Core advantages focus on food-grade safety, precise dimensions, and stable performance, solving the pain points of poor compatibility and quality fluctuation in traditional preforms. All products pass multiple inspections to meet international standards, ensuring reliable application in global markets.

Food-Grade Safety & International Certification

All PET preforms are made of 100% food-grade PET resin (no recycled materials added), complying with FDA 21 CFR Part 177.1310 and EU 10/2011 food contact material standards. They have passed ISO 13106:2014 and GB/T 41102-2021 certifications,with no heavy metals or harmful substances,ensuring the safety of terminal packaging products. Each batch of products is accompanied by a quality inspection report for customs clearance and market access.

Precision Injection Molding & Stable Performance

Adopting P20 steel molds (recommended by GB/T 41102-2021) and high-speed injection molding machines,our preforms achieve precise dimension control: cavity diameter tolerance ±0.01mm,length tolerance ±0.02mm,and surface roughness Ra≤0.04μm. The uniform wall thickness ensures consistent blow molding quality,with a product qualification rate of over 99%. The preforms have excellent thermal stability,supporting high-temperature blow molding (280-300℃) without deformation.

Strong Compatibility with Blow Molding Machines

Our PET preforms are designed to be compatible with most automatic blow molding machines (including Hench、Sidel、Krones models).
