Common faults in heating and sealing of food vacuum packaging machines

1. The sealing can't be absolutely sealed
Check if the heating sealing strip is heating commonly and if the temperature has reached the set value
Check if there are any overseas items connected to the floor of the heating sealing strip that have an effect on the sealing
Adjust heating time and stress to make certain enough fusion
Check if the sealing rubber strip is worn or deformed, and update it in a well timed manner
2. White stripes seem on the sealing area
Heating temperature too excessive, inflicting nearby immoderate melting of plastic film
Lower the sealing temperature and shorten the heating time appropriately
Check for aging, peculiar heating of heating elements
3. Explosive holes seem on the sealing area
Excessive heating time results in immoderate melting of the plastic film
Reduce heating temperature and time, and manipulate inside the proper range
Check if the sealing stress is simply too excessive and decrease the stress appropriately
4. Wrinkles seem on the sealing area
Uneven feeding of packaging baggage and inadequate anxiety
Adjust the feeding attitude and anxiety of the packaging bag to make certain clean entry. Check whether or not the additives which include the manual curler and clamping curler are worn or loose
5. Insufficient sealing strength!
Improper putting of heating time and temperature, failure to obtain enough fusion. Increase heating time and temperature appropriately, enhance sealing strength, test if the sealing strip is worn or deformed, and update it in a well timed manner
