Abstract
The invention discloses a biodegradable polyvinyl alcohol thin film. The biodegradable polyvinyl alcohol (PVA) thin film is prepared from, by weight, 60-80 parts of polyvinyl alcohol, 15-30 parts of starch, 0.1-0.5 part of a coupling agent, 0.2-0.5 part of an antioxidant and 0.3-1.5 parts of a solubilizing agent. A preparation method of the biodegradable polyvinyl alcohol thin film comprises the following steps of 1 raw material mixing, wherein polyvinyl alcohol, the starch, the coupling agent, the antioxidant and the solubilizing agent are mixed according to the weight proportion; 2 plasticizing, wherein plasticizing processing is performed with an internal mixer; 3 extruder granulating; 4 film blowing and shaping. The prepared biodegradable polyvinyl alcohol thin film is flexible, smooth, good in oil resistance, solvent resistance, abrasion resistance and gas permeability resistance, capable of achieving the water resistance through special treatment and wide in application.
