Covema srl was a historic Italian company specializing in the design of plastic processing machinery, based in Milan, via Fontana 1.

In the meantime, exports to the Latin American markets began and Marco Terragni was asked during his missions abroad to produce in plastic various objects made so far of wood or paper or glass.

[5][6] Still at the RIAP at the beginning of the 1970s a group of researchers coordinated by Marco Terragni created a first pilot plant for the production of Cartonplast (PP alveolar sheets).

[7] At the company Corima at Cassano Magnago, Covema realized the specific development of multi-filament plants and systems to cover electric cables.
