ENOXITE\u00ae BARRIER provides an excellent oxygen barrier performance, particularly in low-moisture environments. For example, in a 50-micron LDPE coextrusion structure, a 5-micron layer of ENOXITE\u00ae E20 can achieve an OTR of 0.6 cc\/m2\u22c5day at 0% RH and 23\u00b0C.<\/p><\/span>\t\t\t\t\t\t\t\t\t<\/span>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t

ENOXITE BARRIER grades are compatible for use in multilayer structures with conventional polymers such as PP, PE, PS, PET, PA, as well as with biopolymers. In fact, a tie layer is not required when it is combined with biopolymers.
