Lamination – process of stamping a special film (sometimes matte, glossy, varies in thickness) on a printed sheet to make it shine, stiffness, for a more reliable protection from external influences. There are several kinds of lamination – hot, cold, etc. The technology of hot lamination is the principle of different temperatures. At temperatures above the melting temperature of the adhesive layer, but below the temperature melting the base material adhesive diffuses into the texture of the paper. The process of thermal diffusion is accompanied by another, and pressure rollers, resulting in a film literally 'grows' into the paper. With cold lamination, when possibility of heating is limited temperature sensitivity laminiruemogo material has limited pressure. Lamination Films is a multi-layer polyester with adhesive layer, known to us as an ordinary plastic container packaging. "Clay" – a combination of multilayer polymer materials with different transition temperature in a plastic condition.

Prior to the laminating film opaque – a whitish color to it gives it the glue. But after exposure to hot rollers laminating polymer acquires transparency and remains so after cooling. Standard lamination film is not intended to outdoor use. The service life of high-quality film – at least two years under normal conditions (temperature 10-20'S, humidity 40-65%). Melting temperature adhesive – 88 C, the basis of the film melts at temperatures above 265 C.

Lamination temperature is chosen depending on the thickness of the film according to the instructions to the laminator. When working with film does not require additional security measures. Standard films are universal, and their application limited additional requirements for laminated products. What are the lamination film? Lamination film (laminate) are divided into two broad categories: Self Adhesive (cold laminate) films and hot lamination. Self-adhesive films are usually more expensive films for hot lamination, but also offer a wide choice of finishes and grades. The choice of laminating films is usually carried out depending on the specific problem – how reliable must be protected and what technology is used. Hot laminating film requires special equipment (rolling laminators, laminating packet), more time to cover the images. But they are more stable and long lived. The most popular are the so-called standard film based on polyester and on the basis of polypropylene. For thin films (40 micron and finer) is technically impossible to use a three-layer structure.

Thin films are mostly used for laminating the lottery products, and therefore are supplied in rolls from 100 to 3000 feet long and from 305 to 2000 mm in width. Thicker polyester film is not so popular ', but demand for laminating wide format, as well as the owners of a batch of office laminators. Significant moment of quality films for laminators is the ratio of the layers, the adhesive and the substrate. The easiest and most efficient working algorithm for choosing the quality of the film: buy the film, in which the foundation layer thicker glue. Than higher this ratio, the better is the film for laminator. In many ways, production quality depends on the compliance level of the laminator to the task. We say, fine, "capricious" film lamination is almost impossible to handle simple office machine – it requires careful tuning.
