The process of processing convenient bags by Yingkou convenient bag manufacturers

Convenience bags can often be seen in our lives. It can be said that our life is inseparable from convenient bags. In fact, the production process of commonly used convenience bags is also very simple. The Yingkou supermarket bags are usually used in supermarkets. The production process of the packaging bags is basically the same. The processing of the convenient bags can be divided into four processes: granulation, blow molding, pressing bags and bag cutting. Today we will introduce in detail how the convenience bags are formed in the convenience bag manufacturers. :

1. Granulation process: The raw material for convenient bag processing is a careful plastic granule. The waste material should be sent into the granulator and cut, heated and melted, and extruded into small particles of about 0.3CM.

2. Blow molding process: The blow molding process is divided into heating and melting part, blowing part and rewinding part. First, the plastic pellet raw material processed in the previous step is poured into the blow molding machine and melted at high temperature, and the screw will rotate under the screw. The plastic melt is evenly stirred and sent to the machine head. The plastic melt (melted plastic pellet material) is extruded from the ring of the machine head under high pressure to form a plastic tube with a thickness of 0.1 cm, and then blown evenly on the nose blower. Under the movement, a thin and convenient bag is formed. Finally, the bag is fed into two tightly rolling rollers. The rotation of the two rollers will facilitate the extrusion and pressing of the air in the bag to become the most original strip. The bag, then the printing equipment will facilitate the printing of the bag, and finally the winder will roll it into a cylindrical ball, and the key step is completed;

3, the process of pressing the bag: the blown bag is put into a bag machine and cut into a convenient bag of specific specifications, and the two ends of each bag are sealed, and then the convenient bag is automatically put into a few hundred;

4. Bag cutting process: Put the convenient bag under the knife of the bag cutting machine, and cut off the middle part of the convenient bag under the high pressure of the bag cutting machine to form a handy hand.
