The solvent-free lamination process: an advanced green lamination process

The solvent-free lamination process is an advanced green lamination process. It does not have the problem of exhaust gas emission, does not need a large and complex heating blower, exhaust exhaust device, simple equipment, reduced energy consumption, simple process, and small equipment footprint. "It is suitable to reduce costs, save resources and protect the environment, so the solvent-free composite process will be the direction of the development of the composite process in the future, and it is also the general trend of food packaging in the future."

At present, the country's supervision of food safety has been significantly increased, for example, QS certification is an important national measure, and the attention of Chinese people to health and safety has also been significantly improved; In particular, the newly revised hygienic standard for the use of additives in food containers and packaging materials (GB9685-2008) will be introduced, especially for the use of solvents in adhesives and inks.

It can be seen that in today's sustainable development, we should repay the society with a healthy life. To the society: resource saving, environmental friendliness. Produce green packaging with high hygienic performance and reliability.

At present, the commonly used substrates for solvent-free composite mainly include BOPP, PET, VMPET, CPP, PE, aluminum foil, etc. When composing, materials with high rigidity and good coating performance (PET, BOPP, VMPET, etc.) are generally placed at the main unwinding station; Place the materials that are easy to stretch (PE, CPP, etc.) in the sub-unwinding station. However, it is not immutable, and can be flexibly selected according to the actual production situation, such as when the printing film is compounded with the aluminized material, in order to ensure the quality and production efficiency of the lamination, the aluminized material can be put into the main unwinding station.
