据“Plastics Industry News,1993;39(6):84”报道,日本三菱塑料公司已生产出2种新品种的聚酯薄膜——吸水薄膜及水溶薄膜.吸水薄膜的吸水量可达自身质量的30倍,70μm厚的该膜每平方米可吸水2.5kg.除吸水外,这种薄膜还可吸收血液及尿液,并在一定时间后排出溶胶.水溶薄膜在水中的溶解速度是聚乙烯醇的5倍,在20℃以下它们的溶解特性是一样的.这两种聚酯薄膜广泛应用于医疗、药品包装及印刷行业中.
According to “Plastics Industry News, 1993;39(6):84”, Mitsubishi Plastics Corporation of Japan has produced two new varieties of polyester films - water-absorbing films and water-soluble films. 30 times the mass, 70μm thickness of the membrane can absorb 2.5kg per square meter. In addition to water absorption, this film can also absorb blood and urine, and after a certain period of time out of the sol. Soluble film in water dissolution rate is poly Five times of vinyl alcohol, their solubility characteristics are the same below 20°C. These two types of polyester films are widely used in medical, pharmaceutical packaging and printing industries.
