Case Study | Formulation Design and Application of Water-Based Plastic-Replacing Oil
What is water-based plastic-replaceable oil?
Water-based plastic-replacing oil replaces films prepared by lamination processes. It mainly consists of water-based matte polyurethane, water-based glossy polyurethane, transfer agents, environmentally friendly solvents, additives, deionized water, and other components; By transferring water-based plasticizer oil onto substrates using offset or gravure printing, the paper has a simple, elegant, rustic, and three-dimensional style that blends seamlessly with the substrate.
The coating features scratch and wear resistance, fold resistance, explosion-proof protection, a smooth hand feel, and suitable post-processing properties. It meets requirements for energy conservation, emission reduction, and plasticization reduction, and environmental protection. It is widely used in shoe boxes, cosmetic boxes, and outer packaging consumables.
As an environmentally friendly coating, water-based plastic-replacer oil is gradually becoming the new favorite in the packaging and printing industries.
Common paper coating techniques
Does the plastic replacement oil process have to have one base and one side? In fact, considering cost, the plastic replacement oil process usually requires one base and one side. Many customers require the oil to have good adhesion to the ink, wear resistance, bend resistance, explosion-proof color, scratch resistance, matte finish, and also serve to protect the ink
If the scratch-resistant matte oil does not adhere well to the ink, then you need to apply a primer with good adhesion to the ink first, followed by a scratch-resistant matte coat.

Formulation application scenarios
Printing processes and equipment
Currently, there are two printing methods for paper plastic replacement oil: one is the online inline method, and the other is the offline inline method.
Online Connection Method—an integrated process for ink printing and plastic oil replacement printing
Offline inline method—the process of replacing ink with plastic oil on the printed paper
