FAQ - Frequently asked questions

What materials are the blisters made of?

Is blister packaging environmentally friendly?

Increasingly, recycled materials (e.g. R-PET) are being used for the production of blisters. The recyclability of the finished packaging depends on local segregation systems. The need to separate the plastic from the paper can be a problem, but more and more mono-material solutions are emerging on the market to facilitate this process.

Folded blisters allow the carton to be easily ejected without destroying the packaging, which is useful when the customer wants to see the product up close before buying.
