Oval Cosmetic Tube

There are differences between the round and oval tube for their production procedures. Thus, today people would prefer to discuss about the question they met in the communication for the oval cosmetic tube.

Dry conditions including drying box structure, length, air velocity, air temperature, such as printing price, they determine the printing quality drying efficiency. Poor drying, solvent residue will increase. Increase the air velocity, air temperature, can improve the efficiency of drying, but ink layer thick, also may be the cause of the ink layer surface of dry quickly, preventing the transgression of solvents in the ink layer, which resulted in increased solvent residue. In addition, the drying device should be regular maintenance, cleaning, avoid congestion.

Printing speed determines the printing quality of the length of the drying time, should be fully guarantee the printing ink layer drying conditions gradually improve printing speed.

The humidity of drying medium (air) has a great influence on the solvent residue. A small printing press is the moisture in the air into the ink, is bound to cause of comprehensive volatile solvent variation; 2 it is abundant moisture, drying medium also inhibits the evaporation of the solvent.

For Double moisture, the ink drying speed will be delayed nearly two times. So under the condition of high humidity, we should try to slow down the printing speed and reduce the ink contact with air, to ensure that the ink to fully dry. At the same time it should immediately adjust solvent formula, preparation special formula is suitable for the climate. Printing workshop air humidity generally should not be more than 70%, of course, it is also cannot too dry, otherwise it will cause the electrostatic problems for the oval cosmetic tube.
