摘要：Appropriate labeling and flexible packaging plays an important role on the today`s demands.There is diverse possibilities especially related to polymeric materials.Flexible packaging means to consider options such as OPP (Oriented Polypropylene),PVC (Polyvinyl Chloride),OPS (Oriented Polystyrene),PET (Polyethylene Terephthalate) or all kind of self-adhensive paper and foil types.Special highlight are the "Shrink Sleeve" labels that meet the most demanding market challenges.Its capabilities are beneficial.Laminated packaging materials are functional.Both constitute protection and packaging capacity.Coefficient of friction is the value that serves to meet the standard of how the flexible packaging material will glide and move on the packaging machine.This research is focused on the optimum quality of the packaging production process to meet all the preconditions for implementation of the semifinished product packaging and to avoid difficulties and possible stoppages on the packaging machine itself.
