What printing methods can BOPP synthetic paper be used?

BOPP synthetic paper (bidirectional polypropylene synthetic paper) as a special material, has excellent printing adaptability. About the printing methods of BOPP synthetic paper, there are mainly the following:

1. Gravure printing

Features: gravure printing is an indirect printing method, the graphic part of the printing plate is concave, and the blank part remains intact. When printing, the ink is filled to the concave graphic part, and then the ink is scraped off the blank part by the ink scraper, leaving the graphic part of the ink, and finally the graphic part of the ink is transferred to the substrate through the impression cylinder.

Advantages: Gravure printing can print delicate and rich layers of images, bright colors, suitable for printing high-quality packaging materials.

2. Flexographic printing

Features: Flexographic printing using elastic relief plate, through the mesh roller transfer ink to the plate, and then transferred from the plate to the substrate. Flexographic printing has the advantages of low printing pressure, thick ink layer, clear dot and stable printing quality.

Advantages: For materials such as BOPP synthetic paper, flexographic printing can provide good printing results while meeting the needs of mass production.

3. Offset printing (lithography)

Features: offset printing uses the principle of insolubility of oil and water to form the characteristics of oil-wet parts and water-wet blank parts on the printing plate. When printing, the ink is only attached to the graphic part and transferred to the substrate through the rubber blanket.

Applications: Although the application of offset printing on BOPP synthetic paper may be relatively small, but in some specific cases, such as the need for high-precision graphic printing, offset printing is also a viable option.

4. Digital printing

Features: Digital printing is a printing method that transfers graphic information to the substrate without plate making and directly controlled by the computer. It has the advantages of fast printing speed, high flexibility and low cost.

Advantages: For small batch, multi-variety BOPP synthetic paper printing needs, digital printing can provide a fast and efficient solution.

5. Special printing methods

In addition to the above common printing methods, BOPP synthetic paper can also use other special printing methods according to specific needs, such as hot stamping, embossing, UV glazing, etc., to enhance the appearance of the product and added value.

In summary, BOPP synthetic paper can be printed in a variety of ways, including intaglio printing, flexographic printing, offset printing, digital printing and special printing methods. The specific choice of printing method needs to be based on the design needs of the product, production volume and cost considerations and other factors.
