Nozzle type vacuum sealers, industrial vacuum sealers, poly bag sealers Retractable Nozzle vacuum sealers are the most versatile among the three types of vacuum sealers we carry. Ideal for vacuum/gas flush packaging. This type of vacuum sealer requires a compressor to operate, but some sealers are internally equipped for the convenience of the user. We carry vacuum sealers with sealing widths from 11" to 50" to cover a variety of applications. Many options such as stainless steel, double sealing jaws, single or double retractable nozzles, analog or digital controls, pneumatic or built in air compressor are available to suit the needs of the operator.
