The binding of early books is mostly line ordering, which is not only time-consuming and labor-intensive, but with the development of the adhesive industry, the binding has gradually replaced the line order and became the mainstream of book binding.

Mainstream. The books that are now seen in bookstores are basically wirelessly bound with hot melt adhesives. This shows the popularity and popularity of hot melt adhesives in bookbinding applications. However, although it has been a long time since the application of bookbinding hot melt adhesives in China, the application level of hot melt adhesives in book binding is not high due to various factors of the book industry market environment. In order to control the cost of the bookbinding manufacturers, the hot melt adhesive used is an unstable product, which affects the book binding effect and greatly shortens the life of the book. At present, in bookbinding applications, EVA hot melt adhesive is the most used type of rubber in China, but because of its low melting point, it limits the use of EVA hot melt adhesives. Polyurethane hot melt adhesive is an upgraded version of EVA hot melt adhesive. It is more suitable for bookbinding applications. The good elasticity and high strength are the characteristics of polyurethane hot melt adhesive. Nowadays, there is a kind of reactive polyurethane hot melt adhesive on the market. This hot melt adhesive has high properties, heat resistance, cold resistance, and no fear of moisture. The environment has minimal impact on it and its penetration on book pages. Very good, strong adhesion, so the amount can be reduced each time the glue is applied, thus saving the cost of using hot melt adhesive. Reactive polyurethane hot melt adhesives are the best choice for bookbinding applications. This article is edited by Glue Dots hot melt pressure sensitive adhesive.
