How Much is the Suitable Amount of Hot Melt Glue on the Seal of a Poly Mailer?
In recent years, the Internet industry has developed rapidly. Tmall, Taobao, JD.com, Vipshop, Pinduoduo, Suning and other platforms are emerging. During each traditional festival, Western festivals or emerging e-commerce festivals such as Double Eleven and Double Twelve, these platforms will vigorously promote it, making them carnival places for most people. Online shopping is convenient and affordable, making it an essential entertainment item for people today.
With the continuous growth of online shopping transactions, not only the Internet industry has developed the express delivery industry, but also express delivery companies have also developed rapidly. Due to the increasing number of express companies, poly mailers are used as packaging consumables. The number of courier bags used is very large. To use poly mailers, you need to seal them. The best way to seal the poly mailers is to use hot melt glue.
Each express bag has a seal at one end. After the product is loaded, apply a long line of glue on the sealing position and cover with a release film. After the release film is removed, the espresso bag will be quickly glued to the table and sealed to protect the bag Items in.
What is the amount of hot melt glue on the seal of the express bag? The amount of coating will also affect the production cost to a certain extent, so the proper thickness of the glue becomes very important.
In order to save costs, some manufacturers will cover very thin glue line, the thickness of which is less than 0.1mm, tell you: the consequences of this coating is difficult to predict, may be due to joining the trade union. If the force is insufficient, the bag mouth will loosen, causing invaluable loss to the user; and the glue is too thick to save profits. Therefore, according to Fengqi's experience, the appropriate thickness is 0.2-0.3mm or the amount of glue is 100-200 GSM, which can ensure the sealing quality of the bag mouth and the sealing performance of the bag mouth. The glue will not be too much, so the production cost would not be too high.
