Cambridge Design Partnership is launching the sealing method for dry powder inhalers at next month’s Drug Delivery to the Lung (DDL21) conference in Edinburgh, Scotland.

Tom Oakley, partner at the firm, which provides consultancy and product development expertise in healthcare and other markets, said that current heat-sealed drug compartments are limited to simple shapes because excess foil causes wrinkles and therefore leak paths.

Cambridge Design Partnership has developed a multi-surface sealing method for aluminium foil, which allows moisture-tight compartments for many weeks of treatment to be created in one operation.
