33.55g 28-400 PET Preform

What this packaging is

A 28-400 neck finish and ratchet-style thread make this 33.55g PET preform a reliable starting point for blow-molded bottles across household and cleaning categories. The 28mm neck diameter ensures broad compatibility with standard screw closures, and the tapered cylindrical body delivers consistent wall distribution through the molding process. Weighing in at 33.55 grams, this preform suits surface cleaners, dish soaps, household cleaners, and wash products where structural integrity and leak resistance matter. Custom color options are available subject to lead times. Made in the USA, it fits neatly into domestic liquid packaging production workflows where supply chain predictability counts.

Why brands choose this

• USA manufacturing keeps domestic supply chains tight: Produced in the USA, this preform simplifies logistics for domestic blow molders and brand teams, reducing lead times and removing the customs complexity that comes with imported preform supply.
• Ratchet-style neck finish supports leak-resistant closure performance: The 28-400 ratchet thread is engineered for secure closure attachment, a non-negotiable for liquid cleaning products where leaks damage brand reputation and create retail liability.
• 28-400 compatibility spans the core household cleaning format range: The 28mm neck finish is one of the most widely used standards in surface cleaner, dish soap, and household wash packaging, giving brand teams flexibility across multiple SKUs without switching preform suppliers.
