How Does an Aluminum Foil Sealing Machine Work?
Aluminum foil sealing machines use advanced technology to create airtight seals, ensuring product safety and longevity. The most common type—induction sealing—works in three key steps:
1. Induction Heating Process
The machine generates a high-frequency electromagnetic field (typically 1–5 MHz) through a sealing head.
When an aluminum foil liner (with a heat-seal layer) is placed on the container opening, the electromagnetic field induces eddy currents in the aluminum layer.
This rapidly heats the foil (up to 180–220°C in seconds), melting the polymer coating beneath.
2. Pressure Application
The machine applies slight pressure (either automatically or manually) to bond the melted polymer layer to the container’s rim.
Once cooled, the foil adheres permanently, creating an airtight and leak-proof seal.
3. Tamper-Evident Protection
After sealing, consumers must peel or puncture the foil to open the container, providing visible proof of tampering.
This process ensures no direct contact between the sealer and the container, making it ideal for sterile environments like pharmaceuticals and food packaging.
