Flexo Printing Explained for Self Adhesive Label Films

Flexo printing uses flexible plates to create high-quality, durable self-adhesive labels. SAILLAGE offers the flexo printing self adhesive label film, which stands out for its print quality and versatility. The table below compares flexo printing to other methods, showing advantages in ink variety, substrate compatibility, and plate durability.

Flexo printing self adhesive label film Process

Flexo Printing Overview

Flexo printing stands as a leading technology for producing high-quality self adhesive label film. This process uses flexible relief plates made from rubber or photopolymer, which transfer ink onto a wide range of substrates. SAILLAGE has advanced this technology by offering flexo printing self adhesive label film solutions that deliver precise ink transfer, vibrant colors, and exceptional durability.

Flexography is a relief printing process that utilizes a flexible rubber or photopolymer plate mounted on a plate cylinder. The printing involves inking the plate image with liquid ink transferred from an anilox roller directly to the substrate using controlled pressure.

Flexographic printing operates on the principle that the image areas on the plate are raised above the non-image areas. Ink is applied to these raised sections, which then press onto the substrate, creating sharp and detailed labels. SAILLAGE’s flexo printing self adhesive label film leverages this principle to produce labels that withstand challenging environments, including moisture, chemicals, and temperature changes.

Flexographic printing on film allows for rapid production speeds and supports up to 8 colors, including spot colors. The process accommodates various ink types, such as water-based and UV-curable inks, enabling custom labels with specific finishes and functionalities. SAILLAGE’s technology ensures that flexo label printing meets the demands of industries like beverages, pharmaceuticals, cosmetics, and packaging.

Key Steps in Flexographic Label Printing

flexo printing self adhesive label film production involves several key steps that guarantee consistent quality and efficiency. The process begins with plate making, where the design is etched onto a flexible plate. Advancements in plate technology, such as flat-top dots, have improved print consistency and detail.

1. The substrate, usually supplied in roll form, enters the flexographic printing press.

2. Ink is applied to an anilox roller, which evenly distributes the correct amount of ink.

3. The inked anilox roller transfers ink onto the flexible plate, etched with the desired design.

4. The plate presses the ink onto the substrate as it passes through the machine.

5. Each color requires its own plate and station, resulting in vibrant and accurate labels.

6. The printed substrate moves through drying or curing systems, such as hot air or UV curing, to ensure proper ink adhesion.

Flexo printing can integrate additional processes, including embossing, laminating, and die-cutting, into a single pass. This integration speeds up production and reduces handling, making flexographic printing on film highly efficient for medium to large volume runs.

· Ink Application: Ink is supplied from an ink pan to the anilox roller.

· Anilox Roller: Distributes a measured amount of ink evenly.

· Printing Plate: Receives ink from the anilox roller.

· Substrate Transfer: The substrate is fed between the printing cylinder and impression cylinder for image transfer.

· Drying/Curing: Systems like hot air or UV curing dry the ink.

Modern flexo printing presses, such as those used by SAILLAGE, operate at high speeds and support advanced ink formulations. Rapid curing under UV light enhances print quality and speeds up production by eliminating drying time. These innovations provide excellent chemical and physical resistance, ensuring that flexo printing self adhesive label film meets industry standards for durability and performance.

Flexographic printing on film often uses eco-friendly acrylic adhesives and facestocks with thermal stability and moisture resistance. SAILLAGE’s flexo printing self adhesive label film supports regulatory compliance for food and pharmaceutical labels, meeting standards such as Regulation (EC) No 1935/2004 and PS 9000. These materials withstand harsh conditions, including low temperatures and exposure to chemicals, making them ideal for beverage, packaging, and cosmetic labels.
