PET YISHENG YS-W01

Crafted for Clarity, Built for Safety: The Ultimate Material for Your Bottled Water PET YS-W01 is a high-performance, food-grade polyester chip engineered specifically for the production of bottled water containers. With ultra-low acetaldehyde content (≤1.0 µg/g) and minimal moisture (≤0.2 wt%), it ensures odor-free, chemically inert packaging that preserves the taste and purity of water—even under heat or extended storage. Its optimized diethylene glycol (DEG) content provides the ideal balance of flexibility and strength for lightweight, durable bottles. Manufactured to meet stringent global food-contact standards, PET YS-W01 delivers brilliant clarity (L ≥82, b ≤0), low dust levels, and consistent processability on high-speed blow molding lines. Ideal for single-use and reusable water bottles, sports drinks, and sensitive applications like infant formula packaging.
