The design of container bags must strictly comply with the national standard GB/T10454-2000. As an export packaging, container bags should ensure effective protection of the loaded goods during loading, unloading, transportation, and storage, and transport the goods to the destination in perfect condition. Therefore, the design of container bags must meet four key points, namely safety, storage, usability, and sealing.

1. Security

Mainly refers to the strength of the packaging bag. When designing, it is necessary to consider the packaging volume, weight of the contents, and number of packaging units, as well as the distance of transportation and the number of handling times, and the choice of transportation vehicles and methods. In the GB/T10454-2000 national standard for container bags, strict technical specifications for the base fabric and sling of container bags are specified. From a safety perspective, it is clarified that all container bag structures are bottom suspended structures. The safety factor must reach 1.8.

2. Custody

Materials should be selected and proportioned reasonably based on the user's usage conditions. The anti-aging ability of plastic products exposed to the sun is a concern, which is also a problem often encountered in the actual use of container bags. Pay attention to the use of anti UV agents and the selection of materials during the production process.

3. Usability

When designing container bags, it is necessary to fully consider the specific ways and methods in which customers use container bags, such as lifting, transportation methods, loading material performance, etc. In addition, it is necessary to consider whether it is food packaging and whether it is non-toxic and harmless to the packaged food.

4. Sealing performance

Different packaging materials require different sealing requirements. Materials such as powders, toxic substances, and items that are afraid of contamination have very strict requirements for sealing performance, and materials that are prone to moisture or mold also have special requirements for airtightness. Therefore, when designing container bags, attention should be paid to the influence of the base fabric lamination process and sewing process on the sealing performance.
