When choosing woven fabric for container bags, choose flat, no holes, no damage, the weight of the items it holds is relatively large, if there is damage or defect, it will directly affect its carrying capacity. The container bag manufacturer tells you that when choosing the cloth used in the container bag, one of the most important aspects is the tensile strength of its plastic woven wire. At the same time, when making and selecting these woven cloth, its durability, durability The size of the grinding capacity and the requirements of the storage environment are one of the most important aspects.
Container bags are used as export packaging to ensure that the export goods are effectively protected during loading, unloading, transportation and storage, and the goods are transported to the destination in good condition. Therefore, the design of container bags must meet four main points, namely, safety, storage, usability, and sealing.
According to the technicians of the big bag, ultraviolet rays will affect the quality of the bag, because the most exposed to the big bag no matter in storage, transportation, use, etc. is sunlight. The ultraviolet rays in the sun have high energy and can promote the production of free radicals and hydroxides. This will cause the breakage of the molecular chain in polypropylene, so the big bag will show weakened tensile ability and so on. In addition, the differences in local temperature and humidity should also be considered.
In the design, the packaging volume, the weight of the contents and the number of packaging units should be considered, as well as the distance of transportation and the number of times of transportation, as well as the means of transportation and transportation methods to be used. In the GB/T10454-2000 national standard for container bags, the technical index requirements for the base fabric and straps of container bags are strictly stipulated, and from the perspective of safety, it is clarified that all container bag structures are bottom hanging structures. The safety factor must reach 1.8.
Preservability should be based on the user's use conditions, reasonable selection of materials, and a reasonable ratio. 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 agent and the selection of materials during the production process.
When designing container bags, it is necessary to fully consider the specific ways and methods of customers using container bags, such as lifting, transportation methods, loading material performance, etc. In addition, it is necessary to consider whether it is food packaging, and it must be considered non-toxic and harmless to the packaged food.
