Big bags are a product that is widely used in the transportation industry, and this type of product is also very common in our lives. Ton bags play a very important role in transportation, because we all know that products need to be packaged well during transportation, so that the overall space will be reduced, and the amount of products can be packaged according to the actual situation.
1. Determine the outer size and shape of the big bag, determine the outer size according to the filling volume of the big bag, and determine the shape of the big bag according to the requirements of use and transportation.
2. Determine the material of the ton bag, and determine the material of the ton bag according to the product characteristics, storage and transportation environment, and the life of the ton bag.
3. Determine the processing and production method of the ton bag. In addition to cutting the material according to the size of the bag when making bags from blanks, the key is to determine and process the seams of the bag body.
4. Ton bags are mostly made of synthetic fiber weaving without glue or plastic coating. In order to reduce costs, in recent years, polystyrene, polyethylene or polyester filament weaving are mostly used to make ton bags.
5. Generally, the seams can be processed by sewing or bonding, but they should be compatible with the material of the bag. Generally, plastic cloth needs high-frequency heat-sealing bonding, chemical fiber cloth needs sewing, and rubber cloth needs bonding or bonding. Sulfur thermal bonding method.
6. It is easy to suture the seam, but there is a possibility of local tearing, needle removal and thread breakage. Adhesive joints should be ensured to be firm and reliable, and generally need to be tested for adhesive strength. Regardless of the method used to assemble the container bag, the strength of each seam must be equivalent to the strength of the base fabric.
