A flexible smoke generator comprising smoke composition particles embedded in an elastomer, preferably a silicone rubber compound that is molded or extruded into a relatively thin layer. The smoke generator may further comprise flexible circuitry to provide a currency alarm pack having the flexibility and feel of a standard currency pack without an alarm. The smoke composition particles may contain a red dye and/or tear gas. The smoke composition particles have a preferred particle size range small enough to pass through a number (18) sieve and large enough not to pass through a number (40) sieve. The smoke generator may be provided with a film covering, such as polyurethane, which may provide sealing capability for sealing the smoke composition particles and/or tear gas within the elastomer. The smoke generator may contain embedded reinforcing fibers for additional strength. |
