Heat Shrink Bands Seal Media Bottles

The heat-shrink bands found on Nalgene PETG (polyethylene terephthalate copolymer) Square Media Bottles are now offered separately for customers that perform liquid fill operations. End users apply the recommended application torque, and then the band is easily placed over the closure and heated to yield a secure containment of contents. When applied correctly, the bottles may not be opened without breaking the shrink-band. A broken shrink-band indicates that product integrity has been compromised. The bands are made of polyvinyl chloride (PVC) and can be gamma irradiated. They are compatible with the company’s 30, 60, 125, 250, 500 and 650 ml and 1 and 2 L PETG Square Media Bottles and HDPE closures. The shrink bands include a perforated tear strip enabling easy removal when desired. Torque wrench and torque fittings are also available.
