In order to properly package food with a Mylar Pouch and Oxygen Absorber, it is important to achieve a good seal on your pouch. This 12” impulse sealer provides a great 5mm wide seal in order to assure a tight seal. Other sealers are cheaper but don’t offer a wide enough seal (5mm). It is easy to use and convenient as there is no warm-up time for sealing. This sealer is not only useful for sealing Mylar Pouches, but can be used to seal other types of plastic bags.
