Hot melt adhesive suppliers produce bonding glue that is activated by the application of heat and pressure. Invented in the late 19th century, Hot Melt adhesives are thermoplastic polymers that are economical and available in a wide variety of formats including, chips, pellets, blocks or cylindrical sticks. Hot melts can be applied via hot melt tanks or glue guns.
In the corrugated converting industry, hot melt adhesives are used in tray forming, case and carton sealing and can be used on many types of paper including coated stock. Resistant to moisture and water, hot melt adhesive is a safe and effective adhesive for food packaging and can withstand rigorous handling.
We offer hot melt adhesive in a wide variety of set speeds, open time, application temperatures, viscosities and strength.
Adhesive compounds must be stable when heat is applied and not breakdown after the “curing” process is completed. They must have good cold weather performance and not become brittle when exposed to extreme cold temperatures. Additives such as pigments, UV stabilizers, and biocides can be added.
Advantages Over Solvent Based Adhesives
- No volatile organic compounds.
- Eliminates the drying / curing step.
- Long shelf life (3+years).
- Environmental friendly due to ability to easily dispose the substance without special precautions.
- Easy shipping due to solid state that does not attach to the container prematurely.
Disadvantages of the Product
- Limited to using substrates that are not sensitive to higher temperatures.
- Loss of bond strength at higher temperatures.
- Necessity to reduce stress to the bonding by adding additional curing steps such as moisture or Ultraviolet rays.
Conclusion:
The American Corrugated Industry Gains Competitive Advantage:
Hot melt adhesive suppliers have refined this adhesive to be used with a wide variety of substrates while achieving quick set times with a strong bond; faster productions speeds with minimal waste are the result.
