Reasonable control of the processing conditions of a packaging material ensures the absence of material loss during this step, but above all the achievement of production rates ensures the economic viability of the technological step and its optimization in terms of environmental impacts.
However, process optimization also generates biases that should be known in order to anticipate their effects.
Excessive use of lubricants, antistatic additives, processing aids
Undesired effects: loss of adhesion of printing layers or complex layer delamination, high levels of overall or specific migration, organoleptic effects (particularly concerning antistatic additives).
