Lidding of DuPont™ Tyvek® is ideal for thermoformed trays and helps to protect high profile, heavyweight and/or fragile devices so that they maintain sterility and integrity until opened with a clean peel aseptic presentation. Up to eight times stronger than medical-grade papers of equal or greater basis weight, Tyvek® resists punctures—even from the irregular or sharp edges of many surgical devices.
