The Role of OPP and CPP in Multi-Layer Packaging
OPP (Oriented Polypropylene) and CPP (Cast Polypropylene) are two of the most essential components in multi-layer packaging structures. While OPP stands out for its print quality and glossy surface, CPP enhances product safety with its puncture resistance and heat-sealing performance. The right combination of these two materials ensures both extended shelf life and a visually appealing appearance for food and industrial products.
