Packaging is very important to distinguish the products from the competition. It also provides protection from chemical, physical and microbiological hazards. Some packaging materials are a source of chemical impurities that affect product safety and quality. Packaging inks play an important role as it may affect the product and consumer safety. Packaging ink is a combination of various chemicals and some of them are quite harmful with the ability to migrate to the food stuff or contents after getting in contact.
The chemical contaminants get transferred from packaging inks to the foodstuff by a process known as migration. The durability of the printing ink can be tested by ink rub test. An ink rub test is performed on all labels and printed materials to ensure durability to stand the test of time. A durable label is viewed as a mark of quality. Ink Abrasion resistance tester is used to check the rubbing resistance of the printed surface of the paper, film, corrugated board etc.
