UV ink and packaging box

UV ink photopolymerization initiator absorbs certain wavelengths of photons. The formation of free radicals or ions is stimulated by UV light. Then through the intermolecular energy transfer, so that high polymer prepolymer and a photosensitive monomer into an excited state, resulting in a charge transfer complex body; complex and constantly break the stand crosslinked cured film. UV inks for UV photons are always the most impact and the different wavelengths of light energy distribution selective absorption of UV ink was dry by UV radiation light source. Solve the match with UV inks UV light source, and help accelerate the ink drying rate, labor productivity and further improve the utilization of energy, and reduce production costs.

Squeegee printing ink is transferred from the screen version of the circle to the substrate surface by the impression cylinder supported. Web rotary screen printing that meets the requirements of a very very special effect printing scrub, Binghua, etc., but also online hot stamping holographic anti-counterfeit labels, embossing, die-cutting, easy to implement high-speed automatic printing tray.

There are many China packaging box supplier. High-grade alcohol and tobacco which are with screen printing ink thickness, graphic rich level, stereoscopic, wide printing materials and so on. Application areas of food packaging cartons gradually increased. Use UV screen printing ink, printing scrub, refraction, wrinkles and other effects on cigarette packs, which greatly stimulated the desire of consumers to buy.
