1. Safety
Mainly refers to the strength of the container bag. When designing, the packaging volume, the weight of the load and the number of packaging units should be considered. The distance of transportation and the number of handling times should also be considered, as well as the transportation tools and methods used. In the national standard GB/T10454-2000 for container bags, the technical index requirements for the base fabric and slings of the container bag are strictly stipulated. From a safety perspective, it is clarified that the structure of the container bag is all bottom hanging structure. The safety factor must reach 1.8.
2. Storage
The materials and proportions should be reasonably selected according to the user's use conditions. The anti-aging ability of plastic products under sunlight exposure is a more concerned issue, and it is also a problem often encountered in the actual use of container bags. Pay attention to the use of anti-purple agents and the selection of materials during the production process.
3. Usability
When designing bulk bags, we must fully consider the specific ways and methods of using bulk bags by customers, such as lifting, transportation methods, loading material performance, etc. In addition, we must also consider whether it is food packaging and whether it is non-toxic and harmless to the packaged food.
4. Sealing
Different packaging materials have different sealing requirements. For example, powders or toxic items, 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 for airtightness. Therefore, when designing bulk bags, pay attention to the impact of the base fabric laminating process and sewing process on sealing.
