Hot melt adhesive has gone through several decades of development, has now entered a mature, high-speed development stage, we must be aware of the advantages and disadvantages of the hot melt adhesive before we engag in this industry. Here we are summarizing simply.

Advantages of Hot Melt Adhesives:

1.Reduced waste
2.Rapid setting/bonding action
3.Low cost high volume systems
4.Superior seal quality (penetrates most board stock and secures all flaps)
5.Wide formulation latitude to meet a variety of cost and performance needs
6. Little or no solvent within the adhesive - associated environmental issues avoided
7.Easy dispensing, simple to automate, dispensing equipment not complex or expensive
8.Tamper evident packaging (hot melt seal will cause package board fiber to tear when opened)
9.Pilferage resistant (unlike tape, hot melt adhesive seals cannot be opened and resealed without the consumer's knowledge.)

Disadvantages of Hot Melt Adhesives:

1.Can be susceptible to creep under load
2.Potential to have poor wetting properties
3.Some hot melt adhesives are susceptible to solvent attack
4.Heat required to melt adhesive unsuitable for delicate applications
5.Limited adhesion strength when compared with epoxy, acrylics, polyurethanes, etc.
