Main Application:
This machine is mainly used for the sealing of plastic containers with inner aluminum cap foil. It can ensure materials in the bottle damp-proof and prevent to be imitated. It is mainly applied to the packaging lines of medicines, foodstuffs, chemicals, cultural goods, cosmetics, and light industries etc.

Operating principles:
As this machine adopts principle of electromagnetic induction, the goods in magnetic field can be sensitive to magnetism and heated up in a very short time. The surface of aluminum foil produces intense heat for an instant, and intense heat is conducted to the heat sealing so as to achieve airtight seal. Those containers made of polyethylene (PE), polypropylene (PP), polystyrene (PS), polyester (PE) and glass ceramics etc. Are applied to this kind of sealing.

Structural features:
This machine adopts intermediate frequency power supply, its active power output is great and outgoing current can be adjustable. It will stop automatically when there is no bottle in the specified position. The machine is characterized by special induction plate, wholly-shielded screen, short sticking time, high speed, easy operation, and stable capability. Besides, it owns auto shutdown functions, such as over-current, over-voltage and under-voltage protection etc. Integrated power amplifier is used on the circuit, which can ensure the stability of electric current. Uniformity of sealing is acquired after the process is finished. There is no way to appear false seam or yellowed aluminum foil on the basis of over heat. It also has function of automatic rejection to caps without aluminum foil, in which the machine can inspect and pick it out automatically. The accuracy of sealing is guaranteed
