FAQ - Frequently asked questions
What materials are the blisters made of?
The most commonly used plastic for pocket formation is PET (polyethylene terephthalate) or PVC (polyvinyl chloride) film due to their rigidity and transparency. The closing layer is usually printed cardboard, aluminium foil (for medicines) or another plastic film.
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.
What is the main difference between a welded and folded blister?
The main difference lies in the method of closure and the level of security. Sealed blisters are permanently sealed, providing excellent protection against opening and theft. 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.
