Resilux 29.8g 45-400 HF PET Preform

What this packaging is

A wide-mouth 45mm neck and 400 HF finish make this preform purpose-built for hot fill beverage lines. The 29.8g 45-400 HF PET Preform features a cylindrical single-piece construction with a smooth neck-to-body transition that integrates cleanly into standard filling equipment. The subtle blue tint distinguishes it on the line without affecting downstream label or sleeve decoration. Compatible with a range of cap styles, it supports flexible closure configurations for juice, plant-based milk, and other thermally processed beverages. Made in the USA, it's a reliable domestic-supply option for brands running high-volume hot fill production.

Why brands choose this

• Hot fill integrity where it counts: The 45-400 HF neck finish is engineered specifically for thermal processing, maintaining structural integrity and seal reliability through the heat cycles that juice and plant-based beverage production demands — reducing risk of deformation or closure failure at the line.
• Wide-mouth format accelerates fill speed: The 45mm neck opening supports rapid filling rates and easy integration into existing hot fill equipment, which matters when you're running high-volume SKUs like refrigerated juice or non-dairy milk and every second of line time has a cost.
• Domestic supply for leaner production planning: Made in the USA, this preform supports shorter replenishment cycles and reduces the customs and transit complexity that comes with offshore sourcing — a real operational advantage for brands managing tight production windows or fluctuating demand.
