[China Packaging Network News] Examining the current state of the daily chemical industry, both large international brands and emerging domestic labels are increasingly prioritizing anti-counterfeiting measures. The challenge lies in how to effectively prevent counterfeiting and ensure product authenticity.
From simple production dates and expiration periods to batch numbers, barcode recognition, and two-dimensional codes, these features not only meet traceability requirements but also serve as key tools for anti-counterfeiting and ensuring product integrity.
How to Identify the Production Date on Cosmetics
On cosmetic bottles, you often see a series of letters and numbers on the label, which is typically the batch number. In Europe and the US, skincare products are labeled with clear batch numbers, while in Japan, they tend to be more chaotic. A batch number represents each production run, and most skincare products have a shelf life of three years, while makeup cosmetics can last up to five years.
Can the production date on packaging be removed with nail polish?
To test this, we purchased some nail polish and various types of plastic and cardboard packaging from a supermarket. After applying a small amount of nail polish with a cotton swab on the production date, the text disappeared almost instantly. After wiping away any residue, the packaging showed almost no signs of tampering.
This method works on most types of packaging, especially plastic and rigid plastic bags, where the ink is easily wiped off. Cardboard with a coating is slightly less affected, while film-free cardboard may leave visible marks.
The experiment revealed that ink-based production dates are very easy to erase. With just a few applications of nail polish, the date can be completely removed. This shows that altering production dates is not only simple but also inexpensive, making it a common method used by counterfeiters.
Laser marking technology offers a better solution to this issue.
Efficiency: Laser marking machines use imported RF lasers (metal packaged) and high-speed galvanometer scanning systems. They come with dedicated online flight marking control software, enabling continuous dynamic marking on production lines. These machines can permanently mark text, numbers, symbols, graphics, and even anti-counterfeit serial numbers. They offer a more reliable alternative to traditional inkjet printing.
Environmental Friendliness: The laser marking process is non-contact, pollution-free, and has low operating costs (no consumables). It supports both online dynamic and static marking, adapts to different production lines, and has a low failure rate, reducing unplanned shutdowns caused by equipment issues. It’s also user-friendly and safe.
Permanence: Laser marking creates a unique, permanent effect that cannot be erased or altered. It provides strong anti-counterfeiting protection, preventing issues like fake products, date manipulation, and stock picking. This makes it an effective tool for product authentication.
Printer Application Features
1. High-performance, sealed metal RF laser generator imported from the original source.
2. Equipped with a high-precision two-dimensional scanning system, offering fast speed and accuracy.
3. Increased work efficiency, suitable for high-speed production lines.
4. Eco-friendly, high-tech product meeting EU standards.
5. Danzi Water password envelope line, capable of marking 3 lines at a speed of 18 meters per minute, producing up to 10,000 bottles per hour.
Benefits
Lower Cost: Although laser printers have a higher initial cost, their long-term operational costs are extremely low, with no consumables and minimal maintenance required.
More Efficient Work: Laser printers operate continuously at high speeds without stopping, improving overall production efficiency. Unlike inkjet printers, they don’t suffer from clogging issues, reducing unexpected downtime and economic losses.
Durable Marking: Laser marking is permanent, resistant to fading, and unaffected by external conditions such as touch, acidic or alkaline gases, high or low temperatures. This ensures that the markings remain intact, giving customers greater confidence in the product's authenticity.
