The Hot Melt Lamination Process

The hot melt lamination process, unlike flame, doesn’t rely on the material itself to act as an adhesive.

Instead, a separate adhesive substance is heated up before being evenly distributed by rollers across the material. Finally, the process is completed in a similar method to flame lamination by feeding the materials through a compression roller to bond together.

What is Hot Melt Lamination?

This lamination uses a polyurethane adhesive applied to one surface with a hot roller in order to bond it to another.  The adhesive can be applied as either a continuous layer or in a dot pattern. Hot melt lamination is useful for binding the same material or two different types.

What is Hot Melt Adhesive used for?

Hot melt industrial glue can be used in all types of product assembly, such as small joint assembly, large surface lamination, mounting, and trip attachment. Product assembly that involves hot melt applications can include appliances, mattresses, HVAC, and many others.

What is Polyurethane Hot Melt Adhesives?

Polyurethane hot melt, more commonly known as PUR hot melt, is an adhesive that is heated and dispensed from a cartridge or slug, unlike traditional hot melt which is usually in the “stick” or “pellet form”. Polyurethane (PUR) hot melt has a unique process, as it solidifies through moisture in the air to form and create a super-strong bond that won't re-melt.

Where is PUR Hot Melt Adhesive Used

Polyurethane (PUR) hot melt is used widely in manufacturing and product assembly applications and has grown in popularity every year. Normally PUR Adhesives in applications are required to have strong bonds to plastics, wood, fabrics, leather and many more materials.

One of the main reasons they have become increasingly popular is due-to how versatile they are. PUR can be applied as a bead or sprayed to cover huge surface areas. These adhesives also have a wide range of open times and viscosities, allowing them to cater to specific application needs.

Because of its durability, strength, and quick set time, (PUR) is ideal for a variety of industries which involve:

  • Construction
  • Woodworking
  • Ceramic ceiling tiles
  • Furniture Repair
  • Laminate countertops
  • Finish carpentry
  • Broken glassware repair

What is the Difference Between PUR Hot Melt and Regular Hot Melt?

Traditional Hot Melt Bonds

One of the biggest differences between PUR hot melt and traditional hot melt is the type of bond they create. A traditional hot melt bond can be seen as a wax bond. When you heat it up, it’ll become a liquid, then apply it a stick your two parts together. However, if you were to heat the parts back up, the hot melt would become a liquid again, and you could easily take the substrates apart.

Polyurethane (PUR) Hot Melt Bonds

PUR hot melt is very different to traditional hot melt. It is dispensing in very much the same way, though the adhesive is heated to a liquid state, applied to your material and then “stuck” together. This is what makes PUR hot melt unique. As it begins to cool, the hot melt reacts with the moisture within the air and changes chemically to create an incredibly strong bond. This bond then continues to get stronger over 24-48 hours until it is fully cured and super strong.

Hot Melt Lamination FAQs

The use of PUR hot melt adhesives provides a wide range of gluing options for different materials such as paper, foils, and laminates. The surface results range from high gloss to super matt.

Hot melt adhesive lamination, in comparison to flame lamination, allows to bond fabric, without the use of foam as an adhesive.

The primary polymers used in hot melts are ethylene-vinyl acetate (EVA), polyolefins, polyamides and polyesters, styrene block copolymers, polyethylene, and ethylene-methyl acrylate (EMA) or ethylene n-butyl acrylate (EnBA).

Polyurethane Hot Melt is more commonly known as PUR Hot Melt. It is an adhesive, which is heated and distributed from a cartridge or slug, unlike the conventional hot melt that is in a pellet or stick form. PUR Hot Melt is distinctive because it hardens through moisture in the air, to form a super strong bond that cannot re-melt.

Polyurethan Hot Melt provides a stronger bond, than conventional hot melts. This is due to the PUR Hot Melt forming a strong intimal bond, which continues to strengthen because of how the adhesive reacts with moisture in the air.

This chemical process is also known as cross-linking. This means the PUR Hot Melt attaches to the object being glued and itself to form a stronger, permanent bond.


Hot melts are applied to a material in the liquid (molten) state. The time between applying the adhesive and then bringing the second material in contact is called open time. When the second material is brought into contact, the adhesive cools down and solidifies very quickly.
