Latest Induction Cap Sealing Technology, to create alternative, airtight, hermetic seals on the necks of containers. The process can produce significant cost savings in the Packaging Process. The seal is strong, flexible & yet easy to remove and provides protection against contamination. Induction heating allows heat sensitive products such as creams, petroleum products, pesticides etc. which would normally gets spoiled or catch fire on normal heat sealing to be sealed. The sealing takes place without any direct contact which allows full potential of the filling plant to be utilized.
The process of Induction Cap Sealing is based on the principle that a conductive material i.e. Al Foil heats up on exposure to high frequency magnetic field generated by an Induction Unit. This is a non contact process without direct heat transfer. Due to this, the sealable closure liner can be placed in the cap by the manufacturer. The Wad consists of a board packing material, a wax layer, Aluminum foil and a sealable film. The screw cap combination passes through the induction unit after closure of the container. When the container is under the induction head, heat is developed into the Aluminum layer. The wax layer starts to melt and penetrates into the board layer. The Sealing layer also melts & forms a tight seal against the lip of container. The necessary pressure is provided by the liner/screw cap combination. On opening the container, the board remains inside the cap and serves as a seal on further use, whereas the aluminium foil is permanently sealed on the rim of the mouth of container.
ADVANTAGES OF INDUCTION CAP SEALING:
Tamper Proof: It is not possible, from production to the Consumer that the content of the product be manipulated without being clearly noticed.
Product Freshness: The taste and aroma of the product remains intact due to the hermetic seal.
Protection against Leakage: There is no spillage or loss of contents of the product.
Sales Promotion: The foil on the inside can be used for advertising or promotional purposes.
Maximum Filling Speeds: The sealing takes place without any direct contact which allows full potential of the filling plant to be utilized.
Minimum Effort: The wad is put in the cap by the manufacturers. Thus the filling line requires only the Induction Cap Sealing equipment to be installed.
Indirect Heating: Induction heating allows heat sensitive products such as creams, petroleum product, pesticides etc. to be sealed faster and safely than direct heating which would normally spoil or catch fire.
IGBT Technology: IGBT's are more reliable and efficient at higher line speeds.
SEMI AUTOMATIC TABLE TOP: 4 To 5 Containers per Minute.
Portable Induction Sealing System for very small production units. It can seal from 10mm up to 53mm and can give 4 to 5 containers per minute. This system does not require water cooling as it is equipped with an inbuilt timer. There are separate Induction Head available for various diameters ranges.
