HDPE Geomembrane Textured Impermeable Pond Liner
Our company adopts the latest domestic round die process production equipment, along with the use of high-quality polyethylene resin and self-developed formulas. We have reached agreements with Cabot, Saudi Basic Industries cooperation, ExxonMobil, Sinopec, etc., and established good partnerships to ensure timely supply of raw materials.
In order to ensure 100% product pass rate, quality control department of the company to implement the production line inspection and random inspection of finished products, for the quality of the “Zhonglong” brand to provide double insurance.
