Overview of Application Fields and Materials of Ink

1、 Paper products

Paper products are one of the most widely used materials for ink applications. Whether it is ordinary office paper, printing paper, or special copperplate paper, thermosensitive paper, grazin paper, release paper, and corrugated cardboard, ink can be used for printing. Ink can firmly adhere to the surface of paper, providing clear and long-lasting printing effects.

2、 Plastic materials

Plastic weaving: Ink is also widely used in products such as plastic woven bags. Due to its unique surface properties, this material requires the selection of matching ink to ensure stable printing effects and adhesion.

Plastic film category: PE film, BOPP film, PET film and other plastic films are also important application areas for ink. With the advancement of technology and the maturity of auxiliary methods such as corona discharge, the application of environmentally friendly inks such as water-based inks on plastic films is becoming increasingly widespread.

3、 Non traditional materials

Metal and glass: For materials such as metal and glass that do not have absorption properties on their surfaces, it is usually necessary to use two-component ink or other special inks to achieve good printing results. These inks can form a strong ink layer, ensuring the durability of patterns and text on metal and glass surfaces.

Nylon cloth, leather, etc.: Special inks such as nylon ink have been widely used in the fields of shoe making, luggage making, umbrella making, etc. They can firmly adhere to materials such as nylon cloth, waterproof cloth, PU/PVC artificial leather, providing long-lasting printing effects.

4、 Special material requirements

Medical packaging: Medical packaging ink needs to have characteristics such as being not easy to peel off, non-toxic and harmless, and good adhesion. This type of ink typically uses active ink as the main component to ensure safety and stability in pharmaceutical packaging.

Food packaging: Food packaging ink requires environmental protection, non toxicity, and does not affect the quality of food. Therefore, environmentally friendly inks such as water-based inks have been widely used in the field of food packaging.

Electronic devices: Electronic device ink is generally UV cured ink, which has the characteristics of short drying time, good light resistance, and wide printability. They are widely used in printing high-precision patterns and text for electronic products.

5、 Ink selection and material matching

In practical applications, selecting the appropriate ink and material matching is the key to ensuring printing effectiveness. Different materials have different surface properties, absorbency, and chemical stability, so it is necessary to choose the ink type that matches them. For example, when printing on plastic films, environmentally friendly inks such as water-based ink or UV ink can be chosen; When printing on metal and glass, it is necessary to choose two-component ink or other special inks to ensure the printing effect.

In short, ink has a wide range of applications in various fields and materials. With the continuous advancement of technology and the improvement of environmental protection requirements, the types and performance of inks are also constantly updated and optimized. When choosing ink, it is necessary to comprehensively consider factors such as material, printing process, and environmental requirements to ensure stable and long-lasting printing effects.
