摘要
通过改进配方及试验工艺提高聚乙烯醇(PVA)水溶包装膜的产品质量,配方及工艺控制条件可控性能精准、良好,容易控制操作,包装膜的双向拉伸性、柔韧性、透明性等有了较大提升,经过测试PVA水溶包装膜的延伸率(%)>600、拉伸强度>400 MPa、透光率>91.0%。
The product quality of PVA water-soluble packaging film was improved by improving the formula and test technology. The controllable properties of the formulation and process control conditions were accurate,good,easy to control and operation,the biaxial stretch and flexibility of the packaging film were improved.The transparency has been greatly improved,the elongation of the PVA water-soluble packaging film is more than 600,the tensile strength is more than 400,and the transmittance is greater than 91.0.
