What's the cold marking of uV laser?

Cold marking has become a popular processing way in laser marking manufacturs, its principle is not using thermal processing to engrave or etch a material, cold marking creates marks with a photochemical reaction that changes the surface of a substrate. This no-contact, no-heat process delivers numerous benefits for various industries.

 

Unless the precision, versatility and efficiency of cold marking, many industries now rely more on UV laser marking than traditional alternatives.

Why use laser marking for food packing?

1.More safe

 Laser marking is often non-contact and doesn't require the use of chemical inks or other marking materials. This helps reduce environmental pollution and potential risks that chemicals might pose to food products. Inkjet marking involves ink that may contain chemicals, raising concerns about food safety and the environment. Numerous studies indicate that laser marking doesn't cause any changes on the surface of products.

2.High efficiency

 UV laser machine with its high speed galvometer scanner, power laser source, fast engraving speed suitable for mass production, saving a lot labor cost and processing time,increase produce efficiency.

3.Anti-fake function

 Laser engraving machines utilize high-energy density laser beams to achieve fine details, with surface markings as thin as 0.1 millimeters. This innovation opens up possibilities for precision processing and anti-counterfeiting technology. It effectively shapes product appearances and brand effects.The skin's protective functions remain unaffected, and shelf life remains unchanged, if use ink marking some manufactures may change the shelf life, customers suffer from expired goods.

4. Permanent marking

 Laser marking is an extremely durable identification method that remains unchanged under various environmental conditions. It is less susceptible to external factors like temperature, humidity, and light. This ensures that identification information remains attached to the packaging over time and doesn't fade or blur due to the passage of time or changing environment.

Why use laser marking for food package?

Compared with traditional marking methods, laser marking is a permanent marking technique that doesn't fade due to environmental changes. It employs high-density energy from a laser to instantly vaporize or chemically react with the surface material, generating a mark. This process requires no auxiliary tools, and the marked information is clearly distinguishable to the naked eye. Additionally, it doesn't consume consumables like inkjet coders, thereby enhancing packaging security and minimizing environmental pollution. This aligns with the direction of modern green industry development. 

 

 Laser marking represents a novel approach distinct from traditional marking methods. It breaks free from the limitations of uniform and standardized marking, allowing for diverse and customized marks according to practical needs. This enhances a product's competitiveness in a fiercely competitive market.
