What are the uses of hot melt adhesive? In recent years, with the rapid development of e-commerce, logistics, packaging, labeling and other related industries have also experienced significant growth. The labeling industry and adhesive industry are driven by these industries and are areas that people see, use, and come into contact with every day. But […]
Hot melt adhesive particles are solid adhesives that are heated above their melting point before being applied to a substrate. According to the desired application, hot melt adhesive has various appearances and textures. They do not require a curing or drying period as they quickly solidify when cooled to the freezing point. Therefore, hot melt […]
EVA hot melt adhesive has long been a favorite adhesive for customers, and there are good reasons for this. The main assets provided by these multifunctional adhesives are: Capable of bonding impermeable surfaces. The ability to fill in gaps. Easy to store. Environmental protection. To make the best use of EVA hot melt adhesive, please […]
For EVA hot melt adhesive used for binding, it can be divided into high-speed adhesive and low-speed adhesive according to different curing times. The curing speed of high-speed adhesive is slightly faster, while the curing speed of low-speed adhesive is slightly slower. According to the material of the book, it is divided into laminated paper […]
