49g 28-400 SpH PET Preform

What this packaging is

A 28-400 SpH threaded neck finish and 49-gram weight make this cylindrical PET preform a reliable foundation for blow-molded bottles in the cleaning and wash category. The 49g 28-400 SpH PET Preform is built for compatibility with industry-standard caps and closures, with consistent neck dimensions that support efficient capping line integration. Custom color options are available with an eight-week lead time. Manufactured and warehoused in the USA, this preform simplifies supply chain logistics for brands producing household cleaners, dish soaps, surface cleaners, and wash products at scale.

Why brands choose this

• USA manufacture streamlines supply for cleaning brands: Made and warehoused domestically, this preform cuts customs complexity and supports tighter production schedules for brands running high-volume cleaning and wash SKUs.
• 28-400 SpH neck ensures broad closure compatibility: The standardized 400 SpH threaded finish integrates cleanly with a wide range of caps, reducing tooling risk and simplifying closure sourcing across multiple product lines.
• Custom color options support brand differentiation at the shelf: With color available on request, brand teams can build visual distinction into the bottle itself rather than relying solely on label design, a real advantage in a crowded household cleaning aisle.
