MACSA APPLICATION
In the food sector, packaging trends prioritise solutions that are environmentally sustainable, enhance customer experience, and, most importantly, uphold food safety standards. In this context, cardboard is one of the most widely used materials in the manufacture of dairy packaging due to its effective thermal insulation, light protection and recyclability, preserving the quality of dairy products throughout the supply chain. Its light weight makes it easy to transport, while its versatility allows for design customisation and adaptation to various shapes.
In terms of food safety, laser marking emerges as a great ally, surpassing traditional ink methods, by providing accurate and durable markings, meeting the highest traceability standards.
Laser marking on cardboard offers significant advantages, such as precise coding on high-peed production lines, high accuracy in the reproduction of details, durability of the marking, and the ability to work with various types of cardboard, including coated or specially finished ones. Additionally, laser technology is environmentally friendly as it requires no consumables and generates zero waste, contributing to efficient and eco-conscious marking. The non-contact marking process also prevents the wear and deterioration of the packaged product.
MACSA SOLUTION
In this application news, we coded with a CO2 laser on painted cardboard cheese trays. The CO2 laser’s precision and versatility allow the light beam to strike the cardboard in a controlled manner, removing the surface layer of paint. The resulting marking, featuring a lot number and expiration date, is highly legible and accurate with exceptional sharpness.
The color of the cardboard plays a role in the visibility and intensity of the marking, with dark coloured backgrounds (blue, black, green, brown…) offering higher contrast compared to light colored backgrounds such as yellow and orange. However, dark colour reserves can also be applied to highlight markings on these lighter-coloured backgrounds.
