If the bag doesn't hold the vacuum, it could be defective, so try selecting another bag and wrap paper around any sharp edges within the bag. Also, leaks along the welding seam could be the reason because of creases, crumbs, grease or liquids. In this case, open the bag again and clean the upper internal part of the bag. Remove any foreign matter that might be on the welding bar before sealing.
