Environmental protection development of gravure printing ink
- Apr 09, 2018 -

(1) Reducing residual solvent in existing ink products.

This is mainly for the BOPP film special ink, the main countermeasures are: use of solvent release as much as possible the best link material, add additives, in order to facilitate the volatilization of aromatic hydrocarbons. However, due to the fact that the binder system itself determines that aromatic hydrocarbons cannot be eradicated, this is an inevitable product to be eliminated from an environmental perspective.

(2) No benzene type ink.

Theoretically speaking, these inks do not contain aromatic hydrocarbon solvents, but the storage, transportation, manufacturing process and use of raw materials will be more or less mixed with a small amount of aromatic hydrocarbon solvents.

(3) No benzene-free, alcohol-soluble ink.

Due to more stringent solvent residue requirements, these inks do not contain aromatic hydrocarbons and ketone solvents. They contain only esters and alcohols. They have low odor and high ink color. Their application will definitely improve the gravure printing in the field of packaging and printing. Competitiveness.

(4) Universal ink.

The ink used by a flexible packaging company is basically a type of ink corresponding to a substrate, and the ink used for various substrates cannot be used universally, resulting in an increase in the types of ink inventory for flexible packaging companies, difficulty in management, multiple on-site operation procedures, and difficulty in digesting residual ink. problem. How to recycle unused ink is one of the important issues faced by gravure packaging gravure printing companies. General-purpose inks can effectively solve the above problems, apply to a wide range of film materials, and can also bring benefits to the standardization of color management.
