Ton bags are also called container bags or space bags. With the growing demand for ton bags in domestic and foreign markets, my country's imports and exports of ton bags have further increased. At the same time, the international market has become more stringent in terms of the quality of ton bag products. How to improve the quality of ton bags, select appropriate industrial raw materials, and reasonable process ratios; under the premise of implementing national standards, combined with the actual situation of the enterprise, design high-quality ton bags is an important issue facing all ton bag manufacturers, and several issues that need to be paid attention to in the design of ton bags.
Ton bags are made of polyolefin resin through a drawing and weaving process, and then cut into tubes or sheet substrates of varying sizes after coating, and then the substrates are sewn into round or square bagged products according to design requirements. Ton bags are flexible transport packaging containers with the excellent properties of plastics such as lightness, softness, acid and alkali corrosion resistance, moisture resistance, and impermeability; they have sufficient strength in structure and are firm and safe, easy to load and unload, and adapt to mechanized operations. They can be widely used in the packaging of various powdered, granular, and blocky items such as chemicals, cement, grain, and minerals.
The design of ton bags must strictly follow the national standard GB/T10454-2000. As export packaging, ton bags must ensure that the exported goods are effectively protected during loading, unloading, transportation, and storage and that the goods are safely and instantly transported to the destination. Therefore, the design of ton bags must meet four key points, namely safety, storage, usability, and sealing.
Mainly refers to the strength of ton bags. When designing, the packaging volume, load weight, and packaging unit (number) must be considered, as well as the distance of transportation the number of times of handling, and the type of transportation tools and methods to be used. In the national standard GB/T10454-2000 ton bags, the technical indicators of ton bag base fabrics and slings are strictly stipulated. From a safety perspective, it is clarified that all ton bag structures are bottom-hanging structures. The safety factor must reach 1:6.
A reasonable selection of materials and reasonable proportions should be based on the user's use conditions. The anti-aging ability of plastic products under sunlight exposure is a problem that is currently of great concern, and it is also a problem that ton bags often encounter in actual use. Pay attention to the use of anti-purple agents and the selection of materials during the production process.
