How do you identify a predominantly plastic composite packaging, where two or more polymers are foreseen? For example a packaging consisting of 30% PET + 20% aluminum + 50% LDPE?

A pack made up of this way is a packaging consisting mainly of plastic with aluminum. For the identification of the material, the prevailing C / polymer + number associated with the plastic and aluminum coupling must be provided, i.e. 90 (as per decision 129/97 / EC). Therefore the coding is C / LDPE 90.
