Aluminum Foil for Bottle Caps, Color : Silver

With induction sealing, a foil liner is placed underneath the cap on a bottle or jar. A heating head from an induction sealing machine is then placed over the cap and non-contact heat is applied. This is completely non-contact, as contact heat would likely melt the cap and jar.
It helps to prevent the introduction of chemicals and microbes that could spoil the products and/or cause illnesses Aluminum foil does reflect heat, as well as light energy. Aluminum foil reflects about 95% of the infrared heat that hits its surface, essentially blocking heat transfer. Aluminum foil also blocks the flow of radiation, making it useful in preventing heat loss.
