Description:
PVA water-soluble plastic film is a kind of processing by the special craft processing, rapid degradation by natural factors (H2O), so it belongs to is a new kind of environmental protection packaging materials. In Europe, America, Japan and other countries are recognised by environment department. Due to its environmental characteristics, therefore has wide attention by the developed countries in the world. Pesticides, chemical and other industries abroad large companies have been widely used water-soluble film packaging their products. Along with society's development and progress, people more and more attention to the protection and preservation of our environment, especially after China's entry into the WTO, with the developed countries in the world, for environmental requirements of the packaging is increasing day by day, thus water soluble packaging film in China must have a wide prospect in application.
Product Feature :
(1) have the characteristics of water-soluble, soluble in cold water. Water soluble speed can be design choices, non-toxic pollution-free.
(2) the antistatic property of water-soluble film is a film, anti-static, unlike other plastic film, has good antistatic property in the process of using water soluble film packaging products, not cause its plasticity reduces as the electrostatic and electrostatic dust attached to the performance.
(3) moisture and gas transmittance. Water soluble film of water and ammonia has strong permeability, but the oxygen, nitrogen, hydrogen, carbon dioxide gas with good barrier property, etc. These characteristics, make its can be in good condition to keep the ingredients and the original smell of packaged products.
(4) heat sealing water soluble packaging film has good heat sealing, suitable for resistance high frequency heat sealing, heat sealing and heat sealing strength is related to such conditions as the temperature and humidity, pressure, time, generally greater than 200 g/cm2.
(5) mechanics performance. The mechanical properties of water soluble packaging film: strong sexual modulus of 2500 ~ 400 kg/cm2, tensile strength of 400 ~ 200 kg/cm2, tearing force 200 ~ 50 kg/cm2, elongation of 150 ~ 220%.
(6) oil resistance and chemical resistance of water soluble packaging film has good oil resistance, vegetable oil, animal oil, mineral oil), fat and organic solvent resistance and carbohydrate, etc.
Product Application:
(1) pesticides, chemical products lining inner packing bags. Can avoid touching pesticides and chemical products, no pesticide residues in the plastic bags;
(2) the cement additives (silicon powder, etc.) bag. Avoid dust is bad for the environment;
(3) the embroidery, the wig fabric such as carrier. Against the carrier, easy to clean;
(4) large artificial stone mold release membrane. Within the type membrane mat water soluble film, can quick demoulding;
(5) surface printing (water transfer printing). After printing on the film can be transfer to the surface;
(6) seeds. The seeds according to the fixed interval packaged buried again, save precious seeds, will save the busy for thinning;
(7) hospital washing bags. No contact with contaminated clothing can also be clean;
(8) hot water soluble film used clothing packaging;
(9) and other plastic composite can be used for packaging for food and air cushion bag.
