PU Resin for Ink
The liquid flexible packaging ink is made by resin, pigment, additives and solvent. And the PU resin for ink (also called ink binder)is the core of the ink, due to the PU advantage, now PU resin for ink (ink binder) becomes more and more popular, especially for the retorting application. We have the plasticizer, semi-film-former and film-former PU resin for gravure ink. These polyurethane ink binders are widely used for surface printing ink and lamination ink in both flexo and gravure printing technology. With the excellent color strength and adhesion property, they can meet different requirements and applications. All our products are TOL & MEK free, and our product safety expert assures our polyurethane resin for inks can meet the regulation and law around the world, including Nestlé Guidance Note, EuPia Guidline, Swiss Ordinance, also FDA, EU10/2011 and China GB9685-2016.
PU Resin for Ink Types
PLASTICIZER TYPE PU RESIN
The plasticizer grade PU resin for ink (ink binder) is mainly for the surface printing ink, which cooperates with NC resin. Because it is polymeric plasticizer, there is no migration issue, and it has good heat, oil, fat,...
SEMI FILM FORMING TYPE PU RESIN
The semi-film-former grade PU resin for ink ( ink binder) is widely used for surface printing ink and simple lamination ink, which cooperates with NC resin. This polyurethane resin for inks is based on the plasticizer grade PU resin, but we increase th...
FILM FORMING TYPE PU RESIN
The film-former grade PU resin for ink ( ink binder) is mainly used for lamination ink, some also can make the surface printing ink due to excellent color strength. Normally it can cooperate with NC resin, vinyl resin (Vin...
What Are The Uses Of Polyurethane Resins for Inks?
Polyurethane resins for inks ( ink binder ) are versatile polymers used in a wide range of applications, including the formulation of inks. Their unique properties make them particularly suitable for various types of inks used in printing processes. Here are some of the primary uses and benefits of polyurethane resins for inks:
Flexibility and Durability: Polyurethane resins for inks impart excellent flexibility and durability to inks, making them ideal for use on substrates that undergo bending, stretching, or other forms of deformation.
Adhesion: One of the key advantages of polyurethane PU resins for ink is their ability to adhere well to a wide range of substrates, including plastics, metals, and paper. This makes them suitable for various printing applications where strong adhesion is required to ensure the longevity and quality of the print.
Chemical and Abrasion Resistance: Inks formulated with polyurethane PU resins for ink exhibit excellent resistance to chemicals, solvents, and abrasion.
Gloss and Appearance: Polyurethane resins for inks can enhance the gloss and overall appearance of printed materials.
Flexographic and Gravure Inks: Polyurethane resins for inks are particularly useful in the formulation of flexographic and gravure inks.
Waterborne and UV-Curable Inks: The push towards more environmentally friendly printing processes has led to the development of waterborne and UV-curable inks containing polyurethane resins.
PU Resin for Ink FAQs
Q
Why is PU resin used in ink formulations?
A
PU resin is used in ink formulations because of its ability to improve the ink’s performance on various fronts. It enhances the ink’s flexibility, making it suitable for printing on substrates that may bend or stretch. The PU resin for ink （ink binder）also improves adhesion, ensuring that the ink sticks well to different materials, including plastics, metals, and paper. Additionally, PU resin contributes to the ink’s resistance to chemicals, solvents, and physical wear, and can be formulated to provide a desired gloss or matte finish.
Q
Are PU resins environmentally friendly?
A
The environmental friendliness of PU resins for ink depends on their formulation and the application in which they are used. Waterborne PU resins for ink and those used in UV-curable inks are considered more environmentally friendly options compared to traditional solvent-based systems. They emit lower levels of volatile organic compounds (VOCs), reducing their impact on air quality. However, the production and disposal of PU polyurethane resins for inks still pose environmental challenges that are being addressed through ongoing research and development.
Q
How do PU resins compare to other resins used in inks?
A
PU resins for ink offer several advantages over other types of resins used in inks, such as acrylics, vinyl, and alkyds. They generally provide superior flexibility, adhesion, and resistance to chemicals and abrasion. PU resins for ink can also be formulated to achieve a wide range of finishes, from high gloss to matte. However, the choice of polyurethane resin for inks depends on the specific requirements of the printing application, including the substrate, printing process, desired properties of the final print, and environmental considerations.
Q
Can PU resin inks be used in digital printing?
A
Yes, PU resin inks can be used in digital printing, particularly in applications where durability, flexibility, and adhesion are important. They are suitable for printing on a variety of substrates, including flexible films and rigid materials. The use of PU resins for digital ink formulations allows for high-quality prints that can withstand handling, exposure to elements, and mechanical stress.
