Permanent CO2 Laser Marking for Food And Drug Packaging Traceability

With the continuous improvement of global food and pharmaceutical industry regulatory systems, product traceability, anti-counterfeiting control, and compliant coding have become mandatory standards for enterprise production and sales. Traditional inkjet coding technology has long suffered from significant drawbacks: the printed text is easily erased and rubbed off, has poor abrasion resistance, and is prone to fading and blurring during warehousing, transportation, cold chain storage, and end-sales processes. This not only affects product appearance but also leads to missing traceability information, making it impossible to pass domestic and international quality inspections and customs audits. Furthermore, inkjet coding requires continuous consumption of consumables, resulting in high operating costs, and the chemical components of the ink can easily cause packaging contamination, failing to meet the clean and safe production standards of the food and pharmaceutical industries.

To address the industry pain points of coding food and pharmaceutical packaging, the new CO₂ laser coding solution is specifically adapted to various packaging materials, abandoning the traditional consumable-based coding mode and achieving fully consumable-free green marking. The equipment can accurately and permanently etch various information such as production date, batch number, expiration date, traceability QR code, and unique anti-counterfeiting code. The marking marks are clear, firm, and never peel off, unaffected by friction, temperature differences, humidity, and other complex environments. This eliminates tampering, counterfeiting, and cross-selling at the source, establishing a unique product identity traceability system.

This laser coding solution is highly compatible, perfectly adapting to both static stand-alone marking and high-speed on-line marking modes, without affecting the company's original production rhythm and suitable for large-scale mass production. It fully complies with domestic and international food and drug safety traceability compliance standards, helping companies simplify production processes, reduce maintenance costs, and enhance brand anti-counterfeiting capabilities, assisting food and pharmaceutical companies in achieving intelligent, standardized, and compliant packaging coding upgrades.

1. Precise Batch Information Coding, Adapted to High-Speed Mass Production Lines

The equipment features intelligent batch coding capabilities, automatically and accurately marking various static and dynamic information such as production date, batch number, expiration date, production shift, and product serial number. The system supports automatic data redirection and real-time updates, eliminating the need for manual coding and completely avoiding errors and garbled codes caused by manual operation. The marking fonts are neat, clear, uniform in depth and position, exhibiting extremely high consistency, perfectly adapting to the high-speed automated production line rhythm of the food and pharmaceutical industries. The entire marking process is stable and smooth, with no duplicate codes, missing codes, or ghosting even at high speeds, fully meeting the needs of enterprises for large-scale, continuous, and standardized packaging coding production, significantly improving production line efficiency.

2. High-Speed Dynamic QR Code/Barcode Marking for End-to-End Traceability

Addressing the traceability and control needs of food and pharmaceutical products, the equipment supports high-speed and accurate marking of various code types, including variable dynamic QR codes, anti-counterfeiting barcodes, and traceability barcodes, adapting to the industry's mainstream one-item-one-code traceability system. Each product can be independently bound to its own data information, completing the data association and binding of origin information, production batch, quality inspection report, distribution chain, after-sales information, etc. Consumers and buyers can scan the code to query the entire production, quality inspection, and distribution records of the product with one click, realizing full-chain visual traceability from production, warehousing and logistics to terminal sales. The code scanning recognition rate is high and the error tolerance is strong, unaffected by packaging wrinkles and minor wear, ensuring the long-term stable operation of the traceability system and helping enterprises achieve compliant traceability and transparent production.

3. Laser surface etching permanent marking, strong anti-counterfeiting and anti-diversion

Unlike the surface adhesion mode of traditional ink spraying, CO₂ laser coding uses a precision surface etching process, and the mark is directly formed on the surface of the packaging material. After forming, it is firmly embedded in the material and has extremely strong resistance to friction, wiping, high and low temperature, and moisture. The labels cannot be tampered with, removed, or modified through methods such as wiping with alcohol, polishing, or covering with film, thus eliminating industry malpractices such as product counterfeiting, information alteration, and price gouging at the source. These stable and permanent anti-counterfeiting labels effectively maintain brand market order, prevent the circulation of counterfeit and substandard products, and significantly enhance product credibility and brand recognition, meeting the quality control and brand protection needs of high-end food and pharmaceutical brands.

This CO₂ laser coding equipment is specifically optimized and calibrated for various non-metallic packaging materials in the food and pharmaceutical industries. It is compatible with most mainstream packaging materials on the market, providing clear marking results with high contrast and strong stability, fully meeting the industry's compliant coding and traceability requirements. The equipment has been specially adapted to the absorption characteristics of different materials, ensuring no damage to the packaging surface, no breach of packaging seals, and no discoloration, burning, or odor, complying with food and pharmaceutical safety production standards.

The equipment is stably compatible with various paper packaging materials, including pharmaceutical cartons, food gift boxes, paper labels, and paper labels for medicine bottles. The marking is precise and clean, with no yellowing, fuzzing, or penetration damage, ensuring a neat and high-end packaging appearance. It is also perfectly compatible with commonly used pharmaceutical aluminum-plastic blister packaging, laminated plastic packaging, and colored laminated outer packaging, achieving high adhesion and high-definition permanent coding on smooth laminated surfaces, effectively solving the problems of easy peeling, slippage, and scratching of coding on laminated materials.

In addition, the equipment is widely compatible with various flexible packaging materials in the food industry, including food composite films, snack packaging bags, and soft packaging films for daily chemical foods. It supports high-speed flight marking, ensuring that the marking does not deform, puncture, or affect the packaging's airtightness. It comprehensively covers most non-metallic packaging scenarios in the food, pharmaceutical, health product, and daily chemical consumable industries, demonstrating strong versatility and meeting the unified coding and traceability needs of different product lines and multiple product categories.
