Hot melt adhesive is a kind of plastic adhesive. Its physical state changes with the change of temperature within a certain temperature range, but 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, and non-toxic; as well as the advantages of simple production process, high added value, high bonding strength and fast speed.
The advantages of hot melt adhesives in a wide range of industries:
1. Fast curing speed, good bonding strength and flexibility. Hot melt adhesives can be cured and bonded within a few tenths of a second to a few seconds, and have the characteristics of melting when heated and sticking when cooled. This enables packers to use hot melt adhesives to use higher speed production lines and increase production while reducing rejects.
2. Hot melt adhesive does not contain water and any other solvents. Its solid can be made into blocks, strips, granules or films, which are easy to transport and store. It has a long service life and eliminates damage and waste, making it easy to use.
3. Wide range of bonding objects, both bonding and sealing, no drying process is required, the bonding process is simple, and the economic effect is good.
4. The hot melt adhesive has good gloss and gloss retention, and excellent shielding properties.
The advantages of hot melt adhesive in the carton industry application:
1. Seal the box with hot melt adhesive, which is suitable for high-speed, high-automation modern production.
2. Compared with the traditional sealing belt sealing, the cost is reduced.
3. It cannot be recovered after unpacking, which is suitable for the disposable and safety of product packaging.
4. High bonding strength, so that the carton is not easily deformed and cracked.
5. Using the fluidity of hot melt adhesive, the sealing effect of the carton can be achieved.
