Abstract
A leakage detection patch (10) for a modified atmosphere package comprises a substrate (12) and an oxygen sensing spot (14) arranged thereon. The oxygen sensing spot contains an oxygen indicator, which may be interrogated remotely An adhesive strip (16) for fixing the leakage detection patch to a package surface of the 5 modified atmosphere package extends peripherally around the sensing spot. The leakage detection patch further comprises means (20) enabling oxygen diffusion between the modified atmosphere and the oxygen sensing spot.
