1. Clarify the outline specification and appearance design of the ton bag, specify the outline specification according to the filling volume of the ton bag, and clarify the appearance design of the bag according to the application and transportation regulations.
2. Determine the raw material of the ton bag, and determine the raw material of the plastic woven bag according to the characteristics of the product, the natural environment for storage and transportation, and the service life of the plastic woven bag.
3. Clarify the production and processing practices of ton bags. When making packaging bags with blank materials, in addition to cutting boards according to the specifications of the bags, it is important to define and process the seams of the bag body.
4. Ton bags are mostly made of man-made fiber weaving mechanisms, and do not dispense glue or coat plastic. In order to control costs, in recent years, polystyrene, high-pressure polyethylene or polyester silk weaving mechanisms are mostly used for plastic weaving. bag.
5. Generally, the seams can be processed by sewing or bonding, but they should be consistent with the material of the bag. In general, the plastic film should be hot-melt bonded at high frequency, and the chemical fiber loom should be stitched properly. Legally, the vulcanized rubber cloth is bonded or vulcanized by hot bonding.
6. The seam of the suture is simple and easy, but some tear-off masks, needles and disconnections may occur. The bonded joints should be firmly secured, and the bond strength test is generally required. No matter which method is used to assemble the woven bag, the strength of each seam must be equal to that of the needle-punched non-woven fabric.
