Overlamination films are an essential component in the construction of pressure-sensitive labels, providing a range of benefits that enhance both the aesthetic appeal and functional performance of labels. These films are applied over the printed surface of a label, serving multiple purposes such as protection against environmental elements, enhancement of visual appeal, and improvement of durability.
Key Functions of Overlamination Films
- Protection of the Printed Surface: Overlamination films protect the printed surface from color deterioration, maintaining the label’s quality and appearance. They act as a barrier against scratches, abrasion, and chemical damage, which is crucial for labels that undergo rough handling or are exposed to harsh conditions .
- Preventing Color Loss Due to UV Light: Many overlamination films are designed with UV-resistant properties, ensuring that the labels remain vibrant and legible even after prolonged outdoor exposure. This is particularly important for labels that are used in environments with intense sunlight or under UV light sources .
- Ability to Print After Over-lamination: Some overlamination films allow for post-lamination printing, which can be beneficial for applications requiring variable information printing after the initial label production. This feature enables the incorporation of barcodes, QR codes, or other variable data with high durability and clarity .
- Aesthetic Enhancements: Overlamination films can add a glossy or matte finish to the label, enhancing its visual appeal. They can also provide a range of special effects, such as soft-touch or holographic finishes, to differentiate the product and attract consumer attention .
- Environmental Protection: Overlamination films can provide water resistance, making the labels suitable for use on products that come into contact with water or are used in humid environments.
Market Trends and Applications
The market for overlamination films is driven by the need for high-quality, durable labels in various industries, including pharmaceuticals, cosmetics, food and beverage, and industrial equipment. The growth of digital and hybrid printing technologies has also influenced the development of overlamination films, demanding materials that can keep pace with these advanced printing methods .
In recent years, there has been a trend towards commoditization of overlaminates, with a flood of imported commodity products driving prices down. However, there is also a growing demand for high-performance overlaminates that can meet the sophisticated requirements of innovative printers and end users .
Anti-counterfeiting measures are another area where overlamination films play a crucial role. They can incorporate security features that are transparent to the press operator, providing an additional layer of protection against counterfeiting without compromising the label’s production process
