    Yes. The SD-657 case sealer comes standard with safety glass panels that help protect operators while still providing a clear view of the sealing process. For added safety, the machine is equipped with door safety interlocks that automatically shut down the machine if a safety door is opened during operation. This helps protect operators during use while allowing safe access for maintenance and adjustments when needed. 


    The SD-657 Hot Melt Case Sealer is an automatic carton sealing machine that uses hot melt adhesive instead of tape to seal corrugated cases. By replacing tape with glue, the SD-657 creates a clean, secure seal while reducing tape consumption and improving package appearance. The machine automatically folds the top flaps, applies hot melt adhesive, and closes the case in a single operation for efficient, high-volume packaging.
