The Importance of Labeling in Food Traceability

Food traceability requires laser equipment for labeling, as it creates visible, durable marks on packaging that inform consumers about the product's value category. Additionally, it provides details on food protection, traceability, and shelf life.

At Vinssa, we offer specialized laser machines for food traceability that are efficient, reliable, and optimize your production system while ensuring product quality.

The Laser Marking Process for Food

Laser marking for food uses CO₂, vanadate, or ultraviolet (UV) laser technologies to engrave information such as expiration dates, logos, or serial numbers directly onto food products or their packaging. This non-invasive method reacts only with the surface layer of the food, preserving its quality, taste, and safety.

Some examples of foods that can be laser-marked include:

Fruits: Apples, mangoes, oranges, lemons, and limes.
Fruits: Eggplants and potatoes.
Baked Goods: Breads and cookies.
Dairy: Cheese, milk packaging.
Others: Eggs.

Bottle and Food Packaging Markers

For containers such as glass, plastic, or Tetra Pak bottles, bottle markers provide effective solutions for ensuring clear and precise identification.

These machines are ideal for engraving QR codes, expiration dates, and other food traceability data, even on curved or difficult-to-mark surfaces.

¿Why Use Food Traceability Solutions?

¿Por qué utilizar la trazabilidad de alimentos

Food traceability softwares track food products and their ingredients throughout the supply chain, from production to final sale. In any industrial sector, traceability is essential for organizing, tracking, and locating food products to reduce the risk of foodborne illnesses while increasing consumer confidence.

Food marking plays a key role in traceability by integrating food labeling systems with coded identifiers. Common systems include barcodes, serial numbers, and data matrix codes.

Benefits of the implementation of Food Traceability Solutions

Integrating food traceability solutions into your production process offers the following benefits:

Quality Control: los marcadores láser ofrecen a las empresas el mejoramiento de su proceso de producción, debido a la trazabilidad sobre el proceso de envasado para identificar los puntos que necesitan control de calidad.
Product Recalls: marcar los productos con identificadores particulares posibilita el rastreo para la empresa y la seguridad alimentaria para el consumidor.

Operational Efficiency: la trazabilidad de alimentos optimiza tu producción de empaques, disminuye el desperdicio de materia prima e incrementa la eficacia. Análisis de raíz de la causa: la información que viene en los identificadores es de gran utilidad para los fabricantes, debido a que identifican las causas desde la raíz para evitar posibles errores.
Root Cause Analysis: la Administra de Alimentos y Medicamentos (FDA) utiliza la información que genera el proceso de trazabilidad en los etiquetados para mantener los registros de cada producto
Regulatory Compliance:The FDA uses traceability data on labels to maintain records for each product.

Three Applications of Food Labeling and Traceability

Food packaging marking is one of the main areas where laser markers generate crucial traceability information. Here are some key applications:

QR Codes: A code made up of pixel groups within a square grid.

Barcodes: A series of parallel black-and-white bars forming a group of characters and numbers. In the food sector, retailers use barcodes to track inventory, sales, and reorders.

Data Matrix Codes: Two-dimensional barcodes with black and white cells that store information within columns and rows.

Frequently Asked Questions About Laser Marking for Food

¿What is laser marking for food and how does it work?

Laser marking for food uses laser technology to engrave information directly onto food surfaces or packaging, such as expiration dates, lot numbers, and QR codes, without affecting product quality.

¿What advantages does laser marking offer over other food labeling and traceability methods?

This method is sustainable, precise, and long-lasting. It eliminates the need for adhesive labels or ink, reducing costs and waste. The markings are also permanent and resistant to extreme conditions.

¿What types of food can be laser-marked?

Laser marking is ideal for fruits like apples, oranges, mangoes, and lemons, as well as products like bread, cheese, eggs, eggplants, and potatoes.

¿Is laser marking for food safe?

Yes, it is completely safe. The process does not generate waste or use chemicals that could contaminate food. It only affects the surface layer, preserving product quality and safety.

¿What is food traceability, and how does laser marking help?

Food traceability is the ability to track a product throughout the supply chain. Laser marking facilitates this process by engraving clear, permanent information for effective tracking.

¿Can a bottle marker be used for liquid or packaged products?

Yes, bottle markers are ideal for engraving information on glass, plastic, or Tetra Pak bottles, ensuring precise labeling for liquids such as juices, dairy products, and oils.

¿What are the most common applications of laser marking in the food industry?

Applications include engraving expiration dates, QR codes, logos, lot numbers, and other relevant data on fruits, vegetables, bread, cheese, and packaging such as bottles or cans.

¿What types of lasers are used for food laser marking?

The most common laser types are CO₂, ultraviolet (UV), and vanadate. Each is suited to different materials and marking needs based on the food product or packaging.

¿How does laser marking improve the efficiency of food labeling and traceability?

As an automated process, laser marking reduces production times, ensures precision, and minimizes labeling errors, optimizing the entire supply chain.

¿What are the requirements for implementing laser marking for food?

A company needs a suitable laser marking machine, such as the Telesis models available at Vinssa, and a process aligned with food traceability regulations to ensure safety and compliance.
