Made from two films, Mitos DuraPure bags offer a high-purity contact surface with a durable exterior to protect your product. The inner film is virgin low-density polyethylene (LDPE). The outer film is a multifunctional co-extrusion of linear low-density polyethylene (LLDPE), ethylene vinyl alcohol (EVOH) and ethylene vinyl acetate (EVA). The outer film provides a secondary high-purity surface (LLDPE), a permeation barrier (EVOH), and puncture and tear resistance (EVA). DuraPure bags are USP Class VI and are animal free.
