Why Hot Melt Adhesive be Preferred in Packaging Markets Today?



It is noticed that more and more industries prefer to use hot melt adhesive for adhesion today. Such as automotive filter, purification filter, bookbinding, product assembly, EPE foam, medical, furniture, non-woven fabric, hygiene products etc. Today we’d like to have a short view on the application of hot melt adhesive in packaging, then you will find the answers by yourself.

What is Hot Melt Adhesive?

HMA ( short for Hot Melt Adhesive) is a thermoplastic polymer based adhesive which is applied in the molten state and which functions primarily by mechanical anchorage.

Benefits of Hot Melt Adhesive:

a) Fast Processing

b) Environmentally Friendly

c) Bond Impervious Surfaces

d) Gap filling

e) Safe

f) Cost effectiveness

g) Efficient shipment and storage

With the above advantages, Hot melt adhesive is used more and more widely instead of water based and solvent based adhesives in many fields.

Hot Melt Adhesive Application in Packaging

HMA is widely used in Case sealing (corrugated and waxed board), Tray forming, Carton sealing (standard bleached, sulfate, fluorocarbon coated, film laminated), Heat seals, Container labeling. Taps. Besides these, HMA is also used in Flexible packaging such as Lid ding, Small container sealing, Induction seal, Wrap around over-wraps and Blister packaging.

How does Hot Melt Adhesive Meet the Typical Requirement for adhesives in Packaging Market?

As we all known, high temperature resistance, very fast set speed, moderate opening time, moderate viscosity, indirect food contact approval is the typical requirement for adhesives in packaging market. With these requirements, there is a trend that, call for the adhesives which have the following features:

Adhesion versatility, increased pot life, lighter color, lower odor, lower application temperature, lower unit cost (increased mileage, lower maintenance).

With the raw material of Polymer, Tackifying Resins, Wax and Antioxidants, HMA is flexible to be adjust to cover all of the above properties and accommodate variety kinds of substrate.
