Previously, packaging factories have introduced some paper bags like camera paper bag manufacturers, which are mainly large and medium-sized electronic products. Their technology is often used to make camera bag, which is no less than that of packaging boxes. On the contrary, the formation of a hand-held bag completely depends on the material of the paper bag itself, and there is no other material that can be attached to form it. However, in addition to the test of materials and glue, It’s also a great experience.
Why take the camera paper bag manufacturer as an example, because their handbags are generally customized in large size, and the weight of the loaded products also has a certain weight, which is really a test of the use of glue for large-size handbags. The large-size paper bags made by the camera paper bag manufacturer mean that knives are needed at both the bottom and the middle of the two sides of the paper bag, The back cover is completely bonded by glue. There is such a large paper bag without glue. Usually, this paper bag will contain products with an outer box, which will evenly distribute the weight of the product at the bottom of the paper bag. At first glance, it can indeed play a protective role for the load-bearing of the whole paper bag, but in fact, it is not. When the long-term stress surface is under pressure, it will turn around, the only bonding point, The position sealed with glue will appear as a problem, because it still has to bear the tearing weight pressure from the four corners of the whole paper bag at the bottom.
In this case, the load-bearing of the paper bag is a great test. If the glue at the bottom of the paper bag is not used at the appropriate point, the paper bag will collapse directly. What’s more terrifying is that the paper bag is generally not sewn manually, and occasionally there are problems. The camera paper bag manufacturers generally form it in large quantities by machine at one time, and the amount of glue is so much every time, which means that this batch of paper bags, May face the risk of scrap.
In addition to the camera bag manufacturers’ unique views and attention on the use of glue, there is also a problem that some paper bag manufacturers directly use a large amount of glue to ensure the stability of the bottom in order to solve the problem of glue consumption at the bottom of the paper bag. Then the problem will come, and the drying problem will appear. The drying problem not only affects the storage and transportation of the paper bag, but also a very serious problem is the smell of incomplete drying of the glue, This is very serious. Another factor that can always stabilize this odor near the industrial zone is that the masters of some manufacturers do not have good technology and do not control the glue well, resulting in excessive use. When the odor appears, they have to hang the paper bags in a ventilated place to remove the odor. At this time, it is the unwelcome smell that we often smell.
