What it is

A pressure sensitive foam liner that seals without heat. Just screw the cap tight, and the adhesive activates. No induction sealer. No heat gun. No equipment needed.
The foam liner is made of PS foam coated with a torque-activated pressure sensitive adhesive. It bonds to the bottle rim through the pressure of the cap. Once sealed, it stays on the container when the cap is removed.
This one comes with red printing. You can also customize the print-your logo, your text, your color.
