How to distinguish the quality of book binding glue? The hot melt adhesive used in books is divided into backing adhesive and edge sealing adhesive According to the thickness of different materials of paper and books, book adhesives with different viscosities and flow effects can be used to complete the bonding work of book pages.
Hot melt adhesive for books is already very mature, and both thick and thin books can be glued together. However, many people do not pay much attention to the application of hot melt adhesive in their daily lives.
How to distinguish book binding hot melt adhesive:
Firstly, the same paper can be used and different machine speeds can be used to test the glue. Through this testing method, the bonding effect and tensile strength of this hot melt adhesive can be determined. On the same machine, test the bonding effect and tensile strength of this hot melt adhesive with different papers at the same speed. Put the glued paper in the refrigerator and freeze for about 1-3 hours. Take out the paper in batches, separate the glue from the middle, observe whether the paper is damaged or brittle, and determine the weather resistance of the glue. Of course, for book hot melt adhesive itself, it is necessary to observe whether the adhesive has impurities, whether there are bubbles, and the viscosity of the adhesive during heating to determine the quality of the adhesive.Hot melt adhesive is a type of thermoplastic that melts into a solid state by heating and applying temperature. When the adhesive begins to solidify (heat loss) before the material is bonded, cold bonding occurs, which can lead to bonding failure. Usually, it appears to be firmly adhered after bonding, but the bonding strength may […]
In the past few decades, the printing industry has undergone many changes. With the rise of digital media, publishers have changed the way they conduct their business. Although e-books and audiobooks are popular, books have not disappeared and readers around the world still crave them. On demand printing is changing the way the publishing industry […]

Let’s take a look at the common hot melt adhesive problems that manufacturers face today and explore possible solutions. Problem 1: UsingHot melt adhesiveToo little If your packaging […]
Why does pearl cotton hot melt adhesive have wire drawing? During the process of gluing pearl cotton with a drum hot melt glue machine, some customers may find that the hot melt glue has a wire drawing phenomenon. The wire drawing of the hot melt glue not only affects the construction efficiency, but also affects […]
