Cheese is one of the food products with the greatest variability in packaging: from fresh mozzarella lasting 48 hours to grated parmesan reaching 12 months. Each type requires a specific technology, and getting it wrong means compromising quality, appearance and shelf life.
Packaging technology by cheese type
The choice depends on moisture content, rind and target shelf life. Fresh cheeses with high water content are incompatible with traditional vacuum (risk of crushing and whey loss); hard cheeses are perfectly suited to classic vacuum.
- Fresh cheeses (mozzarella, ricotta): MAP tray with CO₂/N₂ or permeable film
- Semi-aged cheeses (asiago, fontina, scamorza): vacuum or MAP
- Hard cheeses (parmesan, grana, pecorino): vacuum + shrink wrap
- Blue cheeses (gorgonzola, roquefort): high CO₂ MAP — vacuum crushes them
- Washed rind cheeses: N₂/CO₂ MAP to respect bacterial flora
Shelf life of packaged cheeses
Correct packaging can triple or quadruple shelf life compared to unpackaged product. At refrigeration temperature +2/+6°C:
- MAP mozzarella: 20-30 days (vs 5-7 unpackaged)
- Vacuum fresh asiago: 45-60 days
- Vacuum shaved parmesan: 90-120 days
- High CO₂ MAP gorgonzola: 30-45 days
- Vacuum + shrink whole pecorino: 6-9 months
Machines for dairy packaging
Dairy cooperatives with average production use double or automatic vacuum chambers for hard and semi-hard cheeses. For fresh cheeses in trays, automatic MAP tray sealers are used. Grated cheese lines require volumetric or gravimetric dosers combined with thermoformers.
- Whole/portioned cheeses: chamber + shrink tunnel
- Fresh cheeses in tray: automatic MAP tray sealer
- Packaged grated cheese: doser + thermoformer + MAP
- Individual slices: thermoformer with interchangeable format
