Introduction of Gravure Printing
Gravure printing, as a printing method with a long history and mature technology, occupies a pivotal position in the printing industry with its unique printing effect and wide range of applications. High-quality graphic printing is realized by transferring ink from the layout to the substrate through gravure.
BOPP (Biaxially Oriented Polypropylene) film, as a premium packaging material, due to its high transparency, high barrier properties and good printing performance.
It is widely used for internal and external packaging of foods such as candies, snacks, and dry goods to ensure the freshness and safety of foods. In addition, BOPP film is also commonly used in the packaging of pharmaceuticals, cosmetics, and electronic products.
Advantages of gravure printing on BOPP filmGravure printing on BOPP films is mainly due to its high print quality, wide range of applications and good abrasion resistance.
First of all, gravure printing can produce thick, vivid and highly saturated color ink layer, making the prints clear and layered, greatly enhancing the aesthetics and attractiveness of the packaging.
Secondly, gravure printing is applicable to various types of BOPP films, including ordinary, heat-sealable, pearlescent, etc., which meets the needs of different packaging fields.
Finally, gravure printing ink has strong adhesion and good abrasion resistance, which enables the printed materials to maintain the integrity and clarity of the pattern in the process of use.
Gravure printing ink selection on BOPP filmThe selection of gravure printing ink is crucial to the printing effect. The ink applied on BOPP film needs to have good adhesion and abrasion resistance to ensure that the pattern is not easy to peel off and wear during the use of printed materials.
Advantages of solvent-based inks for gravure printing: faster drying, suitable for high-speed printing lines. In the printing effect usually has a good gloss and adhesion, suitable for a variety of substrates, including plastic film without special treatment.
Disadvantages: Solvent-based inks contain volatile organic solvents, which can pollute the environment during use and may be hazardous to the health of printing operators. Solvent-based inks are flammable and explosive, increasing the safety risk during the production process.
Advantages of water-based ink in gravure printing: the biggest advantage of water-based ink is its environmental friendliness, so in the process of use can significantly reduce the pollution of the environment, while protecting the health of the printing operator.
Water-based inks are not easily combustible, reducing the risk of fire during the production process.
The initial purchase cost of water-based inks may be slightly higher than that of solvent-based inks, but due to their low ink consumption, high printing efficiency and low long-term environmental impact, water-based inks may be more advantageous in terms of overall cost.
Disadvantages: Water-based inks dry relatively slowly and require a hot air drying device to speed up the drying process.
Some untreated plastic films have a low surface tension and may not be suitable for direct printing with water-based inks. Surface treatment such as corona is needed to improve the surface tension of the substrate before printing.
The development trend of gravure printing applied on BOPP filmWith the continuous development of the packaging industry and the improvement of consumer demand for packaging quality, the application of gravure printing on BOPP film also presents some new development trends.
Technological innovation is one of the key factors to promote the development of gravure printing technology. The application of digital plate making technology makes the plate making process faster, more accurate and environmentally friendly; the development and promotion of environmentally friendly ink meets the market demand for green packaging.
Changes in market demand also guide the development direction of gravure printing technology. Consumers are increasingly concerned about the aesthetics and environmental protection of packaging, prompting printing companies to continuously improve printing quality and production efficiency to meet market demand.
In summary, the application of gravure printing on BOPP film has significant advantages and broad market prospects. Through the implementation of measures such as continuously optimizing the printing process and ink formula, strengthening technological innovation and market expansion, the application effect and market competitiveness of gravure printing on BOPP film can be further improved.
