First experience on the then new article now known as PVC.


Acquisition of the first calander to produce PVC sheeting, for raincoats and tablecloths’ manufacture.


History was made when installing the first printing machine for plastic sheeting. This was a decisive step into a field that was unknown until then, that of the decorative plastics.


Adreta decides to implant its activity abroad and founded Adreta Plásticos in Portugal.


Factory unit in Hamburg was sold, and Adreta Plásticos being no longer a branch, became an independent company.

since 1958

We’ve settled here back in 1958, arriving by hand of our preceding congener in Hamburg, Germany, bearing then already more than three decades’ history in the making of multi-use waterproof sheetings.

At the time of its original foundation by Richard Weber in 1925, the company produced artificial leather and gutta-percha film, both types precursors of the now existing plastic sheetings that came to replace them during the following decade, owing to the technological
developments as well as the sourcing for cheaper materials.

In these more than thirty years preceding the company’s establishment in Portugal it was accounted for its contribution in the research and development of plastic PVC sheeting production, for introducing new techniques and finding new uses, highlighting the creation of printed sheetings, introducing a whole new concept of decorative plastics in 1948.

Ten years later ADRETA PLÁSTICOS comes to establish in Portugal as a branch of its German motherhouse from which it would emancipate in 1965 by assignment of the first, inheriting the name and the epithet (from Latin ad directus and later from Occitan adret, designating rectitude/accuracy/prime) under which we have met the last sixty years’ challenges and propose to face the next – making well done pretty (*) things:
