How do we test the packaging?

The safety of children is paramount, so our child-resistant design experts are constantly innovating to create market-leading solutions. Our testing strategy is second to none and has helped brands from around the world to make their healthcare and pharmaceutical packaging totally safe for all. Our process ensures that we cover child-resistant packaging testing requirements. The testing stages include:

Child testing:

Panels of children aged 42 to 51 months are given a sample of the packaging for two five-minute test periods, one before and one after a demonstration by a member of the DiD team. Their approach to opening it is closely monitored and we ensure that different methods are used, such as using their hands, teeth, shaking the packaging and hitting it against hard surfaces. 80% of the children must fail to open the packaging for it to qualify as child-resistant.

Senior-friendly testing:

Child-resistant packs also need to be tested by senior adults to check that they can be opened without causing confusion, frustration and discomfort. After familiarisation, 90% of a sample of 100 adults aged 50 to 70 must be able to open and reclose the pack within one minute. This ensures that the style of packaging is safe for children whilst accessible to the elderly. We ensure that a vigorous child-resistant senior-friendly testing strategy in place.

Blister packaging:

This is tested to a different protocol to reclosable packaging and access to the product is evaluated according to its toxicity. For low risk products, up to 8 extractions can be made before the pack fails, whereas for high toxicity a single extraction could constitute a fail.

Constantly innovating to create a safer world

Upgrade your existing ranges

If you already have a product range and feel that its child-resistant design could be improved, you definitely need to have a chat with our experts. It’s absolutely imperative that any kind of healthcare or pharmaceutical product is entirely childproof, which is becoming increasingly difficult to achieve due to discrepancies in the wider system and the threat of illegal tampering.

By working with DiD, you know that your packaging has been developed and engineered by child safety packaging experts working to the latest standards, simultaneously applying vast ingenuity to go above and beyond. The outcome is integrated safety measures and sophisticated anti-tampering technology that place you firmly at the top of your industry.
