The Main Direction of Milkpowder Packaging and Printing

With the people's awareness of environmental protection and health raising,benzene inks will become the main material under the direction of milkpowder printing in the short future and it is likely to become the leading ink in the next several years.

At present,plastic compound soft package is adopted in the milkpowder packaging and printing,sometimes metal cans. Plastic compound soft package printing is basically printed in plastic film , and attachs with aluminum foil and hot Polyester Film or composite filling materials.

For the common milkpowder packaging,manufacturers usually use chlorinated polypropylene resin-based ink in printing.Although the ink manufacturers have used a variety of ways to reduce toxic solvent benzene residues in the packaging, still, there is a small amount of residue.In order to avoid the remains of toxic solvent,some manufacturers has already adopted  benzene inks for printing.

However,there are still some quality problems on benzene inks printing.Also,it couldn't reach the standard in the combined strength and sealing performance.That is the reason why it is seldom used in the printing industry.As is known,benzene ink is a kind of ink using polyurethane resin as the principal.Therefore,it seldom includes benzene solvent.Using this material has lot of advantages.Even if you use a little amount of benzene solvent to achieve a certain printing effect,there will be rare remains of benzene solvent after being dried.So,enzene ink will gradually be welcomed by dairy producers.

It is reported that some ink manufacturers have also developed a more environmentally friendly water-based plastic printing ink, and has entered the test printing stages.Once the technology is appiled widely ,it will promote the application in order to ensure health and safety of milkpowder packaging.
