(Induction sealing technology)
Induction Cap sealing system is non contact sealing one using a high frequency to bond to a container.
(Induction sealing process)
Induction sealing is to prevent leakage of contents from plastic and glass bottle. The cap is supplied with foil liner inserted, and the bottle is filled and capped in packaging operation. The capped bottle passes under the sealing head at speed up 200 feet. A high frequency induced by sealing head heats only the foil liner, penetrate the cap and heat foil layer rapidly melting a polymer coating which forms a hermetic seal with the lip of bottle.
(The advantage of Induction sealing)
- It shows tamper evidence
- Prevent leak of product during handling and storage
- Provides a good oxygen barrier
- Improving shelf life of products
- Enhance customer confidence
(Induction foil seal liner)
Induction foil liner is a material sealed by non-contact heating process that accomplishes the hermetic sealing of container with closure that includes a heat sealable foil laminate inside of the closure. It is composed of a layer of pulpboard or foam, a layer of wax, aluminum foil and a layer of heat sealable polymer that is adaptable with bottle material. There are basically two kind of the type of innerseal, One is One(1) piece innerseal, the other is Two(2) piece innerseal.
(One piece innerseal)
It have a function the same as the two piece innerseal, but nothing is left inside of cap after opened. There are various combinations of innerseal material like two piece innerseal, some are foam backed and some paper backed. It also can be custom printed with a customer's logo or trademark, or can contain some type of message, such as, " sealed for freshness." It can be welded and have to be destroyed, to be removed, or it may be peelable for easy removal.
(Two piece innerseal)
This type of innerseal, which, leaves a pulpboard or foam liner inside cap after opened, It is normally used when a product to be required to leave some type of secondary seal in the cap, to prevent leakage, after induction seal has been removed. It also can be custom printed with customer' logo, trademark like one piece liner.
