Continuous Induction Sealer


Induction sealers seal an aluminum laminated liner to the top (bunghole) of plastic containers and/or glass containers with flat threaded caps. This lining consists of several layers of materials typically one metallic layer over a thermoplastic layer. When the container is positioned next to an active induction head, one or more induction coils excite the metallic molecules of the metallic layer. This ultrahigh frequency vibration causes the metal layer to heat up, which in turn melts the thermoplastic layer of the lining causing it to fuse to the top of the container. This seal is hermetic and impermeable to gases. In effect the lining becomes part of the container. From this point on nothing enters or exits the container until the lining is punctured. For this reason induction sealers are used widely thought many industries. The process is extremely simple, and can be accurately repeated time after time.


Rotating Heating Head installation can be suitable for all kinds of bottles; No limit on cap size, bottle size, cap and bottle shape etc. Only one machine can seal all your botttles, save machine purchase costs.

The same model sealing heads, water tank and host can be replaced by each other; Save maintenance costs in near future

It is suitable for all shape of bottles and caps, especially for complicated-shape caps

Latest designed modular technology which ensure machine has good performance on anti-corrosion, moisture-proof, dustproof and anti-EMI and has longer working life
