You must want to know how to detect common composite bags.biodegradable clear mailing bags Vendor

　　The composite bag zipper has good obstruction, thermal sealing, moisture resistance, and is acid -resistant, alkaline and wear -resistant, so it is widely used in food packaging. With the increasing requirements for the quality requirements of soft packaging composite bag zippers, the quality testing of packaging companies on soft packaging composite bag zippers has also paid more and more attention.

　　Appearance visual inspection includes projects such as the flatness and transparency of composite bag zipper. It is mainly used to detect whether there are obvious abrasions and pinhole on the surface of the composite bag zipper, and whether there is pollution at the seal.

　　Place the center of the composite bag zipper, align the 40W solar light gently, and use the reflection light on the surface of the zipper surface of the composite bag to clearly find out whether the surface of the composite bag zipper is scratched or traces. Essence If the drawing is serious, you must find the fault according to the actual situation, and reduce the impact to the lower point to ensure the quality of the product. By observing that the drawing phenomenon we found is mostly caused by the non -cleaning of the guidance roller of the bag making machine, we must ensure that the guide roller is clean. In addition, no rotation of the guide roller will also cause brushes to draw a composite bag zipper. The reasons for the non -rotation of the guide roller are mostly caused by the lack of oil in the bearing, so good lubrication is the fundamental condition for bearing rotation.

　　Composite bag zippers are mainly used for chemical, food, medicine, tea, high -pure metal, electronic original devices, precision instruments, large machinery, and general packaging or general packaging.
