<p>A multi-component blister pack in which the blister sections are formed from a composite material with at least two layers, at least one of which is essentially impermeable to gas (especially oxygen) and shows a lower tensile elongation at break than the other layer(s). Packaging (1) with at least two storage compartments (2, 4) for the packaged substance, each being formed by a blister section (2', 4') and a cover section (2, 4) and capable of being brought at least partly in contact with one another, and in which at least one of the blister sections (4') is more permeable to gas, especially to oxygen, than the other (2'). The blister sections (2', 4') consist of a composite material (10) with at least two layers (12, 14, 16), at least one of which (14) is essentially impermeable to gas (especially oxygen) and shows a lower tensile elongation at break than the other layers (12, 16). An independent claim is also included for a method for the production of (1) by making a composite material (10) as above, forming blister sections (2', 4') as above and sealing the blisters with a cover (2, 4) to as to form adjacent compartments (2, 4) which can be connected together.</p> |
