I have printed StoraEnso for liquid packaging cartons and the curing methods we used were UV and EB (Electron Beam) inks.
At that time we made sure we had good climate and humidity control of the Paper Board prior to printing and monitored our fountain solution very closely as we found this could effect the curing of our inks. Also we made sure our inks were not putting down a too thick of an ink film on the board.

The problem with our machine is that we don't have uv

You must use an ink set made for PE. We make cups every day on double side PE. No UV. Just conventional inks made for PE coated board and several different board types including Stora board.

Hi,
What inks do you use ?

1. Correct. These inks are classified as "foil inks" (for printing on partially absorbent materials). Ask your local supplier for inks with this specification. Remember, they must be food-grade.

2. It's also a good idea to find a paint series with below-average paint transfer, approximately 0.9-1.0 grams per square meter. This way, you can achieve fairly rich spot color with a moderate application of paint.

3. Without water-based varnish, it's more difficult, but if possible, use a food-grade oil-based protective varnish from the printing unit. It's essentially the same paint, but it will provide an additional protective layer against abrasion.
