With its flexible settings, the Catler VS 8010 can be tailored to the individual ingredient for the best results. Are you sealing fresh salmon or maybe a steak? Choose NORMAL speed and MOIST food to ensure a firm and dry seal. Do you have dried herbs with woody stems you'd like to keep fresh? Choose GENTLE speed and DRY food to prevent the stems from puncturing the bag. You can also choose SEAL only to make your own custom-size vacuum bags from rolls.
