The difference between pressure-sensitive gaskets and aluminum foil gaskets.

1. Pressure-sensitive pads are widely used as seal materials for bottle openings at present. Due to their pressure sealing properties, they are easy to operate and cost-effective. Pressure-sensitive pads are composed of PS foam pads coated with pressure-sensitive adhesive, generally known as "pressure-sensitive pads." They are single-piece and without aluminum foil. They provide sealing functions at normal temperature by relying on the pressure of the bottle cap. They are used in glass bottles, metal bottles, and plastic bottles (the effect is better for solid, dry food or drugs inside the bottle).

2. The electromagnetic induction aluminum foil sealing pad is composed of paperboard, aluminum foil, adhesive, sealing film, etc. It is placed under the inductor by the general non-contact heating method of the electromagnetic induction sealing machine. Through electromagnetic induction, high temperature is generated instantly. After the pad paper is heated, the aluminum foil sealing layer seals the bottle mouth, achieving the effect of sealing the fragrance to prevent leakage. In addition, it also has anti-counterfeiting and anti-theft properties.
