Cardinal’s self-seal and heat-seal paper sterilization pouches address the three primary requirements for a peel pouch: breathability, sterile barrier and indication of processing. These pouches combine a fracture-resistant film and a high-strength surgical-grade paper, which provide adequate breathability and required sterile barrier. These pouches also feature a peelable low-lint design. Dual chemical indicators visually identify those packages that have been exposed to either steam or EO sterilization. Self-seal pouches have extra-strength adhesive for sealing.
