43.5g 28-400 SpH PET Preform

What this packaging is

A short, cylindrical body paired with a 28mm neck and 400 SpH finish makes this preform a reliable starting point for blow-molded bottles across household and personal care lines. The 43.5g 28-400 SpH PET Preform is engineered for compatibility with a wide range of standard closures and automated filling equipment, keeping multi-SKU integration straightforward. Consistent neck dimensions across production runs simplify line changeovers for dish soap, surface cleaners, household cleaners, and wash formats. Custom color options are available with an 8-week lead time for tailored runs. Made in the USA, it's a solid, low-complexity choice for domestic brands building out scalable cleaning product lines.

Why brands choose this

• 400 SpH neck finish for broad closure compatibility: The 28-400 SpH neck finish aligns with one of the most widely used closure standards in household and personal care, meaning brand teams can source caps from multiple vendors without retooling or custom fitment work.
• Consistent neck dimensions across multi-SKU lines: Uniform neck geometry from preform to preform keeps automated filling and capping lines running smoothly, reducing integration headaches when ranging across dish soap, surface cleaners, and wash formats under a single production setup.
• USA-made with custom color in 8 weeks: Domestic manufacturing cuts lead times and removes the customs complexity that offshore sourcing adds, and the 8-week color customization window gives brand teams a realistic path to differentiated shelf presence without long production cycles.
