In recent years, the Internet industry has developed rapidly. Tmall, Taobao, JD.com, Vipshop, Pinduoduo, Suning.com and other platforms have increased. Every traditional festival, Western festival, or informal festivals such as Double 11 and Double 12, these The platform will vigorously promote it, making it a carnival place for most people. Online shopping is convenient and affordable, so it is now an indispensable entertainment item for people. Zhengbang editor is also a super netizen.

With the continuous growth of online shopping transactions, not only the Internet industry has developed, but also express delivery companies such as SF Express, Zhongtong, EMS, Debon, Shentong, Yuantong, Yunda, etc. have also grown rapidly. Due to the growing number of couriers, courier bags are used as packaging consumables. The amount of courier bags used is huge. The use of courier bags requires courier bags to be sealed.

There is a seal at one end of each express bag. A long glue line is coated on the sealing position and covered with the release film. After the goods are loaded, the release film will be removed and the express bag will quickly stick Sealing, to protect the contents of the bag.

So how much is the amount of hot melt adhesive at the seal of the express bag? The amount of coating also affects the production cost to a certain extent, so the appropriate thickness of the glue becomes very important.

In order to save costs, some manufacturers will apply the glue line very thin, the thickness of which is less than 0.1 mm, so the consequences of coating are difficult to predict, and the phenomenon of loosening of the bag mouth may occur due to insufficient adhesion, which may cause impossibility to the user. Estimated loss; but the glue is too thick to save profits. Therefore, based on Zhengbang ’s experience, a thickness of 0.2-0.3 mm or a glue amount of 100-200 GSM is more appropriate, which can ensure the sealing quality of the bag mouth, and the amount of glue will not be too large, so the production cost is not too much. high.

Bond Materials' express bag sealing hot melt adhesive has stable performance, good low temperature initial adhesion, strong initial peel strength and good high temperature resistance, suitable for PE, PP and other fast bag sealing, bubble bag sealing, fast bonding at room temperature Connection, low temperature bonding is firm, can be applied to the high temperature in the container shipping across the ocean. The goal of Zhengbang (Guangzhou) New Materials Co., Ltd. is to produce the most satisfactory products for users according to the requirements of customers, to share unlimited value with innovative technology, and to create the future together.
