What is ECO Friendly Packaging Material PVA

With people paying more and more attention to environmental protection, the "white pollution" brought to the environment by the use of plastics has attracted the attention of the world. therefore, materials with biodegradability have developed vigorously. Polyvinyl alcohol film has excellent microbial decomposition performance, can be decomposed into carbon dioxide and water, does not pollute the environment, but also has some unique properties, such as: gas barrier, transparency, antistatic, strength and toughness, solvent resistance, water solubility, etc., which can meet the various requirements of various industries for the film, so it has caused an upsurge of development and application.

The characteristics of PVA thin films as below.
1. Environmental friendliness: PVA film can completely dissolve and flow away with Rain Water, participate in the cycle of nature, will not form a headache "white pollution", can effectively prevent the spread of toxic and harmful substances.
2. Hygienic characteristics: many research institutions such as the United States and Japan have conducted experiments on polyvinyl alcohol in a related range, and the results have proved that polyvinyl alcohol is non-toxic.

3. Water soluble: soluble in water, insoluble in almost all organic solvents.
4. High permeability: the performance of PVA film to block oxygen and nitrogen better than other films.
5. Oil resistance: PVA film has excellent resistance to animal oil, vegetable oil, mineral oil and so on.

6. Acid resistance: PVA film has strong resistance to weak acid and weak alkali.

in addition, PVA film has good printability, excellent heat sealing performance and protection. Dust performance, transparency, glossiness and tension are equal to or better than traditional plastic films.
     PVA thin film has excellent barrier property, water solubility and environmental friendliness. It has been widely recognized by environmental protection authorities and users, and is more and more widely used in packaging, textile embroidery, water transfer printing and other fields. For example, pesticides, chemical fertilizers, dyes, detergents, water treatment agents, mineral additives, detergents, chemical reagents for garden care, etc., can also be used as rapeseed, plant seed bags, clothing bags, food and hospital washing bags and other products packaging.
