Pouch conveyor belt system having a pouch conveyor belt with a conveyor belt body, preferably an elastomer conveyor belt body, which is designed to hold a conveyed material in the interior of the closed pouch conveyor belt, wherein the conveyor belt body has a first conveyor belt edge and a second conveyor belt edge, wherein the conveyor belt body has at least one sensor element, wherein the at least one sensor element is arranged in the first conveyor belt edge and/or in the second conveyor belt edge, wherein the conveyor belt body has an elastomer material or consists of an elastomer material in which, at least in portions, a reinforcing member and/or a tension member is embedded in the region of the first conveyor belt edge and/or the second conveyor belt edge, wherein the at least one sensor element is arranged between the reinforcing member and/or between the tension member and an outside of the conveyor belt edge (11, 12) which is configured to face a roller of the pouch conveyor belt system, having a plurality of rollers for guiding the pouch conveyor belt, having at least one transmitter unit which is designed to transmit data wirelessly to at least the sensor element of the pouch conveyor belt, and/or having at least one receiver unit, which is designed to receive data wirelessly from at least the sensor element of the pouch conveyor belt, characterized in that the at least one sensor element is designed to detect at least the temperature of the conveyor belt body at the location of the sensor element, wherein at least one roller, preferably a plurality of rollers, has a roller tensioning unit, which is designed to move at least one roller relative to the pouch conveyor belt in a movement direction of the roller tensioning unit and as a result to press on the pouch conveyor belt, wherein the pouch conveyor belt system is designed to control and/or to regulate the pressure of the roller tensioning unit on the pouch conveyor belt as a function of a temperature and/or as a function of a pressure and/or as a function of an identification code of the at least one sensor element of the pouch conveyor belt. having a pouch conveyor belt with a
