Usually, aluminum foil bags need to go through an inkjet printing process, such as spraying the production batch number, specification, date, etc. Based on the low adhesion on the surface of the material, the print or code on the aluminum foil bags can have poor quality results during the printing and coding process.
Manufacturers have made a variety of attempts, such as replacing the ink with higher adhesion or the use of hot pressure methods to imprint labels, etc., but these methods are unable to solve this problem fundamentally.
There are often organic compounds and oxide layers such as grease and oil on the surface of aluminum foil bags. Plasma surface pre-treatment can easily solve this problem.
Before inkjet printing or coding, plasma pre-treatment would be required to obtain a completely clean and oxide-free surface.
The principle is using the characteristics of plasma to use a large number of active particles such as ions, excited molecules, and free radicals to act on the surface of solid materials. It optimizes roughness, forming many fine pits, increasing the specific surface of the material, improving the wettability of the solid surface, resulting in good quality inkjet printing and coding effect.
PL-5050 Plasma Surface Treatment System is widely used in the printing and packaging, electronics, plastic, automotive, and inkjet coding industry. For example, the pretreatment of various complex materials such as metals, semiconductors, rubber, glass, and circuit boards.
PL-5050 Plasma Surface Treatment System can be equipped with 4 various types of nozzles based on the treatment width which can be 20mm, 30mm, 50mm, or 70mm respectively. We will select suitable nozzles according to the specific processing requirements of the product, and provide our customers with the optimal solution.
