To guarantee our supplements' quality, freshness, and stability, we draw on a range of packaging methods. For some, our 'green' high-density polyethylene (HDPE) supplement pots are the most appropriate casing. Others, however, are more conducive to foil blister packets, which use a combination of plastic and aluminium foil to protect and encase supplements. We choose to use this packaging for the likes of Colladeen® Visage, St John's Wort, and Valerian Root Extract.
The main advantage of using blister packs is their ability to maintain the stability of our products. Blister packs place supplements in individual pockets under optimal sanitary conditions. They act as an exceptional barrier against oxygen and moisture – both of which risk spoiling our nutritional formulas. For supplements that are more fragile, blister packs also offer a long-lasting and immediate guarantee of their integrity.
Aside from this, stability studies are typically performed on one blister foil, which contains 15 tablets. This means we can offer customers a range of fill sizes in multiples of 15 – 60, 90, and 120 tablets – without needing to conduct more stability examinations. If, however, such tablets were in high-density polyethylene pots, we would need stability data on each and every fill size – a labour intensive process and, in our opinion, a waste of valuable resources.
Of course, another benefit of using blister packs is their weight. Since they're incredibly light – compared to materials like glass – they can save a significant amount of energy in the transportation process. Lighter products mean vehicles utilise less fuel, emit fewer greenhouse gases in transit, and have a smaller carbon footprint as a result. This saves our customers money, too.
Blister packaging also lends itself to unit dosing, which some consumers find more convenient. They’re portable, easy-to-open, and a practical alternative for those who have difficulty with glass bottles. Better still, they can be used discreetly if needed.
Admittedly, the combination of plastic and aluminium doesn't render blister packs entirely recycling-friendly at home. However, you can recycle your empty blister packets through The Medicine Packet Recycling Programme. Simply find the nearest participating Superdrug pharmacy or local pharmacy and drop off your empty blister packs during their opening hours.
You can learn more about the recycling programme and participating locations here.
Lastly, it's worth mentioning that our blister packs are fully compliant with EU regulations on plastic materials interacting with foodstuffs.
