Laser Marking & Engraving for the Packaging Industry

The Importance of Laser Marking for the Packaging Industry

In today’s competitive market, the packaging industry demands precise, permanent, and legible markings to address various needs, including branding, compliance, traceability, and anti-counterfeiting. Laser marking and engraving offer versatile solutions compatible with materials such as plastics, metals, cardboard, and glass. Unlike traditional printing methods, these laser processes are non-contact, chemical-free, and capable of producing high-contrast marks that endure throughout the product’s lifecycle.

Industries such as food, beverages, pharmaceuticals, and consumer goods benefit from the reliability of laser marking and engraving. The adaptability of these technologies ensures compliance with international standards, including ISO, FDA, and CE.

Laser Marking Applications in Packaging

1. Product Identification
Laser-marked serial numbers, batch codes, and production dates facilitate seamless supply chain traceability. This capability is crucial for sectors like food, beverage, and pharmaceuticals, where accurate identification can prevent recalls.

2. Branding and Design
High-resolution laser markings enable detailed logos, custom designs, and text, enhancing the visual appeal of packaging without the risk of fading over time.

3. Compliance and Certifications
Mandatory markings, such as CE marks, FDA approvals, and recyclability symbols, are applied with precision, ensuring packages meet regulatory standards across various markets.

4. Anti-Counterfeiting
Unique laser-etched codes and security patterns deter counterfeit packaging, safeguarding brand authenticity and maintaining consumer trust.

5. Sustainability Markings
Laser processes produce eco-friendly markings, reducing waste associated with consumables like inks or labels.

The Science Behind Laser Marking in Packaging

Laser marking and engraving utilise focused laser beams to induce thermal or photochemical reactions, altering the surface of packaging materials to create high-contrast marks. This precise method ensures minimal impact on the underlying material.

Different laser types are suited to specific materials:

• Fibre Lasers: Ideal for marking metals, including aluminium cans and foil packaging.
• CO₂ Lasers: Best for organic materials like cardboard, wood, and paperboard.
• UV Lasers: Highly effective for marking plastics, ensuring high contrast without surface damage.

Advanced vision systems enhance accuracy by automatically aligning marks, even on complex packaging shapes.
