Abstract
A dose tape for use in a dry powder inhaler has blisters formed in a formpack layer. A lidstock layer is attached over the formpack layer, to seal a dose of dry powder within each of the blisters. A tear strip is attached to the lidstock layer over each of the blisters. Pulling on the tear strip shears out an area of the lidstock over the blister, unsealing the powder contents.
