Laser Marking Machines for Food Packaging|Laser Marking Standards and Ink Alternatives for Food Packaging

As environmental protection policies tighten and consumer awareness of safety issues increases, food packaging technology is undergoing a revolution.The event will explore the application of laser marking technologies in packaging, examine domestic and international safety standards for laser marking of food contact materials, compare traditional ink printing in terms of cost, efficiency and environmental impact, and provide solutions to replace ink in order to satisfy regulatory requirements. The goal is to help manufacturers achieve both safety and compliance and sustainable development.

In recent years, the food packaging industry has been facing a double challenge: it has to satisfy increasingly strict food safety regulations, and also deal with the pressure to reduce the environmental impact of traditional printing inks.Laser marking is becoming a popular alternative to traditional inks.This technology uses a high-precision laser to make permanent markings on the surface of packaging materials. No chemical additives are required, so the risk of ink migrating and contaminating food is eliminated.

From the perspective of safety standards, the EU's 1935/2004 regulations, the United States 'FDA 21CFR, and Taiwan's GB 4806 series standards all require that food contact materials be marked with the relevant information.Laser etching requires special attention to the degree of carbonization of the material to avoid the production of byproducts that might affect food safety.For instance, when laser marking on plastic packaging, the different absorption rates of different materials directly affect the clarity of the mark and its safety, and require professional adjustment of parameters and verification testing.

The economics of the substitute ink solution are equally impressive.Although the initial investment for laser equipment is high, the long-term cost of labeling individual items can be lowered by 60-80 %, and there is no need to purchase, store or dispose of inks.One dairy company that switched to laser marking saved more than NT $ 2 million in annual operating costs, and received a government subsidy for reducing VOC emissions.

Nevertheless, the process of technological transformation has run into some practical difficulties.The PET labels tend to turn yellow and the glass labels tend to fall off, and these problems still need to be addressed.He recommends that enterprises take three steps: first, conduct a small-scale test of materials to determine their suitability, then establish a database of laser parameters, and finally integrate production line speeds to achieve automation.Currently the leading solutions in the industry are capable of high-speed printing at 600 items per minute, and can be integrated with visual inspection systems to ensure the quality of the markings.

The future trend shows that the combination of QR code and blockchain technology will push the demand for laser marking to increase.Selecting a supplier of laser equipment that meets the relevant standards, and establishing a comprehensive quality control system, will be key to food packaging companies 'ability to compete in the market.

Three Major Changes to Look Out for in 2024
