專利摘要(英)
The present invention provides a polyvinyl alcohol film, which is a polyvinyl alcohol film modified by heat treatment. The thermogravimetric analysis curve after soaking in water for 2 minutes has a cracking signal of a plasticizer; before the polyvinyl alcohol film was not modified by heat treatment, the thermogravimetric analysis curve after soaking in water for 2 minutes did not have the cracking signal of the plasticizer. The polyvinyl alcohol film modified by heat treatment of the present invention can increase the water resistance of the polyvinyl alcohol film, so that plasticizer can be better preserved in the polyvinyl alcohol film when it encounters water molecules.
