Blister packaging material printing ink

Drug used for blow-cover packaging ink can be divided into two categories: one is the distribution of gliadin polyamide ink printing materials with good adhesion, gloss, wear resistance, good solvent, mainly used in plastic printing, its thermal stability can also meet the needs of aluminum printing, is the majority of medical aluminum foil printing materials. The problem with this type of ink is that ink stripping occurs when large area surface of aluminum foil is printed.

Secondly, it is a kind of vinyl chloride, vinyl acetate copolymer resin and acrylic resin as the main components of special aluminum foil ink. This is a newly developed rotary gravure printing ink with bright color, high concentration, special adhesion to aluminum foil, good transparency, good reproducibility of aluminum foil metal luster, etc. But because it is a gravure printing ink, the solvent is volatile. PTP aluminum foil used in medical printing tends to produce dry ink nodules, which deposit ink in the printing hole of the gravure roller, resulting in slurry phenomenon. If the paint is stored for a long time, it will deposit. Neither of these inks is suitable for printing on the surface of medical aluminum foil.

In recent years, with the improvement of environmental requirements, more and more coatings and packaging enterprises began to study the use of environmental coatings. At present, the domestic commonly used alcohol soluble ink using alcohol soluble polyamide production, containing trace toluene, benzene accounted for 1% of the total ink solvent, benzene soluble plastic rotary gravure printing ink 10%. Toluene and xylene should be avoided in diluent to maintain low residual solvent performance. In intaglio printing, benzene-soluble chlorinated polypropylene composite ink is alcohol-soluble polyurethane ink. Intaglio printing ink, one of the commonly used inks, has low odor, benzene, ketone - free characteristics.

Ink anti - counterfeiting technology is currently used in the pharmaceutical packaging industry as an anti - counterfeiting technology. A technique in which a special substance is added to an ordinary ink knot and a special process is used to make a special ink. Simple implementation, low cost, hidden, colorful, easy to check. At present, the main anti-counterfeiting ink pigment and uv fluorescent anti-counterfeiting, anti-counterfeiting inks, thermo-sensitive anti-counterfeiting inks, coatings and excitement, anti-counterfeiting inks anti-counterfeiting optical anti-counterfeiting inks susceptible to pressure variables, infrared anti-counterfeiting inks, anti-counterfeiting inks, anti-counterfeiting inks. Fluorescent anti-counterfeiting inks are the most widely used anti-counterfeiting inks in drug packaging, and corresponding visible fluorescent compounds are added in the packaging. Printed materials emit light in both visible and ultraviolet light. Different fluorescent dyes can be obtained with different formulations. Anti-counterfeiting visible fluorescent ink material is visible fluorescent ink printing process is simple, the printing effect is the same as ordinary ink, but in ultraviolet ink printing light is unusually bright, now, may be different from ordinary ink. Be careful when choosing anti - false fluorescent ink. In general printing systems that produce supplementary light or color wavelengths higher than those of the selected fluorescent ink, try not to use fluorescent ink.
