Customer requirement<\/h2>\n\n\n\n

A company specialized in the production of sustainable detergents and eco-cosmetics needed to mark its bags with expiry dates and product batch information.<\/p>\n\n\n\n

The goal was to achieve clear, permanent, and fast marking, suitable for a high-volume production process, while ensuring continuous and reliable printing performance.<\/p>\n\n\n\n

Proposed solution and machine used<\/h2>\n\n\n\n

To meet this requirement, an automatic rotary marker FPMR 420<\/strong> was proposed, designed for fast marking on flat products such as bags and flexible packaging.<\/p>\n\n\n\n

The system uses proven solid ink roller technology: the ink is activated through heating, ensuring immediate drying and permanent printing on different types of materials.<\/p>\n\n\n\n

The product is loaded into an adjustable magazine; an automatic feeder picks up each individual bag and transports it through flat belts under the printing roller, ensuring precise and consistent marking.<\/p>\n\n\n\n

Test carried out<\/h2>\n\n\n\n

During the test, bags intended for eco-cosmetic products were tested, verifying the machine\u2019s ability to handle a continuous production flow.<\/p>\n\n\n\n

The video shows the automatic feeding and marking process, with the expiry date applied quickly and uniformly.<\/p>\n\n\n\n

The machine demonstrated the ability to print on both the front and back of the bag, while always maintaining high print quality.<\/p>\n\n\n\n
