When a company thinks about the type of packaging sealing it needs for its products, it analyses the pros and cons of induction and conduction sealing methods. As experts in induction container sealing, Cap Sealing Products, S.L. recommends this method due to the advantages it presents for the consumer, the manufacturer and the product itself.
The following are the advantages of induction sealing:
Our induction sealing machines ensure a sealing system without contact with the container. During the packaging process, the container can already have the lid once filled and can be sealed by induction, without any added contact, since the pressure of the liner against the mouth is made by the lid. This process results in a cleaner container seal.
The conduction heat sealer, however, has to “iron” the sealing material on the container mouth, which implies a contact with it.
Induction container sealing can be carried out without stopping the packaging circuit. The induction sealing machine adapts perfectly to any conveyor belt speed and does not require it to stop.
In contrast, the conduction heat sealer requires each container to stop to perform the sealing.
The induction sealer can seal various types of jars with different container mouth diameters in a range from 20 mm to 80 mm or even up to 130 mm. Conversely, the conduction heat sealer can only seal one diameter: the one specific to the jar that was initially planned. If there is a subsequent change of jar, the packer must buy another heat-sealing machine.
In conclusion, induction sealing is a more versatile system with a greater capacity to adapt to the changing needs of the company.
