Cap Sealing Machines
AM Ozonics Pvt Ltd offers Cap Sealing Machines. Induction sealing is a simple and reliable method of bottle sealing. It welds an aluminium foil seal across the bottle neck to: prevent product leakage; provide tamper evidence; improve product shelf life due to the excellent barrier properties of the foil and its airtight seal onto the container; and improve pack presentation and customer acceptance. Bottles are filled and capped with a cap fitted with an aluminium foil seal (wad) and then passed under the induction sealer. This transmits an electromagnetic field, somewhat similar to a microwave oven that heats the aluminium seal and bonds it to the container neck. The bottle is tilled at position and the cap, complete with aluminium foil seal, is applied at position; the capped bottle is then passed under the induction sealing machine which, causes the induction seal liner in the cap to heat up and bond to the container neck by position; when the bottle is later opened the aluminium foil liner is released from the cap and left in place across the bottle neck. Induction sealers transmit an electro magnetic field, which creates eddy currents in a metallic element, such as an aluminium foil induction inner seal, placed in the magnetic field. This current heats the aluminium foil seal and its plastic coating bonds to the container neck. Induction sealing machines comprise a power source, a sealing head or coil and a cooling system. Manual hand held units are available for laboratory or low volume work but high power automatic cap sealers are usually mounted above conveyorised production lines. Some induction sealers, especially older ones, are water cooled and have the power generator at floor level connected to the sealing head, mounted above the conveyor, by combined electrical and cooling cables.
