In the packaging industry, clear and durable markings are essential for product information, brand image, and regulatory compliance. PET packaging marking equipment plays a key role in achieving this, as PET is widely used in beverage bottles, food containers, and cosmetic packaging.
Laser Marking: Permanent and High-Quality
Laser technology, especially CO₂ laser markers, delivers permanent, high-contrast codes with a frosted effect on PET surfaces. It ensures non-contact, efficient marking without damaging thin bottle walls.
For heat-sensitive PET materials, UV laser markers (355 nm) offer “cold processing,” creating precise, high-contrast marks with minimal thermal impact. They are ideal for complex shapes, multilayer packaging, QR codes, and fine text.
Inkjet Printing: Flexible and Versatile
Inkjet printers provide a cost-effective and adaptable solution for PET bottles and containers. Continuous inkjet (CIJ) systems from brands like Meenjet or Videojet offer high-speed, non-contact coding. A wide choice of inks—fast-drying, food-grade, removable, or high-contrast—ensures compatibility with different production needs.
For example:
Meenjet MX1890 delivers high-speed, high-resolution printing with reduced downtime.
Videojet 2980 is designed for ultra-fast production lines while maintaining durable, clear codes.
Choosing the Right PET Packaging Marking Equipment
Selecting the right system depends on production speed, packaging type, and marking requirements:
Laser marking ensures permanent, maintenance-free, eco-friendly coding.
Inkjet printing offers flexibility, lower upfront costs, and wide ink options.
By understanding production needs, material properties, and cost factors, manufacturers can choose the most effective PET packaging marking equipment to improve efficiency, ensure compliance, and strengthen product branding.
