Choosing the Right Aluminum Paste for Environmentally Friendly Printing Inks

Printing inks can be seen everywhere in our daily life, and most of the pigments used in printing inks are aluminum pigments. Aluminum pigments have good metallic feel, excellent white brightness, uniform particle size distribution, good dispersion and resistance. It has the advantages of high oxidation performance and high cost performance. It can be used in ink to stabilize its hue. Due to the increasing emphasis on environmental protection, not all aluminum pigments can be used in inks, such as some food packaging. The requirements for pigments are very high. For the aluminum silver paste for food packaging bags, it must be free of benzene and ketone, environmentally friendly, non-toxic, and free of odor.

To people's health, so, the correct choice of a product is very important.

Aluminum paste for gravure printing is widely used in food packaging, cosmetic packaging, high-end decoration wallpaper, gift boxes, pharmaceutical packaging, tobacco and alcohol packaging, etc. Dispersion, smooth and particle-free, the product has the characteristics of rapid volatility, low odor, water resistance and so on.

Compared with traditional aluminum paste, Aluminum Granules does not contain solvent and is coated with resin, so it has better environmental protection advantages and better storage resistance. The content of benzene series is reduced, benzene series is often undetectable, and the environmental protection performance represents the high level of today's aluminum paste industry. Aluminum Granules for printing inks, with bar-like appearance, are characterized by being solvent-free, odorless and shelf-stable, in addition to the consistently excellent hiding power and white brightness of ink-aluminum pastes. When used, it only needs to be soaked and dispersed in double-quality solvent to restore the silver-white paste-like appearance. Widely used in tobacco packaging, pharmaceutical packaging, food packaging and other high environmental protection applications.
