Testing conducted by third-party labs have shown how MPX2 Polybags can reduce the proliferation of E. coli bacteria and Staphylococcus aureus by 99.99% for 24 hours, while also effectively eliminating Asperigillus niger, which is one of the most common moulds found in consumer goods. MPX2 Polybags are sold in sealed packages, come in a variety of sizes, and are easy to use with the finished product simply inserted into the polybag at the time of final packing.
