How does gravure water-based ink for flower paper packaging adhere to flower paper packaging materials?
Release Time : 2025-02-17
The adhesion of gravure water-based ink for flower paper packaging to flower paper packaging materials usually shows good performance, but the specific adhesion level is affected by many factors.
1. Basic situation of adhesion
The adhesion between gravure water-based ink and flower paper packaging materials is one of the key factors in printing quality. Good adhesion means that the ink can be firmly attached to the surface of the substrate and is not easy to fall off or crack, thus ensuring the durability and beauty of the printed product.
2. Factors affecting adhesion
Ink composition: The resin, pigment, additives and other ingredients in water-based ink have an important influence on its adhesion. The selection and ratio of resins, the dispersibility of pigments, and the type and amount of additives will affect the interaction between ink and substrate.
Substrate properties: The surface energy, roughness, ink absorption and other characteristics of flower paper packaging materials have a direct impact on the adhesion of ink. Generally, materials with higher surface energy are more likely to form a strong bond with ink.
Printing process: Process parameters such as printing pressure, speed, and drying temperature will also affect the adhesion of the ink. Appropriate printing pressure helps the ink to penetrate and adhere to the surface of the substrate better; while the drying temperature will affect the curing speed and degree of the ink, thereby affecting the adhesion.
Environmental conditions: Environmental conditions such as temperature and humidity in the printing workshop will also affect the adhesion of the ink. Excessive humidity may cause poor drying of the ink, thereby affecting the adhesion; while excessive temperature may cause the ink to dry excessively, resulting in cracking or shedding.
3. Methods to improve adhesion
Optimize ink formula: By adjusting the proportion and type of components such as resins, pigments, and additives in the ink, the adhesion performance of the ink can be improved. For example, choose a resin with higher adhesion, use a pigment with better dispersibility, etc.
Surface treatment of substrates: Surface treatment of the substrate before printing, such as corona treatment, grinding, or primer coating, can increase its surface energy and roughness, thereby enhancing the adhesion of the ink.
Adjust printing process parameters: According to the characteristics of substrates and inks, appropriately adjust process parameters such as printing pressure, speed and drying temperature to obtain the best adhesion effect.
Control environmental conditions: Maintaining suitable temperature and humidity conditions in the printing workshop is conducive to the normal drying and curing of inks, thereby improving adhesion.
In summary, gravure water-based ink for flower paper packaging usually shows good adhesion to flower paper packaging materials. However, in order to obtain the best adhesion effect, it is necessary to comprehensively consider multiple factors such as ink composition, substrate properties, printing process and environmental conditions, and take corresponding measures to optimize and adjust. Through reasonable formula design, substrate surface treatment, printing process parameter adjustment and environmental conditions control, the adhesion level of gravure water-based ink on flower paper packaging materials can be significantly improved.
