What Is Manufacturing Process of Colored Aluminum Foil

Publish: Modify: Jan 11, 2024Author: From:  Haomei

What is the production process of the colored aluminum foil? What should the colored aluminum foil roll factory pay attention to? It is related to the raw material and equipment. Learn more.

The main production process of printing and coating colored aluminum foil is to use an anilox roller to coat the aluminum foil with adhesive (protective agent) during the aluminum foil production process, and evenly disperse pigments or dyes of various colors into the adhesive and protective agent system,so that the adhesive layer (protective layer) on the surface of the aluminum foil presents colorful patterns.

If you want to get the correct color required by the user, you must grasp the coating amount of adhesive and protective agent during the process. This is a very important process indicator. If the configuration of adhesive protective agent is not accurate, the coating amount will vary greatly or the operation is not proper, all may cause uneven color.

In the printing process of aluminum foil, it is necessary to apply protective agent and adhesive on the surface of the aluminum foil, and evenly distribute pigments or dyes of various colors into the protective agent and adhesive system. The protective layer and adhesive layer appear in different colors, which requires certain choices of pigments or dyes.

Since aluminum foil is used for packaging medicines, disposable medical supplies and certain foods, the selected pigments must be harmless to the human body, stable in the protective layer and adhesive layer, and resistant to solvents and migration. It will not contaminate packaged medicines, medical supplies or food.

In addition, since pharmaceutical aluminum foil requires high-temperature heating during the coating, printing and blister packaging processes, the heat resistance requirements for pigments are also relatively high. Aluminum foil coating pigments are organic pigments that have been surface-treated with high molecular polymers. The principle of applying color to the surface of aluminum foil is to wrap the pigment particles with resinous polymers so that the pigment particles are in the protective layer and adhesive layer.

At present, there are four general ways to adjust the scraper pressure device in aluminum foil printing equipment: tension spring pressure adjustment, hand wheel pressure adjustment, cylinder pressure adjustment and hammer pressure adjustment. During coating, if the pressure of the scraper on the anilox roller is small, or even if the scraper does not press the anilox roller tightly or there are mechanical impurities on the blade surface, the scraper will be lifted up to form a gap, resulting in uneven coating.
