Fully Automatic Modified Atmosphere Packaging
Full automation removes the operator from the seal itself, which is where most contamination and misalignment enters the pack. It also means the machine has to diagnose itself, because there is nobody standing next to it watching.
Modified atmosphere packaging replaces the air inside the pack with a controlled gas mix — usually O₂, CO₂ and N₂ — so that the product's own spoilage mechanism is slowed down rather than just sealed out. Gas ratio is set per product, not per machine.
The machines below are the ones in our range that can take this job directly. Final selection still depends on tray dimensions, output per shift and how the line connects to what you already have — once those three are fixed, the configuration is mostly settled.

FAQ
What output can I expect for this application?
Across our current models the corresponding rates are roughly: RDW620V: 2100~2500; RDW500P-G: 1200; RDW700P: 2100-2500; RDW570P: 2800-3300; RDL480P: 1240-1400; RDW730P: 2700-3600 (trays/hour). Real output also depends on fill weight, how fast operators load trays and what happens downstream.
How long does a format change take?
It is mainly a mould change: typically 30 minutes to an hour depending on how different the tray formats are. For plants running several SKUs we usually quote the common moulds together so nobody waits on tooling.
How accurate is the gas mix, and does it drift?
Our mixing systems hold ±1% on the set ratio and residual oxygen below 0.5% on tray lines. Drift usually comes from a leaking seal or a worn gas line, both of which the machine flags during the daily self-check.
