38.5g 38-400 PET Preform

What this packaging is

A 38mm neck diameter and 38-400 threaded finish define this 38.5g PET preform, built for blow molding into bottles across juice, milk, water, and plant-based beverage applications. The cylindrical preform profile supports consistent, repeatable bottle forming and works with standard screw-on closures for efficient fill-line integration. Available in custom colors with an approximately 8-week production lead time, it's a practical, well-spec'd starting point for beverage brands building or scaling a bottling program. Made in the USA, it simplifies domestic supply chains and keeps production timelines predictable for brands working with regional co-packers or fillers.

Why brands choose this

• Domestic production keeps beverage supply chains tight: Made in the USA, this preform reduces lead time uncertainty and removes import complexity for brands working with domestic co-packers or regional fillers — a real operational advantage when production schedules are tight.
• 38-400 finish plays well with standard closures: The 38-400 threaded neck is one of the most widely used finishes in beverage packaging, meaning brands get broad compatibility with off-the-shelf caps and filling equipment without costly tooling changes.
• Custom color availability opens up brand differentiation: Beyond standard clear, this preform is available in custom colors — giving beverage brands a straightforward way to create a distinct bottle aesthetic at the preform stage rather than relying entirely on label work.
