Foresight’s PVC flexible fabric is used to make the biogas digester bag. The biogas digester bag has long life, good airtightness, and environmental protection characteristics, and it is widely used for fermentation for home waste, farms, sewage treatment, and storing various gases.
Foresight has over 15 years of experience in fabric production, with an annual output of more than 5 million square meters; there are many application cases and verifications of large and medium-sized biogas engineering customers and household customers at home and abroad, and we have assisted biogas engineering units in the construction of over 500,000 households. At the same time, we have advanced high-frequency orbital welding machines, C-type welding machines, professional fabric welding technology, finished product processing teams, clean and spacious dust-free workshops, unparalleled processing methods, processing speeds, and delivery capabilities, allowing us to provide one-stop services for the production of stable-quality biogas materials and the processing of finished products for domestic and foreign environmental protection.
