Ever noticed bubbles forming on your product labels?
This happens with paper-based labels in high-humidity environments (over 70% RH).
When refrigerated, they absorb moisture from the air. But here’s the catch: • The label film is already set, so absorbed moisture causes wrinkles • Moving back to room temperature makes the label lose surface moisture Pro tip: Always apply surface lamination or varnish coating to prevent bubbling and wrinkling!
