Food grade high clarity PET water preform for bottled drinking water. Low acetaldehyde, precise thread, support custom preform design & mold development.
Flexible customization to meet your brand requirements
While the neck dimensions (28mm / 30mm / 38mm) are strictly standardized to match global capping systems, the body diameter, overall length, and wall thickness distribution are fully customizable. This allows us to optimize the stretch ratio for your specific bottle shape and blow-molding equipment.

Every packaging project has unique constraints. Whether you are choosing a standard preform from our 28/30/38mm matrix or need a bespoke solution, our engineering team is equipped to deliver.
Color Customization We offer full masterbatch and liquid color dosing integrated into the injection molding process. From transparent blue and green to solid amber and custom Pantone matching, we maintain food-contact compliance across all neck sizes.
Size Customization If your target bottle requires a specific gram weight that falls between our standard models (e.g., a 31g preform for a 500ml bottle), or if you need a custom neck finish adaptation, we can adjust the mold design or injection parameters to hit your exact specifications.
Mold Customization We design and manufacture preform injection molds from single-cavity prototypes to high-cavity production tools (8, 16, 24, 32, 48+). Our mold flow analysis validates gate location, cooling layout, and shrinkage compensation before steel is cut. We also offer mold modifications for existing tooling to help you transition to a new preform weight with minimal capital investment.
