Playing Cards Durability Issue

Recommended Posts

Hello Friends

How are you doing?

I manufacture Playing Cards

On both Paper and Plastic


I need help as I am receiving a lot of complaints regarding durability in my Plastic Playing cards

We print on Rigid PVC one side is matt[ smooth side] and other side is grain [ rough side]

The complaints i receive is that the ink wears off after 1 day usage

to protect the ink we use Water based Coating

we do not know much about the science involved but over here



The issue i feel is adhesion of the inks with the substrate,

If someone here can help me out with information on how to improve my durability It will be of a Huge help

Thanks
Raahul Singh

Would it be better to laminate with a thin, plastic film? Do you apply the coating to a whole sheet of cards before cutting them out or are the cards cut out before you coat them?

 

Going with your suspicions on the cause, this pdf article mentions something about surface energy being too low in many plastics and the need for pretreatment to increase it to improve the wetting characteristics:
