CA 2741978

It is disclosed a packaging material for a pharmaceutical product. The packaging material comprises a coloured element which at about 38°C discolours partially, revealing a marking. The element is formed by a first portion forming the marking printed with conventional ink, and a second portion printed with thermochromic ink. The thermochromic ink is coloured below about 38°C and becomes colourless when this temperature is reached or exceeded. The two portions are arranged so that the first portion is invisible below about 38°C, but becomes visible when this temperature is reached or exceeded.
