Bulk bag designed to be strictly enforced GB/T10454-2000 national standards. Bulk bag as an export packaging, to ensure that exports of goods handling, transportation and storage process of effective protection for loading goods, security and ease of the goods to the destination. Therefore, the bag design must meet the four elements, namely, security, custody of, use, sealing.
a. Security
Mainly refers to bulk bag strength. To be considered in the design of packaging volume, weight and packaging contain materials units (number), we also consider the distance from transport and handling of the number of times, using what means of transport and transport methods. The GB/T10454-2000 bulk bag national standards, the stringent requirements of the tons of bags of fabric and harness technical requirements, from a security point of view, defined the structure of all the bulk bag hanging at the end of the structure. 1:6 safety factor must be met.
b. Preservation
Should be based on user conditions of use, reasonable selection of materials, a reasonable proportion. Plastic products in the sun exposure under the anti-aging ability is more concerned about the issue, but also tons of bags in the actual use of the process of frequently encountered problems. In the production process agents Note that the use of anti-purple, and material choice.
c. Usability
Bag in the design, we should give full consideration to customers to use bulk bag concrete ways and means, such as the mention hanging, mode of transport, loading material properties. Furthermore, we need to consider whether for food packaging, to consider the right of the packages of food non-toxic and harmless.
d. Tightness
The different packaging materials, sealing different requirements. Tons of bags, such as powder or toxic substances, for fear of contaminated items very strict requirements on the sealing performance, easy to damp or moldy materials on air tightness have special requirements. So, when in the design of t bag, pay attention to consider the fabric coating process and sewing process on the impact of tightness.
