Packaging may look simple on the outside, but what truly protects food quality is the barrier performance behind it.
Two key factors play a major role in shelf life preservation:
• 𝐎𝐓𝐑 (𝐎𝐱𝐲𝐠𝐞𝐧 𝐓𝐫𝐚𝐧𝐬𝐦𝐢𝐬𝐬𝐢𝐨𝐧 𝐑𝐚𝐭𝐞)
Helps control oxygen exposure that can lead to oxidation, discoloration, flavor changes, and nutrient loss.
• 𝐖𝐕𝐓𝐑 (𝐖𝐚𝐭𝐞𝐫 𝐕𝐚𝐩𝐨𝐫 𝐓𝐫𝐚𝐧𝐬𝐦𝐢𝐬𝐬𝐢𝐨𝐧 𝐑𝐚𝐭𝐞)
Helps manage moisture transfer that may affect texture, freshness, and overall product stability.
Every product requires a different barrier approach.
For example:
✔ Snacks & nuts need strong oxygen protection
✔ Powder products demand moisture control
✔ Fresh foods often require a carefully balanced atmosphere
Understanding OTR & WVTR is essential when developing packaging that supports real shelf-life performance. Barrier properties are not just laboratory values. Τhey directly impact freshness, product safety, and consumer satisfaction.
