When designing a ton bag, the weight of the cargo to be loaded should first be clarified, and the volume of the ton bag should be determined based on the specific gravity of the materials included. It is convenient for shipping bulk powdery materials. It has the characteristics of large volume, lightweight, and easy loading and unloading. It is one of the common packaging materials. The design of ton bags is crucial to the use of ton bags, so what should we pay attention to when designing ton bags?
1. Improve monofilament strength
To ensure the strength of the base fabric of the ton bag, the tensile strength of the flat yarn should be increased. In the actual production and processing process, the amount of filling masterbatch should be strictly controlled, generally around 2%. If too much masterbatch is added, or recycled materials are added, the strength of the base fabric will be reduced.
2. Sling material selection
In the design of ton bag manufacturers, the selection of sling materials is crucial. In the actual design of ton bags, firstly, the loss of strength of the sling caused by the sewing process must be considered; secondly, the lifting method must be considered. When designing slings for ton bags, two-ring or four-ring methods can be used to increase the tensile strength.
3. Add additives to extend the service life. In order to improve the anti-aging ability of plastic ton bags under sunlight, a certain amount of anti-violet agent and stabilizer should be added during the flat yarn stretching process. Determine the amount of addition based on the service life of the ton bag.
