1. Security

Mainly refers to the strength of the container. The packaging volume, the weight of the load and the number of packaging units should be considered in the design. Also consider the distance of the transportation distance and the number of transportation times, and what kind of transportation and transportation methods should be used. In the GB/T10454-2000 container bag national standard, the technical requirements for the base bag and sling of the container bag are strictly defined. From the safety point of view, it is clear that the structure of the container bag is all the bottom hanging structure. The safety factor must be 1.8. Ordinary container bag

2. Custody

According to the user's conditions of use, reasonable selection of materials, a reasonable ratio. The anti-aging ability of plastic products under sunlight exposure is a problem of concern, 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 choice of materials during the production process.

3. Usability

When designing a container bag, it is necessary to fully consider the specific methods and methods used by the customer to use the container bag, such as lifting, transportation, loading material performance, etc. Also consider whether it is food packaging, and consider being non-toxic and harmless to the packaged food.

4. Sealing

Different packaging materials, different sealing requirements. For example, powder or toxic materials, and materials that are afraid of being contaminated have strict requirements on sealing performance. Materials that are prone to moisture or mildew have special requirements for air tightness. Therefore, when designing the container bag, pay attention to the influence of the base film coating process and the sewing process on the sealing performance.
