Lid adhesive eliminates contamination risk

. Compared with water-based coatings, hot-melt adhesive coatings ensure anchorage and eliminate the risk of residue depositing on the medical device. Manufactured by Oliver Products (Grand Rapids, MI; 800/253-3893), NP34 is a nontoxic heat-sealable adhesive coating that works with DuPont's 1073B Tyvek lidding material. This adhesive-application combination seals well to silicon-coated PETG trays, and provides peelable seals with uniform adhesive transfer on most rigid plastics. NP34/1073B features cold shock resistance to –10°C and a high coating weight. It is appropriate for EtO and radiation sterilization.
