As global demand for food‑safe packaging polyester materials keeps rising, **Wankai New Materials** continues to deliver high‑performance bottle‑grade PET chips for beverage and edible‑oil packaging sectors, distributed by Jiangsu Zijun International Trade. Wankai’s bottle‑grade PET series complies with US FDA 21 CFR 177.1630 and EU 10/2011 food‑contact regulations, supporting mass production for bottlers across global markets
Water‑bottle PET grades are widely adopted for mineral water, purified drinking water and small‑size beverage containers. **WK‑801** remains the market‑leading water‑bottle PET grade, featuring intrinsic viscosity of 0.80±0.015 dL/g, acetaldehyde content ≤1.0 μg/g and melting point 247±2 °C. It delivers excellent transparency, low AA value and stable blow‑molding performance for standard water bottle production.
For edible‑oil packaging, **WK‑821** is Wankai’s dedicated oil‑bottle PET resin. With intrinsic viscosity 0.83±0.015 dL/g, WK‑821 brings enhanced mechanical strength and better barrier performance, critical for large‑volume edible‑oil bottles. The material maintains low acetaldehyde level, stable melt flow and high finished‑product yield during stretch blow molding. It fits 1L‑5L edible oil bottles, cooking‑oil containers and certain pharmaceutical bottle applications, meeting strict food‑safety requirements for long‑term oil storageWankai.
All Wankai bottle‑grade PET resins are produced under standardized quality control, with stable L‑value and b‑value color indexes to reduce batch‑to‑batch color deviation. As a reliable supplier, Jiangsu Zijun International Trade keeps spot inventory for WK‑801, and WK‑821, supporting flexible order volumes for converters, bottling factories and plastic distributors worldwide.
