What properties does a qualified container bag need to have | Qingdao Johson Packaging

Although ton bags can ensure that the packaged goods are not damaged during loading, unloading, transportation and storage. But the prerequisite is that the quality of the ton bag is qualified. So, what properties does a qualified container bag need to have?

1. Firmness mainly refers to the strength of the ton bag. When designing, we must consider the packaging volume, weight of the contents and packaging units (number), as well as the distance of transportation and the number of handling times, as well as the means of transportation and transportation methods used.

2. Storageability, materials should be selected reasonably and the process ratio should be reasonable according to the user's usage conditions. For example, the ability of plastic materials to withstand sunlight exposure is a major indicator that determines the quality of ton bags. It is also a problem that is often encountered in the actual use of ton bags. Therefore, attention should be paid to the use of anti-UV agents and resistance to ultraviolet radiation during the production process. Material selection.

3. Practicality: Full consideration must be given to the specific ways and methods used by customers to use ton bags, such as lifting and transportation methods and the performance of the loaded materials. In addition, you must also consider whether the packaged goods are food and ensure that there is no adverse impact on the packaged food.

4. Sealing performance. Different materials to be packaged have different sealing requirements. For example, powders or toxic items, or items that are afraid of being contaminated, have strict sealing performance requirements. Special materials that are prone to moisture or mildew also have different requirements for air tightness. Therefore, when designing ton bags, pay attention to the impact of the base fabric lamination process and sewing process on the sealing performance.
