What packaging does dairy need?
Dairy needs packaging matched to each product's sensitivity: milk and infant-formula powders need an ultra-high oxygen and moisture barrier plus nitrogen flushing; cheese needs a modified atmosphere to control mould; butter and ghee need an oxygen and light barrier to prevent rancidity; and cups need clean, peelable lidding. Fat oxidation, moisture uptake and light are the common enemies.
How should milk powder be packaged?
Milk and dairy powders are hygroscopic (they absorb moisture and cake) and their fats oxidise quickly, so they demand the highest barrier plus an inert atmosphere. Best practice is an ultra-high-barrier laminate with a nitrogen flush to strip oxygen at filling — often with an oxygen scavenger for infant formula. This protects flavour, vitamins and solubility across long export shelf lives.
How is cheese packaged?
Cheese is usually packed in a modified atmosphere. Hard cheese uses a CO₂/N₂ mix with no oxygen to prevent mould and control gas-producing bacteria; sliced cheese uses easy-peel lidding on high-barrier trays. See the MAP guide for the gas-mix detail.
Dairy packaging by product
| Product | Key need | Typical pack | BARRIXA™ grade |
|---|---|---|---|
| Milk / infant powder | Max O₂ + moisture barrier, N₂ flush | Stand-up pouch / sachet | ULTRA |
| Hard cheese | MAP (CO₂/N₂), high barrier | Barrier pouch / lidded tray | PRIME |
| Butter / ghee | O₂ + light barrier | Spout pouch / lidded tub | PRIME |
| Yogurt / dairy cups | Clean peelable seal | Cup + easy-peel lid | PRIME |
Which BARRIXA™ grade should dairy use?
Match the grade to the product: BARRIXA™ ULTRA for oxygen-critical milk and infant powders, and BARRIXA™ PRIME for cheese, butter, ghee and cups. Explore the film options in High-Barrier Films and Easy-Peel Lidding.

Talk to an Expert →Frequently asked questions
Why does milk powder need nitrogen flushing?
Milk powder's fats oxidise and it absorbs moisture readily. Nitrogen flushing removes oxygen at filling, protecting flavour, vitamins and solubility across long shelf lives — often paired with an oxygen scavenger for infant formula.
How is cheese kept fresh in a pack?
Cheese is usually packed in a modified atmosphere — a CO₂/N₂ mix with no oxygen — to prevent mould and control bacteria, in a high-barrier pouch or a lidded barrier tray.
What packaging is used for yogurt cups?
Yogurt and dairy cups use a barrier cup sealed with an easy-peel lidding film that opens cleanly while maintaining a hermetic seal during shelf life.
Which BARRIXA grade is best for dairy?
BARRIXA™ ULTRA for oxygen-critical milk and infant powders; BARRIXA™ PRIME for cheese, butter, ghee and cups.
