Blister packaging

A blister packaging arrangement, particularly for pharmaceutical products, wherein each dosage is recognisable by feel as well as sight, comprises first and second separate rectangular areas 11, 12 of a support member 10, each having blisters 17, 17' formed thereon, a third rectangular area 13 of the support member 10 being located between the first and second areas 11, 12, with respective fold lines 14 therebetween. The blisters 17, 17' formed on the first area 11 are offset with respect to the blisters formed on the second area 12, and the width of the third area 13 is such that when the first area 11 is folded about the fold lines 14 to overlie the second area 12 the sides of the blisters 17, 17' removably interengage one another. Two such arrangements may have a common support member 10, joined by a fourth area 15, allowing the two arrangements to be folded one on another.
