Process & troubleshooting
Setting temperature, speed and nip pressure on a hot roller laminator
A starting point for the main film families, and how to adjust one variable at a time when the bond is not forming.

A starting table
Standard BOPP runs around 95 °C at 30 m/min on 300 gsm board. PET needs about 5 °C more. Digital grades sit near 85 °C. Soft touch sits between standard and digital because of the thicker coating.
Change one variable per trial
Temperature first, because it decides whether the adhesive flows at all. Then speed, which decides how long the sheet stays in the nip. Pressure last, because excess pressure hides a temperature problem rather than solving it.
What a good bond looks like
Peel a cooled sample from the trim edge. A correct bond pulls paper fibre with it. A bond that releases cleanly with no fibre has not formed, regardless of how good the surface looks.
Before you commit a roll
Trial on your own board at production speed. Send the substrate, ink coverage and machine model and we will confirm a starting grade and temperature.

BOPP vs PET lamination film: how to choose by substrate and fold
The two base films look similar on a sample table and behave differently on press. A practical comparison of stiffness, elongation, heat response and cost per sheet.

Gloss or matt: what the surface does to print, light and handling
Gloss raises colour saturation and reflection; matt lowers both. The choice changes how a carton reads on shelf and how it ages in the hand.

Velvet surfaces are judged by hand, so small process errors show. Temperature, nip pressure and post-press decoration each change the final feel.
