Difference between pressure-sensitive pads and aluminum foil pads

1. Pressure-sensitive gaskets are widely used as sealing materials for bottle mouths. As they are pressure-sealing materials, they are easy to use and inexpensive. Pressure-sensitive gaskets consist of PS foam gaskets coated with pressure-sensitive adhesive; they are commonly referred to as “pressure-sensitive gaskets.” These are single-piece units without aluminum foil, and they provide sealing functionality through the pressure applied by the bottle cap at room temperature. They are used for glass bottles, metal bottles, and plastic bottles (especially when the contents are solid dry foods or medications).

2. The electromagnetic induction aluminum foil sealing gasket is composed of cardboard, aluminum foil, adhesive, and sealing film, forming an integrated unit. It is applied using an electromagnetic induction sealing machine that can heat non-contactly. Under the sensor, electromagnetic induction generates high heat instantaneously. After heating, the paper layer separates, and the aluminum foil sealing layer seals the bottle mouth, achieving a sealed, leak-proof effect. Additionally, it provides anti-counterfeiting and anti-theft features.
