KBT450 Series – Compact & Flexible Freshness Solution. Advanced Freshness Technology for Small to Medium Production
Preserve Freshness. Improve Shelf Life. Optimize Small-Batch Production.
The KBT450 Series Vertical Modified Atmosphere Packaging Machine is a compact, vertical-type MAP solution designed for small to medium production capacities. It packages food products in pre-made plastic trays, bowls, or cups of various shapes (rectangular, square, round, triangular, etc.), making it ideal for fresh food retail, R&D labs, and specialty food producers.
By replacing the air inside the package with a controlled gas mixture, the KBT450 series can extend shelf life by 50%–500%, without artificial preservatives, while maintaining natural appearance and taste.
Core Advantages:
Clean Label Preservation: Extends shelf life naturally, reducing the need for chemical additives.
Gentle Packaging: Unlike vacuum-only packing, MAP protects the shape and texture of soft or delicate foods.
Compact Vertical Design: Small footprint, ideal for limited workshop or retail backroom space.
Flexible Output Options: Available with single or dual molds to match different productivity needs.
The KBT450 Series uses a reliable Vacuum – Gas Filling – Sealing process:
Vacuum: Air is evacuated from the tray to remove oxygen and contaminants.
Gas Filling: A precise mixture of food-grade gases (N₂, CO₂, O₂, or others) is injected.
Sealing: The tray is hermetically sealed with top film to lock in the modified atmosphere.
Compared with traditional gas flushing, this method ensures higher gas purity and lower gas consumption, resulting in more stable shelf-life performance.
Custom Mold Design: Each machine is tailored to the customer’s tray size and product requirements.
High Hygiene Standards: Constructed from food-grade SUS304 stainless steel, fully compliant with food safety regulations.
Precise Control System: Mitsubishi PLC + touch screen interface for easy parameter setting and stable operation.
Consistent Sealing Quality: Advanced temperature control and precision servo positioning ensure uniform seals.
Scalable Performance: Choose between single-mold or dual-mold configurations for higher efficiency.
Designed for industries requiring extended shelf life, moisture protection, and professional presentation.
