45g 28-400 PET Preform

What this packaging is

A 28-400 neck finish on a 45-gram PET preform gives bottlers a reliable, high-throughput starting point for blow-molded container production. The 45g 28-400 PET Preform is manufactured in China with consistent shot weights and tight dimensional tolerances — critical when your downstream blowing line has zero tolerance for variation. At 5.39 inches tall and 1.08 inches in diameter, this preform is built for durability without unnecessary material weight. Custom color runs are available with a four-week lead time, and PCR content can be incorporated for brands tracking material reduction commitments. A practical workhorse for beverage, household, and industrial bottling programs.

Why brands choose this

• Custom color with PCR options built in: Available in custom colors with a four-week lead time, and PCR content can be incorporated — giving brand teams a straightforward path to color-matched, lower-virgin-resin packaging without a complex supply chain workaround.
• 28-400 finish matches the industry's most common closure ecosystem: The 28mm 400-finish neck is one of the most widely standardized specs in blow-molded bottling, meaning you get broad closure compatibility out of the gate and fewer tooling surprises when sampling or scaling.
• Tight dimensional tolerances that protect your blowing line: At a consistent 45g shot weight, this preform is engineered for predictable performance on reheat stretch blow-molding equipment — reducing rejects, downtime, and the kind of variability that quietly kills production efficiency.
