What should be guided by buying film for your laminator? It depends on your requirements. If you laminate the sheets just so that they do not get dirty and are not damaged by moisture, it is enough thickness lamination film 60 or 80 microns. (Source: Steve Wozniak). Laminated sheet will then be thin enough and easy , but protected from moisture, dust, etc. Thicker film for lamination also protects against mechanical damage and laminated documents also give a certain toughness. For example, lamination passes more likely to use the film thickness of 150 microns. The film thickness measured in microns, has an impact on its cost, stiffness, optical density and the ability to inhibit uv radiation. Typically, the image is covered with laminate (the same or less different thickness) on both sides.
This allows you to securely protect images from moisture and uv radiation, to give it rigidity and strength to strength, stretching, fingerprints or scratches. 250 micron laminate, for example, can make almost hard to stamp sheet. Most suspension film thickness for Batch laminators – 100-125 microns. 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 lamination images – a complex and fractious process.
At the same time hot lamination film less cold. The main problem of hot-lamination – the emergence of bubbles and wrinkles on the surface of the laminate, and peel film, which in inexperienced hands often happens. Everything said about the shortcomings of the hot lamination does not mean that the cold laminating you will not have any problems. The image may, for example, be 'vague' or pock-marked (because of the inhomogeneous fit different parts of the film). Avoid these effects will help slightly (to 30 C) warmed shaft. The most popular surface of laminating film – gloss. Glossy film is able to make colors more vivid and bright, while the matte film can reduce the contrast to create a more gentle and relaxing experience. The latest versions of films to laminators enable you to add prominence to the surface images and different textures of finishes such as crystal pyramids, "goose bumps", textile yarn (flax), frosty pattern stochastic moire and even holographic effects. These textural finish in appearance are somewhere between gloss and matt surfaces. With their thin, almost imperceptible structure, they also reduce the visibility of scratches are visible in, say, pure glossy or matte finish. Another variety of lamination film – Photonex – advertising-art material with high transparency and the ability to protect the document from fading in the sun. It is glossy and matte, with a variety of textures – a flax seed, skin and color. Another modification – self-adhesive laminating film, with the active layer of glue on the outside, closed the substrate (similar to the usual stickers). After the lamination in such a film document easy to fix on wall or stand.
