农用塑料薄膜容易破损,浪费惊人。国外农业技术先进国家,大多采用压敏胶带修补破损薄膜,以减少损失。这种胶带仅借助于手的压力,就能粘贴薄膜,修复破损。华东化工学院环境工程系于1988年接受上海市科委下达的研制任务。在配方上,考虑了聚乙烯农膜难粘,且表面污浊及处于户外冷、热、水、紫外光等老化因素作用的特点,采用新型的耐老化聚丙烯
Agricultural plastic film easy to damage, amazing waste. Foreign advanced agricultural technology countries, most of the use of pressure-sensitive adhesive tape repair damaged film to reduce losses. This tape can only be attached to the film by the pressure of the hand to repair the damage. East China Institute of Chemical Engineering Department of Environmental Engineering in 1988 to accept the Shanghai Science and Technology Commission issued the task of development. In the formula, taking into account the polyethylene film is difficult to stick, and the surface is dirty and in the outdoor cold, heat, water and ultraviolet light and other aging factors, the characteristics of a new type of anti-aging polypropylene
