, Water soluble film is low by alcoholysis degree of pva, using polyvinyl alcohol film, water soluble and degradability, made by adding various additives. Water soluble film as a new packaging material, conform to the requirements of environmental protection, more and more brought to the attention of the countries, is the domestic grew rapidly and is widely applied in various industries. So in addition to environmental protection this one characteristic, water soluble film what advantage? < br /> the advantage of water soluble film is as follows: < br /> 1, safe and convenient to use, avoid direct contact with the user by packaging, can be used for packages of harmful substances. < br />
2, mechanical performance is good, and can be heat sealing and heat sealing strength is higher.
3, degradation, completely water soluble film of polyvinyl alcohol with water and biological degradation characteristics, it dissolves in water to form adhesive solution infiltration in the soil, increase soil mass of viscosity, permeability and water retention, completely solve the traditional packaging waste handling problems. < br />
4, water soluble film also has the function of anti-counterfeiting, anti-counterfeiting of the best weapons can be used as quality products, extend the life cycle of products.
, Believe that as technology will greatly improve the performance of water soluble film, also will be more and more widely application field. < br />
