Our laboratory tested the Origami facial milk packaging with a RT-01 rub tester from Labthink
with the following parameters:
Speed: 42 cpm
Weight: 4 lb (1,8144 kg)
Strokes: 500
With these heavy weight the rub reistance is only good after a extra drying of the samples in the oven
for 30 min at 125°C.
That means, the ink was still not dry or good absorbed well in the cardboard when the samples arrived in Germany.
If possible they should think about the reduction of ink density,other ink type, maybe other cardboard. And they should use
more coating for protection (anilox roller with a higher volume).
Because you told me already that they used a 100 l/cm² (10-11 bcm) roller.
