Need a tamper-evident seal? Try heat induction seals (HIS)

need-a-tamper-evident-seal-try-heat-induction-seals-his<p>Induction sealing, otherwise known as cap sealing, is a non-contact method of heating a metallic disk to hermetically seal (airtight seal) the top of plastic and glass containers.</p> <p><b>Step 1:</b> Apply the cap to the container. The liner usually comes already placed inside the cap.</p> <p><b>Step 2: </b>Heat. The container passes under an induction coil, causing the aluminum foil liner to heat. The heat melts the wax in the liner, which absorbs into the liner&#8217;s pulp backing and releases the foil from the cap. The polymer film also heats and flows onto the landing (lip) of the container. When cooled, the polymer creates a bond with the container resulting in a hermetically sealed product. Neither the container nor its contents are affected, and this all happens in a matter of seconds.</p> <p>So easy. So fast, and so tamper evident.</p>
