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.When maintaining high-performance operation of the hot melt adhesive machine, you can take many measures to reduce downtime and improve system performance. Please remember that downtime equals production loss. 1) Apply hot melt adhesive at the correct temperature. Using the correct settings can avoid many troubles. You may also want to try using a metallocene […]
In our industry, it is crucial for EVA hot melt adhesive to handle packaging materials correctly – they must be removable and should not damage the finished product, production process, or environment during recycling. However, for adhesive companies, producing glue today is equally important, as it contributes to a more sustainable future for packaging and […]
The importance of product packaging is twofold: it helps maintain the safety and reliability of the contents and provides consumers with attractive products. The packaging process is one of the most important stages in product manufacturing and distribution. With decades of experience as a packaging hot melt adhesive manufacturer, Senlai Hot Melt Adhesive is delighted […]
Book edge glue is an important but often overlooked application of book binding glue. Simply put, it refers to using a thin layer of hot melt adhesive to bond the inside of the cover to the first, last, or final page of the book. Although side bonding is much smaller in volume than spine bonding, […]
