Amcor Flexibles wins Alufoil Trophy for respiratory inhaler

AirFluSal Forspiro is the winner in the Product Preservation Category

Amcor has won an Alufoil Trophy in the Product Preservation category for a blister strip used in the AirFluSal Forspiro inhaler

Amcor Flexibles has won an Alufoil Trophy in the 2015 awards organised by the European Aluminium Foil Association (EAFA) for a respiratory inhaler.

In the Product Preservation category, Amcor Flexibles, with its partner Sandoz, was awarded the trophy for the AirFluSal Forspiro, a medical device for people suffering from asthma/COPD.

Amcor Flexibles designed a blister strip to ensure a longer shelf life for the powder in the inhaler.

The strip protects the inhalation powder from moisture ingress and also improves performance during transportation and release of the powder from the cavity.

By removing the aluminium blister strip at the end of the day in the feedback window, the patient can check whether the prescribed number of inhalations has been taken.

Jean-Paul Duquet, Global Packaging Eco Design Manager of Bel Group and Head of the judging panel, said the judges had been impressed by a number the inhaler's features.

'This is a complex device and all the components had to be carefully combined to achieve the required performance. It is clear that the protection of the active ingredient – a hygroscopic powder – is entirely due to the innovative use of the aluminium foil in the blister strip.'

Duquet added: 'The powder is readied for release when the lid foil is pierced and upon inhalation the airflow transports the powder out of the cavity through the holes.'

Andrea Della Torre, R&D Pharma Director at Amcor Flexibles Europe and Americas, said: 'We are particularly proud to have won this award for our blister packaging with our partner Sandoz. It emphasises how an early and close collaboration in the packaging development process contributes to launching an innovative product for patients.'

By using a novel seal layer between its Formpack base and blister lid foil, Amcor has been able to reduce the potential for moisture ingress through cross diffusion by 50%.
