Normal temperature water-soluble PVA film is a novel water-soluble fully degradable plastic. It is widely used in packaging, water transfer printing, liquid crystal display, high-end clothing embroidery and other fields. It is a film product with higher added value. However, prior to this, domestically produced PVA films have the disadvantages of slow film formation, poor peeling properties, poor uniformity, etc., and foreign countries have also imposed technical blockades on our country. At room temperature, water-soluble PVA films can only rely on imports for a long time.
Yongan Sanyuanfeng Water-soluble Membrane Co., Ltd., after years of research and development, has independently developed a complete set of formulations and production equipment, and accelerated the filming speed of domestically-made water-soluble PVA films from the previous 5 to 7 meters/minute to the current 11 meters/minute. In this way, the production efficiency is greatly increased, which can significantly reduce the production cost. At the same time, the company improved the transparency, peelability and uniformity of the product. The PVA film produced has the characteristics of high transparency, good gloss and oil and solvent resistance, heat sealable printing, excellent antistatic properties and anti-counterfeiting features, etc. Tensile strength, tension and other indicators have reached the advanced level in foreign countries, and the comprehensive performance is close to the advanced level in foreign countries. Tested by the Fujian Provincial Center for Inspection and Verification, the quality of this product has reached the Q/YSYF001-2006 corporate standard, and it can completely replace similar imported products, with significant economic and social benefits.
At present, the price of water-soluble PVA film at room temperature in the domestic market: US product is 130,000 to 170,000 yuan / ton, Japanese products is 200,000 to 250,000 yuan / ton, while domestic products are only 40% of US products, average selling price Only 60,000 yuan / ton, so the price of domestic products is very competitive. According to reports, China's project technology has been basically mature, and to achieve industrial production, Yongan Sanyuanfeng Water-soluble Film Co., Ltd. already has 4 high degree of automation of the production line, the monthly production capacity of up to 1.1 million square meters.
