Carbon black pigment paste is a key component in flexographic printing ink, mainly used to provide high-strength black coloring effect.

The following is an introduction to its core features and main uses:

Characteristics of charcoal black paste

1. High coloring power and blackness

Carbon black has extremely strong hiding power and color development strength. Adding a small amount can achieve deep and saturated black, making it suitable for printed materials that require high contrast.

2. Excellent dispersion stability

Professional charcoal black paste undergoes fine grinding and surface treatment, which can maintain uniform dispersion in water-based or solvent based flexographic ink systems, reduce precipitation and agglomeration, and ensure stable printing process.

3. Environmental compatibility

Flexographic printing often uses water-based ink to meet environmental requirements. Modern charcoal black paste is typically designed as a low VOC, heavy metal free formula that meets strict safety standards in industries such as food packaging and toys (such as FDA, REACH).

4. Optimization of rheological properties

The viscosity and flowability of charcoal black paste have been adjusted to match well with the flexographic ink system, ensuring smooth transfer during printing, clear dots, and avoiding ink flying or plate blocking.

5. Excellent patience performance
It has good light resistance, heat resistance, and chemical resistance, and printed materials are not easily faded when exposed to light or humid environments for a long time. It is suitable for fields with high durability requirements such as outdoor labels and packaging.

Main purpose

1. Food and daily chemical packaging

Used for printing on plastic bags, paper boxes, flexible packaging, etc., in compliance with safety regulations for food contact materials, and black text or patterns can enhance product recognition.

2. Label and Adhesive Printing
In the printing of product labels, barcodes, shelf life and other information, charcoal black paste can achieve high-definition text and fine lines, ensuring scanning recognition rate.

3. Film and flexible material printing
Suitable for printing plastic films such as PE, PP, BOPP, as well as paper, corrugated paper and other materials, with strong adhesion and fast drying speed.

4. Special printing field
Such as conductive ink (adding conductive carbon black for anti-static packaging), anti-counterfeiting ink, etc., which utilize the conductive or light absorbing properties of carbon black to achieve special functions.
