    • A
      Anthony ClarkeAug 7, 2025
      If your PolyScience Kitchen Appliances vacuum sealer isn't pulling a complete vacuum, first increase the Vacuum Level and/or Seal Time as required. Ensure the edge of the bag is correctly positioned across the seal bar, and the bottom of the bag mouth is properly clamped. Reposition the bag in the vacuum chamber if needed, smooth out any wrinkles along the seal bar, and check for gaps or flaws in the sealed end of the bag. Also, clean any crumbs or debris on the bag or seal bar.

      If your PolyScience Kitchen Appliances heat-sealed bag loses vacuum after being sealed, it could be due to a puncture. Cover any sharp edges with a paper towel and vacuum package in a new bag. Alternatively, it could be due to out-gassing. Open the bag and check for spoilage. If spoilage hasn't begun, consume immediately.

      Andrew HuntAug 20, 2025
      If your PolyScience Kitchen Appliances canisters are not vacuuming properly, ensure the external vacuum hose is fully inserted into the canister lid and securely attached to the vacuum hose port on the Chamber Vacuum Sealer. Allow at least 1 inch (2.5 cm) of space between the surface of the items in the canister and the lid. Also, check the canister, lid, and seal for any damage.
