Permanent Glass Marking: Laser Etching for Superior Durability

In the world of glass printing, achieving permanent, high-resolution codes can be a challenge. Traditional methods like ink printing can be susceptible to smudging, fading, or removal by moisture. This is where laser etching glass emerges as a superior solution.

Benefits of Laser Etching Glass:

• Permanence: Laser etching creates microscopic cracks on the glass surface, producing permanent marks for serial numbers, tracking codes, and alphanumeric data on clear or colored glass.
• Tamper-proof: Unlike printed labels, laser-etched codes are virtually impossible to alter or remove, ensuring product authenticity and preventing unauthorized tampering.
• High-Resolution: Laser etching delivers crisp, high-quality codes that are easy to read and scan, enhancing brand confidence and consumer trust
• Durability: Laser-etched marks withstand harsh environments, including moisture, abrasion, and chemicals, ideal for applications in food & beverage, and pharmaceuticals.
• Production Speed: Laser etching systems are faster than traditional methods like hot stamping or pad printing, making them ideal for high-volume production lines.

How Laser Etching Works:

Unlike marking plastic (melting the surface), laser etching glass utilizes a different principle. The laser beam rapidly heats the glass surface, causing natural fractures to occur. This controlled process creates micro-cracks that form the desired code or design.

Applications:

• Serial Numbering: Laser etching is ideal for creating unique serial numbers on glass bottles, vials, and jars.
• Internal Tracking: Manufacturers can utilize laser etching for internal tracking codes to facilitate product management and traceability.
• Date & Lot Coding: Laser etching allows for on-the-move coding of dates, expiry codes, and lot numbers directly on glass bottles during production.

Advantages over Traditional Methods:

• Laser etching offers superior permanence and durability compared to printed labels.
• Unlike hot stamping or pad printing, laser etching is faster and more efficient, ideal for high-speed production lines.
