How to do extrusion coating, when corona does not provide enough bonding strength

Extrusion coating, when corona does not provide enough bonding strength.

Our suggestion: FLAIR ®, because it leads to higher surface tension and to higher adhesion.

FLAIR® has proved before that it can reach extremely high surface energy levels, up to 73 mN/m are possible in principle. Above that adhesion properties are excellent much better than corona even for the same dyne level. Foil treated with FLAIR® has shown condition under which e.g metal adhesion was up to three times better than with standard metallized films.

And most importantly no ozone treatment is necessary!
