Color Penetration

It is easy to occur in NY/PE(CPP) structure. The color of the boiling ring is more red and purple during the cooking process. If the outer layer is changed to PET ring BOPP, then color penetration is easy to occur.

Causes:

Temperature and humidity (water) are the two basic elements that cause color penetration.

● Nylon resin is a thermoplastic polymer from semi-crystalline to amorphous. When the temperature increases, the greater the change of the arrangement between molecules, the greater the possibility of pigment migration.

● The water resistance of nylon is poor, in the process of boiling, water molecules in nylon in and out, washing the pigment components in printing ink.

● Some pigments are water soluble.

Related Suggestions:

✔ Use two liquid type polyurethane ink.

✔  Add additional curing agent for the re-permeable ink.
