Lamination of printed products and bears an aesthetic and practical function. In addition to a significant improvement in the appearance of the printed objects (posters, photos, business cards, documents, packaging, covers, calendars, brochures, etc.) of the coating film protects the materials from external influence destructive factors (water, mechanical damage, dust, sand etc.), considerably extending their service life. Efficiency and profitability of the method has prompted many institutions to buy a laminating machine for everyday use.

Before we elaborate on the characteristics of the laminating machine, look at the key advantages of films for laminating, are represented in the portfolio and the different thickness in the range 24-250 microns:

• environmental use (the film does not emit harmful substances and do not have the sharp odors);
• a high degree of coupling surfaces of dissimilar objects;
• minimum sensitivity to moisture and temperature changes;
• good resistance to mechanical damage.

Lamination of printed products is carried out using a special device - a laminator.

Today, several types of lamination are known:

• cold or hot;
• unilateral or bilateral

The structure of the laminator is represented by two devices (shafts): transit and the press. The most primitive models have only one pair of rollers, thus, combining the function of promoting and pressing. There are specialized laminators increased downforce with three pairs of rollers. The most optimal price and quality are considered twin-shaft unit (and this is enough for high-quality lamination).

Laminating hot-lamination can be equipped with one of the three variants of the heating elements:

• plate;
• front rollers;
• a combination of the heating plate and heated rollers.
• A large number of modern laminating with heating elements and support the function of cold lamination.

Depending on whether the laminating unwinding device, they are divided into roller (used roll film) and the envelope (use a separate sheet).

In addition to the distinctive characteristics of each type of laminator can be additional features: the change in velocity, temperature, turn the shaft on the opposite, remembering lamination mode, shut-cooling after the heating element.

Finally it should be noted that for cold lamination requires special film which is highly transparent adhesive system. The process of interaction with the print object takes place under high pressure.

When hot lamination to the effects of clamping force is added, and the effects of temperature.
