Common Cap Liner Problems
In order to get a good hermetic seal, it's necessary for the foil innerseal (inside of the cap) to be in contact with the lip of the container and have consistent pressure around the circumference. This is accomplished by applying correct application torque to the cap. When the application torque is inconsistent, the result is inconsistent seals.
Operating Controls and Indicators
All units have some variation of the basic controls - status indicators, power output display, and 4-start/stop and up/down keys. The locations and additional functions vary by model.
Positioning your sealing head
Sealing head positioning is critical to successful sealing. The power of the electromagnetic field reduces by the square of the distance, meaning that if you double the distance between the seal and the head you only have 1/4 the sealing power.
Tips for checking induction seals
How do I know if I have a proper seal? Due to the wide variety of sealing materials available, particular adhesion properties will have to be determined by the customer. Generally, proper sealing can usually be determined by the following questions.
Understanding induction sealing
Induction sealing is a non-contact heating process that accomplishes the hermetic sealing of a container with a closure that includes a heat-sealable foil laminate. The typical induction innerseal begins as a multi-laminate liner inside a closure
