Roduction Process Of Pp Woven Sugar Bag
- The production process of cheap PP woven bags can be encapsulated in the following stages: Plastic beads - Threads - Weaving - PE coated - In Flexo - Finished products. The main steps to creating a complete product include:
- Making PP yarn: Put the PP plastic beads into the hopper of the fiber generator. Thanks to the suction from the suction machine, PP granules are fed into the extruder. Here the melting process takes place and the extrusion screw of liquid plastic into the mouth of the mold has the length and width can be adjusted as required. The formed plastic film continues to flow through the shaped cooling water tank. The cutter shaft splits the plastic film into filaments with a width of 2-3 mm. After having the yarn of the required size, the heating element will help stabilize the yarn and then put it into a spinning machine. In the process of creating yarn, waste products are recovered, cut small and returned to the extruder.
- Weaving PP fabric: After having PP yarn according to the available size, the yarn rolls are put into a six shuttle circular loom. Here, the yarn is woven into a tube and then rolled into PP.
- Coated with PP film: Forklift transports the PP fabric roll to a film coating machine to coat with a thick PP layer of 30. After the moisture-proof fabric is coated with a film to increase cohesion, the PP fabric rolls to take away printing.
- Printing on woven PP bags: Normally for normal woven PP bags, or PE-coated bags, people conduct printing by different printing technologies, in which OPP film is Professional and most beautiful.
- Cutting finished products and packaging: PP woven rolls go through the folding system and then cut the finished products. People can sew first and then print later or print first and then sew.

What is the Difference between PP Woven Sugar Bag Printing and Paper Printing?
- Printing ink is different. The printing ink of pp woven sugar bags is special plastic ink, which has strong adhesion on the woven bags and is not easy to fall off. The printing ink of ordinary paper will fall off when it is rubbed on the woven bags. The printing ink on paper can not easily fall off and dry quickly when it is eaten into the paper.
- Different printing methods. For the pp woven sugar bag printing, if the number is small, we generally use flat screen to print. Plate-making is convenient and flexible. It can be printed either by machine or by hand. The service life of screen plate is short, and the missing version usually occurs from 1 to 20,000 times, which requires revision. The maximum may not exceed 30,000 times. If the quantity is large, it can be printed by metal screen printing or offset printing, which belongs to large machines. The printing speed is fast and the service life of the plate is long, but the printing process is relatively complex. About one edition can be printed more than 100,000 times. Flat screen printing and metal screen drum printing are not suitable for color printing. Generally, they are only used for monochrome or two-color printing. Otherwise, the printing process is complex and the efficiency is low. Offset printing can be used for color printing.
- PP woven sugar bag printing need to be aired or dried for the sake of the ink, otherwise the printed products are easy to adhere. Paper printing technology is developing very fast, so the high-speed printing and color printing has reached a very high level.
