Preservation: The jumbo bag should be based on the user's use conditions, and the material should be selected reasonably and the ratio should be reasonable. The anti-aging ability of plastic products under sunlight exposure is a problem of concern at present, and it is also a problem often encountered in the actual use of container bags. Pay attention to the use of anti-purple agent and the selection of materials during the production process.
Sealing: Different packaging materials of ton bags have different sealing requirements. For example, powder or toxic materials, and items that are afraid of contamination have very strict requirements on sealing performance, and materials that are prone to moisture or mildew also have special requirements on air tightness. Therefore, when designing large bags, pay attention to considering the influence of the base fabric lamination process and sewing process on the airtightness.
Safety: mainly refers to the strength of the big bag. In the design, the packaging volume, the weight of the contents and the number of packaging units should be considered, as well as the distance of transportation and the number of times of transportation, as well as the means of transportation and transportation methods to be used. In the national standard for container bags, the technical index requirements for the base fabric and straps of container bags are strictly stipulated, and from the perspective of safety, it is clarified that all container bags are bottom-hanging structures. The safety factor must reach 1.6.
In fact, professional jumbo bags are designed and manufactured according to certain basis, such as: safety, storage, usability and sealing characteristics.
