Tamper Resistant Stretch Wrap

Stretch wrap film is increasingly being used to secure palletized cargo for shipment due to its low cost and ease of use with irregular loads. IST is proposing to develop a stretch wrap material that provides a visible means of tamper indication. This will be accomplished by impregnating the wrapping material with liquid tagging agents. These agents will remain clear while in the film in order to disguise their presence and permit visual inspection of the cargo. If the film is cut or punctured the liquid will be released. It will then react with the atmosphere to form a dye that stains the surround of the opening as well as the hands of the perpetrator. Both visible and UV fluorescent tagging agents are readily available. Which type is used will depend on whether or not it is desired that the perpetrator know that their actions have been detected. By indicating the location of possible tamper sites, as well as potential suspects, ISTs secure wrap technology will greatly improve supply chain security. This will be an invaluable tool for ensuring the safety of cargo coming into the country or going out to our forces abroad.
