Manufacturing Techniques

The manufacturing techniques we can deploy include knife- or roll-over-roll, reverse roll, gravure, Meyer bar, through method, calendaring and extrusion or slot die. These are used as follows:

Knife or roll-over-roll:


The most common coating technique, either direct onto the carrier or onto a paper or filmic liner.

Gravure, Meyer Bar:


Often used for coating release or primer in low viscosity systems, and for patterned adhesives.

Calendaring and Extrusion:


Used for solventless adhesive (RR, HCM) where there is a need to melt the adhesive.

Reverse Roll:


Preferred for coating where the adhesive could go through the carrier, eg cloth.

Through Method:


Double-sided tape in one pass with same adhesive on both sides.

Slot Die:


A relatively new method for solvent-based or water-based adhesive, which offers better coat weight control and lower coat weights.
