Czechs are known around the world for a number of inventions, such as soft
contact lenses or the Semtex plastic explosive. But not many know that they
also invented the so-called síťovka or net bag, which was a predecessor
of the widely used plastic bags. Czech Radio paid a visit to a Prague-based
company, called Czech Net Bag, which has been trying to revive the nearly
hundred-year-old product and bring it back into fashion.
