塑料包装行业是随着机电技术的进步和塑料加工工艺的发展而发展起来的,并逐步形成为一个独立的工业部门。上世纪六七十年代后,许多塑料原料已能大规模生产,塑料制品代替金属、木材、玻璃、纸、纤维等材料制成的产品,在国民经济各部门和人们生活各个领域的应用越来越多。需求的不断增加使得中国塑料包装机械发展很快、生产出来的品种也越来越多,大多已能供应国内塑料制品加工装备的需要,随着技术的不断更新,近年来以伺服系统为主要执行元 Plastic packaging industry is with the progress of mechanical and electrical technology and the development of plastic processing technology developed and gradually formed into an independent industrial sector. Since the 1960s and 1970s, many plastic raw materials have been able to be mass-produced. Products made from plastic, metal, wood, glass, paper, fiber and other materials have been used more and more in various fields of the national economy and in various fields of human life more. Increasing demand for plastic packaging machinery in China has developed rapidly, more and more varieties produced, most of them have been able to supply domestic plastic processing equipment needs, with the continuous updating of technology in recent years, the main implementation of the servo system yuan
