Products Advantages
1. Virgin PET Resin
Made from 100% virgin PET resin through injection molding, no recycled materials added. Blown bottles resist impact with strong load-bearing capacity. FDA food-grade certified for safe use by water bottle manufacturers.
2. Low Acetaldehyde Content
PET resin undergoes solid-state polymerization, minimizing acetaldehyde (AA) residue. Ensures filled drinking water maintains original taste without off-flavors.
3. High Clarity
Water bottle preform molded with precision injection molds, creating smooth, flawless surfaces. Blown bottles achieve high transparency, showcasing clear water quality and building consumer confidence.
4. ≥98% Blow Molding Success Rate
PET bottle preform features uniform wall thickness distribution without thin-thick variations. Even heating during blow molding ensures consistent stretching, achieving 98%+ success rates while reducing waste and material loss.
5. Pressure and Drop Resistant
Preforms weigh 650-750g with robust construction. Blown bottles withstand full 5-gallon water weight. Reinforced bottom prevents bulging or cracking during handling.
6. Excellent Neck Sealing
Precision-machined neck with smooth, burr-free finish. Compatible with tamper-evident caps, clear threading ensures tight sealing without leakage risks.
