Bioyer company owns a research team composed of over 10 experts in microbiology and doctors in microorganism engineer. After six years intensive study and repetitive experiments, they have successfully developed a kind of positive ion mildew proof paper . They skillfully put the active ingredient (BioArmor) with long carbon chain structure and positive charge on the packing paper by adopting the method of chemical link. As all the mould fungus takes negative charges and when the mould fungus with negative charges meets the BioArmor with positive charges, it will be attracted. And the surface of the special long carbon chain structure is like a sharp knife and can pierce into the cytoderm of mould fungus and destroy the food chain, on which the mildew lives. In that way, the mould fungus can’t propagate and grow. It is exactly the mould fungus ’s nemesis.
