Induction sealing is a non-contact method of sealing a container with a closure that includes a heat-sealable foil laminate. This process is widely used in the packaging industry to create a tamper-evident seal on bottles and jars.
Process[edit | edit source]
The induction sealing process involves the application of an electromagnetic field to the closure, which contains a foil layer. When the container passes under the induction coil, the electromagnetic field induces an electric current in the foil. This current generates heat, which melts the heat-sealable layer, bonding it to the container's rim.
Components[edit | edit source]
The key components of an induction sealing system include:
- Induction coil: Generates the electromagnetic field.
- Power supply: Provides the necessary energy to the coil.
- Foil seal: Consists of a layered structure with a heat-sealable film.
Applications[edit | edit source]
Induction sealing is commonly used in the food, pharmaceutical, and chemical industries. It provides a hermetic seal that prevents leakage and contamination, ensuring product integrity and safety.
Advantages[edit | edit source]
- Tamper evidence: Provides a visible indication of tampering.
- Leak prevention: Ensures a tight seal to prevent leaks.
- Extended shelf life: Protects contents from oxidation and moisture.
Limitations[edit | edit source]
- Material compatibility: Not all materials are suitable for induction sealing.
- Equipment cost: Initial setup can be expensive.
