Laser Marking

Laser marking is another food packaging marking process that is popular in the food packaging industry. Unlike the inkjet method, it is compatible with many materials and can create detailed and permanent marking, which serves the purpose required in food packaging marking.
Laser Marking Processes You Can Use for Food Packaging Marking
Depending on the packaging material and types of packaging, there are two types of laser marking processes used in food packaging.
– Laser Engraving
Laser engraving is the most popular food packaging marking process that involves using a laser beam from a laser marking machine to remove parts of a material surface. The laser food packaging printer inscribes a highly readable code on the material. Depending on the materials, laser engraving is suitable for primary, secondary, and tertiary food packaging.
Care must be taken to the power of the laser marking machine not to disrupt the integrity of the packaging materials. This is important so that it can perform its job of protecting the food product.
– Laser Etching
Laser etching is a food packaging marking process that involves the inscription of code on the packaging material by melting and expanding its surface. The formation of the raised mark leads to the marking. There are few compatible materials based on laser etching. Therefore, it is more suitable for secondary and tertiary packaging.
Why You Should Use a Laser Food Packaging Printer

Below are a few advantages of using a laser food packaging printer.
– It Does Not Consume Ink Cartridges
Most people prefer laser marking processes to inkjet marking because of the cost of ink cartridges. Instead of using ink cartridges, the laser marking processes highlighted above use laser beams for quality marking. This is one of the most important things to consider when choosing any of the methods.
– Precision and Accuracy
This is one of the reasons why many people use laser marking processes, and it also applies in food packaging. Laser marking machines are accurate and precise, which is evident in the efficiency of the process.
– Materials
Laser marking machines can mark a wide variety of materials. Therefore, the process is suitable for marking any type of food packaging, irrespective of the material. This put it at an advantage over inkjet printing. However, do well to note the post-integrity structure of the material on the use of laser marking before using a laser food packaging printer.
– Productivity
Laser marking is a highly productive process known for its effectiveness and outright efficiency. For example, the recommended machine is suitable for batch coding of food packages.
– Product Compatibility
Laser marking is very compatible with food packaging materials and their content. Therefore, there should be no fear of using it in food packaging marking.
Limitation of Using a Laser Food Packaging Printer
Below are a few reasons that could make you consider other methods instead of laser food packaging marking.
– Laser Food Packaging Printers are Expensive
This is one of the reasons many people opt-in for inkjet printers. Most laser marking machines, when compared to inkjet printers, is very expensive. In terms of productivity, they are also lesser when compared to inkjet printers.
– Materials
Laser marking machines are compatible with many materials. Nevertheless, some materials used in food packaging, such as nylon, are easily ruptured when laser marking machines are used. This is not possible with inkjet printers.
