Plastic bags are commonly used in people's daily life. Shopping on the street, shopping for vegetables, clothing packaging and loading garbage... Plastic bags are very useful, but have you ever thought about how plastic bags are made when you use them? What about plastic bag printing? Shunxin plastic packaging will introduce you. At the same time, I hope you will cherish the environment and choose plastic bags as much as possible.

1:塑料袋制作之塑料薄膜的形成

1: Formation of plastic film made of plastic bag

众所周知，塑料袋是塑料薄膜制成的，那么塑料薄膜又是怎样形成的呢?这是塑料袋制作步:吹塑。吹塑是将采购的原料塑料颗粒通过吹塑机吹制成塑料薄膜

As we all know, plastic bags are made of plastic film, so how is the plastic film formed? This is the plastic bag making step: blow molding. Blow molding is to blow the purchased raw material plastic particles into a plastic film through a blow molding machine

2:塑料袋印刷的流程

2: Plastic bag printing process

塑料袋印刷的前提是塑料薄膜和版子的位。前一步讲了吹塑，形成订单规格的薄膜后，要着手印刷了。根据所需印刷图案先要制版，一般制版和吹塑是同步的，也是吹塑完成后，版子也应该制好了，通常制版需要4天时间左右。

The premise of plastic bag printing is the position of plastic film and plate. In the previous step, we talked about blow molding. After forming the film of order specification, we should start printing. Plate making is required first according to the required printing patterns. Generally, plate making and blow molding are synchronized. After blow molding, the plate should also be made. Usually, plate making takes about 4 days.

塑料袋印刷分单面或双面以及颜色区分。比如购物袋，一般以单面或双面一两个颜色为常见，一个颜色对应版，但并非双面颜色相同可以共版，这是不行的，譬如双面各两个颜色得制作4块版。塑料袋印刷一般为凹印，采用多为铜板，也有胶版。

Plastic bag printing is divided into single or double sides and color differentiation. For example, shopping bags are generally made of one or two colors on one side or both sides. One color corresponds to the version, but not the same color on both sides. You can share the version. This is not possible. For example, four versions have to be made for two colors on both sides. Plastic bag printing is generally gravure printing, mostly copper plate and offset plate.

印刷机组安好版子和卷料，调好油墨，可以印刷了

The printing unit installs the plate and roll, adjusts the ink, and can print

3:根据不同的塑料袋种类，印刷好的塑料薄膜制袋方式不一样。有需要边的、需要复合的、需要切割的、需要打孔的、需要焊提手的。。。

3: According to different types of plastic bags, printed plastic films are made in different ways. There are those that need edge, compound, cutting, punching, welding handle...

但是到了这一步，已经是塑料袋制作的后环节了，基本上可以成型了

However, at this stage, it is already the post link of plastic bag production, and it can basically be formed

4:这里要说一点，塑料袋制作的工序都是分开的，并不能都能及时的衔接，所以一把塑料袋生产周期都在10天左右。

4: It should be said here that the production processes of plastic bags are separated and can not be connected in time. Therefore, the production cycle of a plastic bag is about 10 days.
