一、前言迄今为止,国内绝大多数塑料制品加工厂生产食品或日用品印刷包装袋均分别在三台机器上先生产吹塑薄膜并收卷好,然后印刷、烫边、切割、制袋。而我厂在有关科研单位和工厂的协助下于一九八一年、测绘了一台从日本引进的样机。并自行试制了一台SJZ—M(YD)—45D_1—0.50吹塑薄膜印刷制袋机组。主要用于吹制高分子量、高密度聚乙稀薄膜,实现吹塑、印刷、制袋生产流水线。该机组根 I. Preface So far, the vast majority of domestic plastic products processing plants produce food or daily necessities printing and packaging bags are on the three machines were first produced blown film and rewind, and then printing, burning, cutting, bagging. With the help of relevant scientific research units and factories, our factory mapped out a prototype imported from Japan in 1981. And self-trial production of a SJZ-M (YD) -45D_1-0.50 blown film printing bag making unit. Mainly used for blowing high molecular weight, high density polyethylene film, to achieve blow molding, printing, bag production lines. The unit root
