Hot melt adhesive (Hot Glue) is a kind of plastic adhesive. Its physical state changes with temperature within a certain temperature range, while its chemical properties remain unchanged. It is non-toxic and tasteless, and is an environmentally friendly chemical product.
Because the product itself is solid, it is easy to package, transport, store, solvent-free, pollution-free, non-toxic; and the production process is simple, high value-added, high bonding strength, fast speed and other advantages.
