Technical analysis of the food packaging printing

With rising food enterprises output,  printer using the temperature is rising.

Industrial portable inkjet printing machine at present has become almost essential equipment for industry production line, to the customer, select the appropriate technology and ink to design to meet their production materials and production environment, the solutions is essential.

At present the main difficulties in food industry are inkjet printing technology:

1, Marking in various material surface. Food packaging material and mark content variety, in different material surface to identify the different content, such as the selection of ink jet marking, there needs to be suitable for different requirements of a series of nozzle types, including small character nozzle can get high marks for quality; if use laser marking code technology, it is required to choose to rely on contrast the height adjustment, definition, variety, laser machine to obtain the precise identification effect.

2, the quality of ink jet printing, can be clear, high quality identification, printing effect and quality was the production enterprise concern. Ink adhesion is usually an important reference to the selection of ink. In the high smoothness and high density of surface should be selected high adhesion of ink, common condition to select general ink is preferred. For some to print code on food, choose the food grade ink or environmental protection ink. Immediately after the printing code for packaging products, the drying time of the ink is particularly important, optional quick drying inks, also can add hair drier device to speed up the drying of ink.

3, suitable for severe production environment and strict hygiene requirements. Food manufacturers in the choice to inkjet code machine, must be resistance to high humidity, high dust consideration. Therefore constructed of stainless steel and IP65 protection device of ink jet printer is often necessary.
