall, leak-resistant geometry to protect the product in long transit, support rPET or virgin PET choices, and provide export-ready packaging so you maintain supply continuity across seasons and routes.
