Carbon dioxide permeability

The permeance of carbon dioxide, oxygen, nitrogen, and air through commercial polymers based on polyethylene (PE), biaxially oriented polypropylene (BOPP), and polyamide (PA) used for food packaging is reported. The influence of temperature (from 10 to 60 C) and crease stress cycles (30, 50, 70, and 110) on gas permeance is also analyzed.
