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

眾所周知，塑料袋是塑料薄膜制成的，那么塑料薄膜又是怎樣形成的呢?這是塑料袋制作步:吹塑。吹塑是將采購的原料塑料顆粒通過吹塑機吹制成塑料薄膜

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。前一步講了吹塑，形成訂單規格的薄膜后，要著手印刷了。根據所需印刷圖案先要制版，一般制版和吹塑是同步的，也是吹塑完成后，版子也應該制好了，通常制版需要4天時間左右。

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.

塑料袋印刷分單面或雙面以及顏色區分。比如購物袋，一般以單面或雙面一兩個顏色為常見，一個顏色對應版，但并非雙面顏色相同可以共版，這是不行的，譬如雙面各兩個顏色得制作4塊版。塑料袋印刷一般為凹印，采用多為銅板，也有膠版。

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.

印刷機組安好版子和卷料，調好油墨，可以印刷了

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

3:根據不同的塑料袋種類，印刷好的塑料薄膜制袋方式不一樣。有需要邊的、需要復合的、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...

但是到了這一步，已經是塑料袋制作的后環節了，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:這里要說一點，塑料袋制作的工序都是分開的，并不能都能及時的銜接，所以一把塑料袋生產周期都在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.
