一只塑料袋的诞生记录

来源：/ 日期：2023-11-21

塑料袋在日常生活中似乎司空见惯，它常见得好像让大家都不是特别关注它是怎么生产的。

Plastic bags seem to be commonplace in daily life, as they seem so common that no one particularly pays attention to how they are produced.

这些小颗粒就是塑料袋的母体，学名PE，俗名塑料粒子。塑料袋的制作是离不开它的，它经过吹膜，印花，分切等多重工序才能得到一条能使用的成品塑料袋。

These small particles are the matrix of plastic bags, commonly known as PE or plastic particles. The production of plastic bags cannot be separated from it. It requires multiple processes such as film blowing, printing, and cutting to obtain a usable finished plastic bag.

这个工序就是神奇的吹膜过程。工人会将调配好的原料置入机器里，机器将颗粒进行加热，融化粒子。然后吹出如图所示的塑料薄膜，接着滚压机将塑料薄膜进行压平和宽度的裁剪。

This process is a magical film blowing process. The workers will put the prepared raw materials into the machine, which will heat the particles and melt them. Then blow out the plastic film as shown in the figure, and then use a rolling machine to flatten and cut the width of the plastic film.

这条工序是白袋的印刷过程。将吹好的大卷白袋放到印刷机器上，印刷机器就会根据客户的需求进行色彩的印刷。这里采用的滚筒印刷，一种颜色就得需要一个滚筒版子，所以印刷多色的话成本就会增加。

This process is the printing process of white bags. Place the blown large roll white bag on the printing machine, and the printing machine will print colors according to the customer's needs. The roller printing used here requires a roller plate for each color, so printing multiple colors will increase the cost.

一步就是分切啦。印刷好的大卷袋子通过分切机器进行裁剪，裁去多余的部分。然后经过打包阿姨的手工整理捆扎。就成了大家手中的成品塑料袋啦。

One step is cutting. The printed large roll bag is cut using a slitting machine to remove excess parts. Then, after being manually organized and tied by the packaging aunt. It has become a finished plastic bag in everyone's hands.

这张图上是旗源工厂做过的一些案例，基本上都是单面单色印刷的。因为相比较彩色印花而言，单面单色的成本更低。不过话又说回来，彩色印刷更能吸引眼球，广告效果会更好。

This picture shows some cases made by Qiyuan factory, which are basically printed on one side and in one color. Because compared to color printing, the cost of single sided monochrome is lower. But then again, color printing is more eye-catching and the advertising effect will be better.
