Pharmaceutical Grade Oriented Polypropylene Paper Aluminum Foil Polyethylene Composite Bags (OPP/Paper/AL/PE)
Description
Pharmaceutical-Grade Heterogeneous Composite Protective Bags utilize a GMP-compliant four-layer structure of OPP/specialized composite paper substrate/aluminum foil (AL)/PE. This design combines the paper substrate’s cushioning properties and enhanced tear resistance, the aluminum foil’s absolute light-blocking and oxygen-barrier properties, and the inert inner seal of the PE layer, providing comprehensive physical and chemical barrier protection throughout the entire product lifecycle.
