For most consumers, the set of digital codes on packaging, which includes the production date, expiration date, and batch number, is the first checkpoint for determining food safety. These seemingly simple labels are often tampered with. In this battle to protect food safety, fiber laser marking machines are becoming the most reliable guardians of the three codes on packaging bags and boxes.

一、The Security Code for Food Packaging: The Core Mission of the Triple-Period Code

Clearly marking the production date, expiration date, and batch number on food packaging bags and boxes has become a mandatory requirement for the global food industry. These triple-period codes not only provide consumers with essential food safety information but also serve as the core basis for product traceability for companies. When a food safety incident occurs, clear and accurate batch number information helps companies quickly identify the offending batch and implement targeted recalls, minimizing losses and risks to consumers.

For consumers, the triple-period code is a direct indicator of product freshness and safety. For companies, these markings carry brand reputation and legal responsibility. However, the clarity of these critical markings is directly related to the reliability of food safety information, and traditional inkjet coding technology has significant shortcomings in these areas.

二、 The Drawbacks of Ink Inkjet Coding and the Rise of Laser Marking Technology

The drawbacks of traditional ink-based coding are obvious: easy erasure, high consumables, high maintenance costs, and, more critically, the risk of chemical contamination of food. Laser marking technology fundamentally addresses these issues. It uses a high-energy laser beam to create a permanent mark directly on the packaging surface, without the need for any ink or chemicals. This feature completely eliminates the possibility of chemical contamination of food packaging, meeting the stringent safety and hygiene requirements of the modern food industry.



三、Laser Marking: An Irreplaceable Anti-Counterfeiting Guardian

When applying three-phase codes to food packaging bags and boxes, the core value of laser marking technology lies in its irreplaceable anti-counterfeiting properties. Laser marking creates a permanent physical change directly on the packaging surface, making it impossible to remove or modify by conventional means. This fundamentally eliminates the possibility of counterfeiting by using washed discarded packaging, becoming a solid line of defense for food packaging safety.

Laser marking equipments can also easily serialize products, giving each food item a unique identity, significantly enhancing anti-counterfeiting capabilities. This feature is particularly important for high-end foods and health supplements, becoming a key technical barrier for brand protection.

四、a fully protected closed loop from production to inspection

The value of laser marking extends beyond the labeling process to subsequent quality inspection systems. Even advanced laser marking equipment can occasionally produce defective products on high-speed production lines, necessitating a professional inspection system to ensure quality control.

A laser marking + visual inspection system can quickly and automatically inspect the three-phase code on packaging with over 99.999% accuracy. This system can identify defects such as misprints, missing characters, incomplete characters, and light printing, and automatically remove unqualified products from the production line.

This combination of high-speed laser marking machine and visual inspection forms a complete closed loop from labeling to quality inspection, ensuring that the three-phase code on every food package entering the market is clear, accurate, and tamper-proof.

With increasingly stringent food safety regulations and growing consumer awareness, laser marking technology has evolved from a simple production tool to a bond of trust between food companies and consumers. It is not only a link in the production line, but also an indispensable part of the modern food safety assurance system.
