What quality standards should be met in the production of container bags
Container bags are light in weight, but they have large capacity, so they are also called ton bags, which are mainly used in unit transportation. Large capacity, but light weight, so the quality of container bags must be very good to meet the transport needs. Then let's take a look at the quality standard of container bags.
1. Container bags should be made in strict accordance with the requirements of the Skills List for Container Bags Making. The appearance should be beautiful, wireless head, no pollution, no damage, clear printing image of container bag, accurate orientation.
2. The main body and the bottom seams should be double-folded. There are three sewing lines with a width of about 2CM. No obvious wrinkles are allowed. The lines and threads are even and not stacked. The stop needle holds the needle up.
3. Use sewing threads as needed. No stacking, leaking, floating, leaking, and hanging are allowed. The upper and lower threads are tightened together.
4. The starting and stopping needles of packaged bags must coincide with 5CM on the same suture line (stop needle presses the starting needle). Strengthen the cloth starting needle on the upper left, the stitching thread and the distance edge are 1CM, and the sewing material bag is the starting needle and the distance edge is 1CM. Start needle and pour needle.
5. Sewing chrysanthemum-shaped mouth stiffening cloth, string position 3CM, remaining position 2CM, cover cloth sewing 10CM. 11. Joints at the bottom of the top with the inmost seams pressing the top. The bottom inner circle sign is not allowed to cross. When sewing the second channel, it is about 0.5CM away from the first channel, so stacking is not allowed.
Quality is the life of container bags. Only living products can be given mission, so products must meet the basic quality requirements.
