Lamination is one of the fundamental methods of print finishing, protecting prints from mechanical damage, moisture, and UV radiation. There are two primary lamination techniques: hot and cold lamination. This article focuses on cold lamination, which is gaining increasing popularity in the printing industry.
What is Cold Lamination?
Cold lamination is the process of coating the surface of a print with a protective film that does not require high temperatures, only mild heating to 40°C to ensure better adhesion to the material. Unlike hot lamination, this method relies on pressure-activated adhesive. This makes it safe for prints sensitive to high temperatures, such as those produced with water-based inks or large-format prints.
Advantages of Cold Lamination
This method offers numerous benefits, making it an attractive option for printing houses and companies producing advertising materials. Firstly, cold lamination allows for the protection of even delicate surfaces without the risk of damage. Secondly, the films used in this process are available in various finishes – matte, glossy, or textured – enabling striking visual effects. Additionally, cold lamination provides high resistance to weather conditions and mechanical damage, making it an ideal solution for materials displayed outdoors.
Applications of Cold Lamination
This technique is widely used in the printing and advertising industries. It is employed to protect posters, banners, maps, stickers, and POS materials. It is also highly effective in the production of labels, catalogue cards, and other items requiring durable protection. Furthermore, the method is used in industrial production to apply mounting adhesive in the form of double-sided tapes.
How Does the Cold Lamination Process Work?
The cold lamination process is relatively straightforward and does not require high temperatures. The print is placed on a substrate, and then, using a laminator, the film is pressed onto its surface. Thanks to the special adhesive, the film adheres tightly to the print, creating a durable protective layer. Manual film application methods are also available for short-run production.
Summary
Cold lamination is an effective method for protecting and enhancing prints without the need for high temperatures. It is an excellent solution for companies seeking durable and aesthetically pleasing protection for their printed materials.
