Possible cause and solution
When the sealing strip is overheated and melts the bag, lift
the cover and wait a few minutes until it cools down.
Check if the pressing seal is in correct position and not
damaged.
The sealing may be incomplete due to folds, crumbs, fat, or
moisture. Reopen the vacuum packing bag, clean the upper
part of its interior, remove all foreign objects from the sealing
strip, and repeat the sealing operation.
Check the bag for damages which may cause the vacuum
loss. Cover the sharp edges of the bag content with the
paper towel.
Reconnect the container cover to the device suction nozzle
with the hose (or the cover connector when required).
Leave at least 3 cm of space between the container content
and its upper edge.
When the liquid product starts to overflow during th vacuum
packing, it may result from insufficient cooling before
packing. Cool the product in the refrigerator, not in the room
temperature.

container edge and cover with the moistened cloth and
repeat the vacuum packing when required.

not damaged.
