Traysealer for modified atmosphere packaging
In the food industry, maintaining product freshness during packaging is critical. Challenges often include preserving flavor, extending shelf life, and preventing contamination. Especially for perishable products, ensuring a vacuum or modified atmosphere inside the packaging is essential.

Seal trays with modified atmosphere efficiently
The SMART 500 by ULMA Packaging Spain is a semi-automatic traysealer designed for heat sealing food products in modified atmosphere packaging (MAP). The system seals a wide range of preformed trays and films, ensuring product-specific requirements are met. The SMART 500 carries out operations including vacuuming, gas flushing, and sealing with fully automatic cycling initiated by simultaneous activation of two start buttons. The system conforms to international ‘CE’ safety codes and ISO 9001 quality standards, and offers fast tool-less cavity changes to facilitate diverse production needs. With a performance rate of up to 8 cycles per minute for cut & seal operations and up to 5 cycles per minute for MAP, it provides medium-high output levels. Material construction is corrosion-resistant, and maintenance is simplified by easily removable covers and compliance with IP 65 standards for sanitation.
