Our client in the USA uses Utien Pack’s FSC-400 Automatic Continuous Tray Sealer with Unifresh® patented skin packaging technology to pack lobster tails in pre-made trays. This solution enables secure sealing with protrusion, ensuring premium presentation, extended freshness, and reliable protection for high-value seafood.
Number of Trays: 4 trays/cycle
Production Output: 6 - 8 cycles/min
Sealing Method: Unifresh® Skin Pack with Protrusion

The client operates in a coastal U.S. region where lobster production takes place in humid, salt-rich environments. The tough working conditions required a packaging machine that could resist corrosion, remain easy to operate and maintain, and run reliably through the intense demands of peak seasons. Additionally, since lobster tails are often taller than the tray depth, the client needed a packaging technology capable of skin pack with protrusion to secure the product without compromising appearance.
Pain Points
1. Harsh production environment with humidity and salt requiring corrosion-resistant design.
2. Continuous high-volume operation during peak season, with no tolerance for breakdowns.
3. Lobster tails often taller than tray depth, requiring reliable skin packaging with protrusion.
Utien Pack provided the FSC Series Automatic Continuous Tray Sealer, designed to address the client’s key challenges:
Unifresh® skin packaging technology: Provided secure sealing with protrusion for tall lobster tails.
IP65 protection: Ensured all electrics and pneumatics were resistant to moisture, salt, and extreme conditions.
Clean mode software: Built-in function allowed the machine to be washed directly without additional steps, making maintenance simple and safe.




The new tray sealing solution fully met the client’s requirements and delivered measurable benefits:
Higher profitability: The new packaging allowed the client to shift from wholesale to retail sales, increasing margins by 30% per unit.
Reliable operation: No breakdowns reported during the first six months of continuous use.
Ease of use: Staff confirmed the machine was user-friendly and easy to maintain, even under tough working conditions.
