MAP tray sealing for shelf life

Ready meals, fresh meat, deli, produce: vacuum out the air, flush in the gas mix, seal the tray. Days of extra shelf life, tested at 480 or 720 trays per hour.

What makes it tricky

MAP is a numbers game

Output numbers you can hold us to2-mold configuration: 480 trays/hour. 4-mold: 720 trays/hour. Those are tested cycle figures, not brochure optimism — and note 4 molds isn't simply double, because the cycle time differs.

Two-gas or three-gasDifferent products want different gas mixes. The machine mixes two or three gases; we confirm the right configuration for your product before quoting.

The tray decides the moldSend your tray's dimensions with your inquiry. Molds are made to your tray — changing tray later means changing mold, so we get this right first.

Common questions

Before you ask

How much shelf life will I gain?

It depends on your product, gas mix and cold chain — anyone quoting you a universal number is guessing. We'll talk through your specific product honestly.

Do I need to buy the gas system from you?

The machine handles the mixing; gas supply is sourced locally in your country. We tell you exactly what to ask your gas supplier for.

2 molds or 4 — how do I choose?

By your real daily output. If 480 trays/hour covers your peak with room to grow, don't pay for 720. We'll do that math with you.
