High-temperature performance requirements are examined for hot-fill, retort, autoclave, and ovenable packaging. Coextrudable barrier resins and tie layer resins are evaluated for processability, and the benefits of low- and high-moisture barriers are compared in composites using moisture-sensitive oxygen barrier resins. Optimum barrier composite structures are defined and evaluated. Keywords: coextrusion, barrier composite, oxygen permeation, moisture vapor transmission, structural layer, moisture sensitivity, tie layers, barrier resins, hot fill, retort, autoclave, heat seal, flexible packaging Paper ID: STP18323S Committee/Subcommittee: F02.30 DOI: 10.1520/STP18323S ASTM International is a member of CrossRef. | ||
