Suited for applications in food and beverage packaging, transport, and storage, sensory-sensitive thermoplastic elastomers (TPEs) include specialty compounds and formulations that can be used to manage permeation of CO2, water vapor, and oxygen in addition to improving sealing properties. Grades meet most food and beverage contact standards of FDA, EU, and GB; are fully recyclable; and provide low extractables, organoleptic neutrality, and clarity.
