1. Determine the outline size and shape of the container bag, determine the outline size according to the filling amount of the container bag, and determine the shape of the bag according to the requirements of use and transportation.
2. Determine the material of the container bag, and determine the material of the container bag according to the product characteristics, storage and transportation environment and the life of the container bag.
3. The processing method of the container bag. In addition to cutting the material according to the size of the bag, the key is the determination and processing of the seam part of the bag body when making bags from blanks.
4. Most of the container bags are made of synthetic fiber fabrics, and no glue or plastic is applied. In order to reduce costs, in recent years, polystyrene, polyethylene or polyester filament fabrics are mostly used to make container bags.
5. Usually, the seam can be processed by stitching or bonding, but it should be adapted to the material of the bag. In general, plastic cloth needs high-frequency heat bonding, chemical fiber cloth needs stitching, and rubber cloth is glued or used. Sulfur thermal bonding.
6. The suture seam of the container bag is simple and easy, but there is the possibility of partial tearing, needle removal and thread breakage. Adhesive seams should be secure and generally need to be tested for adhesive strength. No matter what method is used to make the container bag, the strength of each seam should be equal to the strength of the base fabric.
