Linear tray sealer FL-QD-520

automaticvacuumwith modified atmosphere packaging

Overview
This automatic vacuum MAP tray sealer FL-QD-520 is engineered for modified atmosphere packaging of fresh and ready-to-eat food on medium to high throughput production lines. It integrates vacuum, gas flushing (MAP) and heat sealing in one controlled cycle to extend shelf life, minimise spoilage and preserve product appearance. The frame and contact parts are food-grade stainless steel for hygienic operation and easy cleaning.

Key capabilities

• Combined vacuum, gas flush (MAP) and sealing in a single cycle
• Multi-tray operation: 4 trays per cycle (standard tray 260×170×110 mm)
• High gas replacement rate with precise gas mixing to protect product quality
• Suitable for medium–high throughput lines (up to 700 boxes/hour)

Applications / Suitable products

• Ready meals & meal kits: complete meals, salads and multi-component trays requiring extended freshness
• Pre-cut fresh produce: herbs, sliced fruit and vegetable mixes to reduce oxidation
• Fresh meat, poultry & seafood: maintain natural colour and extend shelf life
• Bakery & pastry: protect cakes, pastries and fresh pasta from staling
• Cheese & deli slices: preserve flavour and texture of pre-sliced products

How the machine works
Operator loads filled trays into the sealing chamber. The system evacuates air (vacuum), injects a controlled gas blend (N2/CO2 ± O2 as required) to reach the target MAP composition, then heat-seals the tray with a durable sealing film. The cycle reduces microbial growth and oxidation while maintaining product appearance.
