Although there is a wide range of closures available ,the conventional bore sealing has, to date, been the most widely used method of sealing containers .Bore seals are inexpensive to manufacture and are relatively easy to fit. However, bore seals are do not form hermetic , flexible or even reliable seals- they leak. There are three types of closures available, which are either inserted into the neck of or form a combination of two. The effectiveness of this seal can be affected by temperature, natural relaxation & mechanical properties, all of which will cause seal to leak, especially in transit.

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 hermatic 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 utilsed.
• 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 , petroluem 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 efficent at higher line speeds.
