Aluminum foil sealing film may encounter some common problems during use, mainly in industrial induction sealing processes. These issues are often related to improper matching of equipment, materials, containers, and process parameters. 

Next, Leadtra will use several articles to reveal the most common problems, their causes, and solutions. Today, let's take a look at problem one - the sealing film cannot stick or seal firmly. 

Phenomenon: The sealing film can be easily peeled off completely, with no residue at the bottle mouth and no melting marks on the heat sealing layer. 

Possible reasons: 

Insufficient device power/time: the most common reason. The output power of the induction sealing machine is too low or the heating time is too short, resulting in insufficient heat to melt the heat sealing adhesive. 

Mismatch of film material: The heat sealing layer material of the sealing film does not match the bottle mouth material (such as PP, PE, PET, glass), and the melting point does not match. 

Bottle mouth problem: The bottle mouth has moisture, oil stains, dust, or release agents that hinder bonding; Unreasonable bottle mouth design (such as unevenness, thread interference). 

Excessive sensing distance: The distance (air gap) between the sensing head and the top of the bottle cap is too far, resulting in insufficient magnetic field strength. 

Solution: 

Gradually increase equipment power or extend sealing time. 

Confirm the material of the bottle mouth and request matching sealing film from the supplier. 

Ensure that the bottle mouth is clean, dry, and free from contamination. 

Adjust the height of the sensor head to the optimal distance.
