The E-250A Automatic L-Bar Sealer shrink wrap machine is engineered for flexibility with logic and precision. As product is fed onto the conveyor, electric eyes measure and advance it into the centerfolded film and begin the sealing cycle. To prevent the next package from entering during the sealing area, the belt advance is temporarily deactivated (intermittent motion). When the heat sealing jaw opens, the product advance is reactivated and the shrink wrapped product is discharged into the shrink tunnel. Product recipes will control all these functions once they are set.
