[Class 140] Cartons or other packages are sealed or reinforced with a tape coated with a mixture of a water-soluble protein type glue blended with a substantial but smaller proportion of asphalt or substance of a bituminous nature, the tape being wetted with a solution of a dialdehyde, preferably glyoxal, before application to the carton. The tape may have a backing of fabric, strong paper such as Kraft, or plied paper stock reinforced by fibres, fabric or threads, which backing may be coated with a mixture of bone and hide glue dissolved in water and emulsified with the asphalt, or emulsified with roof or building tar, pine tar pitch or Burgundy pitch. The coated tape is dried. In use the tape is wetted with the aqueous dialdehyde and applied to the carton, which will then withstand exposure to humidity and water.
