How Induction seal are Sealed?

Heat induction sealing films are typically used in the sealing process of containers to maintain product quality and freshness. The sealing process involves an electromagnetic induction sealing machine, which uses non-contact heating technology to seal containers. Below is an overview of the sealing process with heat induction sealing films, the working principle of the sealing machine, and precautions to be taken during its use:
Sealing Process:
Place the container with the product on the conveyor belt.
The sealing area of the container is automatically fed between two sealing bands and enters the heating zone.
The heating block transfers heat to the sealing area through the sealing bands, causing the film to heat and soften.
After passing through the cooling zone, the temperature of the film surface appropriately decreases.
By rolling through the embossing wheel or printing wheel, the upper and lower plastic films of the sealing area are bonded together and pressed to form a mesh pattern or printed logo.
Guide rubber bands and the conveyor belt transport the sealed packaging bag out of the machine, completing the sealing operation.
Working Principle of the Sealing Machine: The working principle of the electromagnetic induction sealing machine is based on electromagnetic induction. It allows the container’s lid to have a heat-seal composite aluminum foil for sealing. When electromagnetic waves pass through a metal object, they form an induced current in the object, generating heat, causing the object to be heated and melted. Thus, the sealing film is sealed by the electromagnetic field acting on the conductive carbonized aluminum foil material’s heat coil, allowing heat to be transferred to the adhesive layer contained in the sealing film through electromagnetic induction, achieving a fast and reliable sealing effect.
Precautions:
Not suitable for metal containers and metal caps, do not place on a metal surface and press the start button, to avoid damaging the machine.
Before use, the induction aviation plug must be inserted and the screws locked.
Use a single-phase three-wire power cord and ensure to use a single-phase three-wire power socket. The workplace floor must be dry to maintain insulation.
The equipment has an automatic over-temperature protection function. When the temperature inside the machine is too high, turn off the main power switch and wait for the machine to cool down before continuing work.
During operation, check whether the surface of the induction head is overheated. If it is found to be hot to the touch, stop heating and wait for it to cool down before continuing work.
The equipment must not be subjected to impact, heavy pressure, or moisture during transportation, storage, and use.
The information provided off the sealing process with heat induction sealing films, the working principle of the sealing machine, and the precautions to be taken during its use. During the operation process, ensure to follow all safety guidelines and the manufacturer’s instructions to ensure a smooth sealing process. If there are any doubts, it is recommended to consult the equipment manufacturer or a professional.
