Laser marking food has emerged as a revolutionary technique that offers numerous advantages over traditional labeling methods. This innovative approach not only enhances food safety and traceability but also contributes to environmental sustainability.
Traditional food labeling methods often involve the use of inks, adhesives, and packaging materials that can potentially contaminate products or harm the environment. With laser engraving, this issue is avoided, offering a more hygienic and efficient method.
Laser marking eliminates the need for these materials, creating a direct and hygienic method of marking food items. By using a high-powered laser beam to etch information onto the food surface, laser engraving ensures product integrity while reducing waste and environmental impact.

Many industries now use laser engraving and cutting technology to manufacture high-quality metal, plastic, wood and fabric products and parts. These systems are also valuable in preventing product counterfeiting through accurate labels and bar codes. With the emergence of new laser applications, more and more amateurs and hands-on people are recognizing the creative advantages of affordable laser engraving machines. An emerging application of these two devices provides a different form of practical and artistic support: processing, branding and customized edible food products.
International distributors of fresh organic fruits and vegetables, are removing packaging and labels from its products by using CO2 laser to naturally mark fruits and vegetables before shipment. The use of laser engraving for natural brand promotion is becoming more and more popular, especially in the organic food industry, which needs to use direct labels to distinguish organic food from traditional fruits and vegetables. Laser engraving food is safe, non-toxic and efficient, and replaces plastics harmful to the environment. One distributor said that by eliminating plastic and other packaging materials from avocados alone, 750,000 plastic flow packaging could be saved this year.
Laser engraving is usually used in the food industry to process containers and packaging bags, but it can also be used to make cakes, biscuits, chocolate bars and even toast. This opens the door to artistic personalization and creative goods. Like any other substrate, when you laser engrave food, you burn the surface slightly to produce depth and contrast. Since many foods - especially baked goods - are sweet, you may notice a slight caramel taste, depending on what you're eating. Japanese researchers also demonstrated how to use a desktop industrial laser engraving machine (usually used to cut or carve patterns on plastic, wood, and metal) to cook ingredients according to shape and composition, so as to make a variety of charming food. In a successful cooking experiment, they used a trained webcam to guide the light beam and laser engraving to cook bacon fat.
In recent years, people are more and more sensitive to the impact of production process on the environment. Manufacturers are trying to simplify the use of resources and materials and shift to more environmentally friendly production methods.
Laser labeling of food with laser marking: This is a natural branding! This phenomenon is called "natural branding", especially the packaging of fresh fruits and vegetables. In short, the natural branding is to replace the ordinary physical label pasted on the surface of fresh fruits and vegetables with the "natural" label obtained by laser marking. For the packaging industry, this means an overall reduction in the materials that make up the packaging products: cardboard boxes, packaging paper rolls and plastic films are being replaced by biodegradable similar products, or just discarded.
Food laser labeling is a special application of CO2 laser marking. In the previous article, we evaluated the efficiency of laser engraving on organic materials such as wood or leather. Even food can be marked effortlessly. Broadly speaking, the laser marking process depends on the high energy density transmitted by the laser on the work piece surface. It is this process that produces the required marks on the surface.
The labeling process marked by CO2 laser is suitable for any kind of fruits and vegetables. However, the best result is to use fruits and vegetables with wood or thin skin, such as tomatoes, apples, grapefruits, walnuts, chestnuts, coconuts, pumpkins, etc. In this area, pieces of information can also be marked, such as product traceability codes, expiration dates, manufacturer logos and other personalized information.
By laser engraving logos and bar codes on food, you no longer need traditional plastic packaging or label stickers. Laser engraving food is not only more eco-friendly, but also natural brands are non-toxic, safe and efficient. In addition, in the long run, it is more cost-effective to choose to use laser engraving machines to mark food.
Nowadays, consumers pursue both quality and safety in the products they buy and consume. Companies in the food and beverage industry need reliable and efficient laser coding technique to ensure the quality of their fruits and vegetables and locate production batches quickly and accurately in case they need to be removed from circulation. Laser coding technique was developed to control the traceability of food from farm to table, or "farm to fork" as the department usually knows. The objective is to have overall control over all products from origin to distribution point. This control starts from the farm of agricultural products (including animals, fruits and vegetables), passes through the food processing industry, and ends at the store distributing agricultural products to consumers, and includes all agents intervening in the transportation and logistics of agricultural products.
Laser coding and labeling technology in the food industry. Although ink coding is traditionally the most widely used technology in the food and beverage industry, laser coding is becoming more and more popular because of its versatility, durability, cleanliness and durability.
Its uses range from marking and coding on fruit and vegetable trays to cutting or micro perforated plastic films to ensure air circulation in fruit containers such as strawberries.
The benefits of food labeling are manifold:
Although many companies and insiders advocate that laser marking is a faster and more reliable method of traditional manufacturing methods, there are not so many voices that emphasize that the technology can obtain greater returns from an environmental point of view. Even in the branch of product labels, the benefits are obvious and amazing. Laser marking eliminates the need for unsustainable and solvent based inks and paper and plastic label materials. This in itself makes manufacturing methods more sustainable. More importantly, laser marked product containers are easier to recycle in standard material recycling facilities. From the perspective of customers, a brand will also get some scores if it adopts a "more environmentally friendly" method in its manufacturing process.
Use laser technology to personalize food by laser engraving. By doing so, you can deliver information, brand your company, and even use food that can be distributed to guests at any event. Why not try to provide laser engraved food to meet client’s needs in a unique way? From fruits, biscuits, biscuits, vegetables and eggs, many foods can be successfully laser engraved.

The most unique examples of laser engraving we've ever seen is a laser sandwich. Whether you are dining on the spot, looking for catering options, or even want a sandwich, you can "engrave" your name or personalized information on the bread. If you want more examples of crazy laser engraving, please read on.

If you plan to use your laser engraver to customized food, blow foods also for your reference.
Next, let’s look at some tips of laser engraving food.
Here are some basic considerations to keep in mind when engraving edible items such as fruits:
Step 1. Place the toast on the working table.
Step 2. Adjust laser head by operating the control panel, press auto-focus button
Step 3. Enter the tested parameter settings.
Step 4. Press the Start button to initiate the engraving process.
Step 5. Complete the work.
Laser marking is a safe process. Labeling only affects the outermost skin of fresh agricultural products; All sensory properties of food are respected. Their taste, color or smell will not change. And the shelf life remains unchanged: some papers also emphasize that laser marking will never reduce product quality. Laser marking of fresh products is an application to be explored. This possibility is broad and allows companies to significantly improve their environmental footprint.
