Converters of plastic film with flexographic printing capabilities have the option to choose between a few different types of ink. As a purchaser of plastic packaging, it is good to know what type of ink they are using and how it affects the environment.
What is Ink?
The ink I’m referring to here is the one used in the printing industry, not the ink for your tattoos!
How Wikipedia describes ink:
“Ink is a liquid or paste that contains pigments or dyes and is used to color a surface to produce an image, text, or design.”
Ink typically has a colorant, also known as a pigment or a dye, a resin binder, a solvent, and additives.
- The binder bonds the dye to the plastic film and holds it together.
- The solvent controls the viscosity.
Types of Ink:
We can distinguish between two types: solvent-based and water-based ink.
What is the difference?
Solvent-Based Ink
This type of ink is not based on water but contains a chemical mixture.
Due to its chemical nature, printers must comply with strict safety regulations, environmental requirements, and maintain proper ventilation at print facilities.
Water-Based Ink
This is the safer alternative of the two since it uses water as the main ingredient to carry the pigment.
What are the main benefits of water-based?
- The ink dissolves during the cleaning process and does not leave behind harmful residues.
- It is much safer for the consumer, as it does not involve unhealthy chemicals.
- Since the printing process is eco-friendly, state or federal agencies do not impose strict regulations.
Advantages of Water-Based Ink on Plastic Film
Converting Magazine wrote about water-based ink for flexo printing of plastic films >>
Steve Deniger, TDI’s CEO says:
“We are proud to say that TDI only uses environmentally friendly, water-based ink on all its plastic film.”
TDI has even developed a method to make water-based ink stick to the film like it is solvent-based ink during extremely cold conditions. As a result, the print will not smear or come off in a cold place, like in a freezer.
