The E-250 Automatic L Bar Sealer style shrink wrap machine is engineered for efficiency with logic and precision. As product is fed onto the conveyor, photo-electric eyes measure and advance it to the centerfolded shrink wrap film and heat sealing area. To prevent the next package from entering during the shrink sealing cycle, the belt advance is temporarily deactivated. When the heat sealing jaw opens, the advance is reactivated and the shrink wrapped product is discharged into the shrink tunnel. It's logical. It's precise. It's efficient.
