Gravure Printing

Company with 11 set of machines. The simplest films show a single colour or complex colorful for identification and instructions, and the maximum of up to 10 colours for advertising messages with pictures are seen in complex films. In the specific case of printing a pouch to be formed entirely of a monolayer film, such as a polyethylene film, printing constitutes the last step in the sequence of film processing. Conversely, printing is applied early in the sequence for more complex coated or laminated film structures. This ensures that by the subsequently added layers the printing is buried in the structure and the printing is protected from any probable damage due to shipping, distribution, and package handling.

Even though printing can be applied to nearly all plastic film structures, there is a significant difference between the level of productivity (film speed and yields) and the quality achieved. Lower stiffness and strength add to the difficulties of printing, for example, special techniques and care to minimize tensions is warranted when printing shrink films, as they are highly stretchable. Correspondingly, BOPP and PET even BOPA are the preferred films for printing, due to their high-quality for imaging, stiffness, strength, orientation, and high productivity.
