OA2 can be used for producing flexible packaging printing within 3 colors (including 3 colors), sealing width ≤ 1cm and without requirement for printing registration, such as blank bag, vacuum freeze bag, aquatic product bag, and vacuum compression bag. The specific applications as below, inner bag for nuts (walnuts, sunflower seeds, etc.) and inner bag for meat products (Texas grilled chicken, steak, etc.), electronic shielding packaging, liquid packaging, such as wine, beverage, sauce, breast milk storage bag, water storage bag, ginseng chicken soup, oil bag, box bag, aerospace food, live fish bag, cold and fresh meat, seafood, halogen lock fresh packaging, etc.
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.
