Nano-inorganic modified polyvinyl alcohol solution development technology was introduced in Gaoyang County, Hebei Province in October 2003, reaching world advanced level.
According to reports, nano-inorganic modified polyvinyl alcohol aqueous solution using composite coating process, the production of high barrier film has excellent transparency, gloss, fragrance, polarity and oil resistance, organic solvent resistance, and non-toxic No pollution, it is an environmentally friendly product. The production process of this kind of solution is simple, the comprehensive cost is low, and the application field is wide. It can be applied to various types of packaging such as clothing, leather, file archives, chemical raw materials, machinery, and food.
Tested by the laboratory of China Packaging Research and Testing Center, this new product has three times less oxygen transmission and less than one-time water vapor transmission compared with PVA before modification, which is far lower than that of similar foreign products. To reach the world advanced level, however, the cost is only 1/7 of EVOH. It is understood that only a few developed countries in the world can produce similar products and have high oxygen transmission and high cost. Regardless of performance or price, the nano-mineral modified polyethanol aqueous solution technology developed by Gaoyang County is highly competitive. Strength and broad development prospects.
