57.7g 28-KERR PET Preform

What this packaging is

With a 28mm Kerr neck finish and a 57.7g body engineered for consistent blow-molding, this PET preform delivers uniform wall thickness and dimensional precision across high-volume runs. The 57.7g 28-KERR PET Preform is built for beverage and spirits applications — mixers, syrups, liquor, and ready-to-drink single-serving formats — where filling line reliability and closure compatibility are non-negotiable. Its smooth exterior integrates cleanly with automated capping equipment. Made in the USA, it shortens domestic supply chains and reduces import lead times for brands running high-velocity production. Color customization is available within an eight-week lead time.

Why brands choose this

• USA manufacturing keeps high-volume production on schedule: Made domestically, this preform eliminates the lead time uncertainty of imported materials — a real advantage for beverage and spirits brands running continuous filling operations where supply disruptions translate directly to lost production volume.
• 28mm Kerr finish means closure compatibility is a given: The standardized Kerr neck finish integrates with widely available closures and automated capping lines, reducing tooling risk and simplifying the transition from preform to finished bottle across mixers, syrups, liquor, and RTD formats.
• Engineered precision supports category-critical fill consistency: At 57.7g, this preform is designed for uniform wall thickness through blow-molding — important for single-serving and spirits packaging where fill accuracy, label registration, and shelf presentation all depend on dimensional repeatability at scale.
