We use Polypropylene extensively in everyday products as it is low cost and has some excellent mechanical properties such as good impact resistance, is flexible, has a low MVTR (Moisture Vapour Transmission Rate) and you can create living hinges within a moulding.

One disadvantage it has always had, is that optically transparent products could not be created, only translucent products.
However, a new additive has been developed that allows highly transparent injection moulded PP mouldings to be created, delivering clearer versions than standard PP. It will allow food, toiletry and cosmetic containers to be produced in a much clearer PP. It is FDA approved too.

If you have an application that could utilise this technology, contact Gm Design & Development for advice.
