Characteristics of BOPP flexible water-based ink
Date: Aug 31 2023 From: Star Color
BOPP (Biaxially Oriented Polypropylene) is a widely used material in the flexible packaging industry due to its excellent properties such as high tensile strength, clarity, moisture barrier, and printability. Flexographic printing is a popular method for printing on BOPP films and other flexible substrates.
BOPP flexographic printing ink is specially formulated to adhere to BOPP films and provide high-quality, durable prints. These inks are designed to work with the flexographic printing process, which involves using flexible relief plates to transfer ink onto the substrate.
Key characteristics of BOPP flexographic printing ink include:
1.Adhesion: BOPP inks have good adhesion to the BOPP film's surface to ensure the print remains intact even after various handling and packaging processes.
2.Fast Drying: These inks dry quickly on the BOPP surface to prevent smudging and enable fast production speeds.
3.High Pigment Load: BOPP inks typically contain a high concentration of pigments to achieve vibrant and vivid colors on the transparent or semi-transparent BOPP film.
4.Good Opacity: Since BOPP films are transparent, the inks are formulated to provide good opacity to cover the underlying layers and maintain color fidelity.
5.Resistance: The inks are often designed to resist abrasion, scratching, and chemicals, ensuring the printed content remains intact throughout the product's lifecycle.
6.Compatibility: BOPP flexographic inks should be compatible with the flexographic printing process, which involves using anilox rollers to transfer the ink to the printing plates and subsequently onto the substrate.
It's important to note that the specific formulation of BOPP flexographic inks may vary depending on the manufacturer and the printing requirements. Different printing applications, such as surface printing or reverse printing (printing on the backside of the film), may also require different ink properties.
When using BOPP flexographic inks, it is essential to follow the manufacturer's guidelines and best practices for ink storage, handling, and printing parameters to achieve the desired print quality and performance. Additionally, it's crucial to ensure that the ink is compatible with the printing press and the BOPP film to avoid any potential issues during the printing process.
