by:POLYVA     2021-02-03
Product features: < br /> ( 1) Have the characteristics of water-soluble, soluble in cold water. Water soluble speed can be design choices, non-toxic pollution-free.
( 2) 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) Water 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 heat sealing and high-frequency heat sealing, heat sealing strength is related to such conditions as the temperature and humidity, pressure, time, generally greater than 200 g/cm2 < br /> ( 5) Mechanical properties. 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%.
( 7) 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 carbohydrates, but strong alkali, strong acid, chlorine free radicals and other can react with PVA, borax, boric acid, some dyes, etc. , this kind of material with water soluble film packaging is not recommended. < br /> this article key words: water soluble PVA film membrane water soluble PVA water soluble film water transfer printing film factory water soluble film < br />
