Features of ton bags:
The use of big bags has high requirements for automation, which can save costs, save time and labor, and facilitate transportation and product storage. Therefore, ton bag manufacturers have stricter quality requirements.
Structural requirements for big bags:
The waist hoop should be sewn on the outside of the sling to enhance the bearing strength of the sling, and the strength of the waist hoop should be more than two or two times the strength of the base fabric.
Sewing technology of ton bags:
Including these aspects: the tensile strength of the bottom seam should reach more than 42% of the strength of the base fabric; the tensile strength of the side seam should reach more than 67% of the strength of the base fabric; Straight, no broken needles, no floating threads, no loose stitches, no less than three stitches at the starting and dropping positions, the length of the suspenders should be equal, the overlapping seams should be even and straight; and there should be no obvious lack of warp Less dimension, no obvious defects, no obvious stains on the surface, clear printed pattern on the bag body, and accurate position.
Note: For the sewing technology of large bags, it is also very important that for bags with side seams, they should be sewn under any sling to enhance the side seam strength of the container bag.
Features of big bags:
1. Simple structure, light weight, can be folded to save space, small space occupied, low price, and can be stacked for storage.
2. The load capacity is between 0.5-3T, the volume is between 500-2300L, and the safety coefficient can be designed according to the needs of users at 3:1, 5:1, and 6:1.
3. According to the content, the goods are divided into two categories: bulk goods container bags and small package goods container bags, which are suitable for one-time use and turnover use.
4. According to the shape, it can be divided into three types: round container bag, square container bag and U-shaped container bag.
5. According to the lifting structure, there are top hanging type, side hanging type and bottom hanging type, and there are generally inlet and outlet ports.
Precautions for purchasing large bags:
When we buy, we can judge from the color and feel. Container bags produced from pure materials often have transparent light, and the feel is also smoother without the feeling of burrs. Moreover, the proportion of pure material container bags will not be very large, because pure material products can be stretched very long during the production process. If you use a cored container bag, the specific gravity will be much larger than this value, which is also due to the addition of miscellaneous materials. We still choose container bags made of pure materials, and the performance will be better.
