The design of chemical tonnage bags should strictly comply with national standards. Export packaging uses special tonnage bags for powders, particles and solid blocks to ensure that the loaded cargo is effectively protected during loading, unloading, transportation and storage, and is safely and completely transported to the destination.
In the design, the manufacturer of tonnage bags should consider the amount of tons of packaging, the loading weight and the number of packaging units, the transportation distance, the number of loading and unloading times, and the mode and method of transportation. The national standard has strict regulations on the technical index requirements of the base cloth and the sling, and from the safety point of view, the structure is the bottom lifting structure.
The packaging bag should be reasonably selected and proportioned according to the user's use conditions. The anti-aging ability of plastic products under sunlight is a concern at present. Pay attention to the use of anti-violet agents and the selection of materials in the production process. The design fully considers the specific ways and methods of customers using ton bags. In addition, we should also consider whether food packaging, which is non-toxic and harmless packaging of food.
Due to the different packaging materials of the chemical ton bag, the sealing requirements are also different. For example, powder or toxic substances and substances that are afraid of contamination have very strict requirements for sealing performance. Therefore, when designing ton bags, attention should be paid to the effect of substrate coating process and sewing process on sealing performance.
