Why 355nm pulsed ultraviolet laser source instead of  ink for food date coding 

Date coding is used in manufacturer industry in every field. Food products manufacturing date coding, beverage bottle manufacturing date coding, electronic products production date coding, medicine package date coding etc. There are various ways of doing it. for example, screen printing date codes, digital inkjet printing date codes, and laser date coding etc.

355nm pulsed ultraviolet laser source Marking: Eliminate the food “date game”

Food safety has been a hot topic in recent years. Nowadays, people no longer focus on the packaging, taste, price, but pay more attention to food safety. People believe that the shelf life of can be faked by removing the old warranty date and printing a new warranty date.

This one of the article about laser marking application in the contrate laser date coding application industry. It describes the advantages and benefits of laser date coding marking, as it is permanent coding on the package object whether it is plastic, glass paper or wood.
