What or who is Fefco?

FEFCO is the European Federation of Corrugated Board Manufacturers and is representing the interests of that industry, both technical and economic level. 

They came up with a system to substitute long and complicated verbal descriptions of  fibreboard case and packaging constructions with simple symbols internationally understood by all, regardless of language and other differences. In other words, if you ask us if it is possible to create a Fefco-0227, we know what box you are referring to. Their catalog can be found here.
