Principle

Induction cap sealing is a non-contact heating process that accomplishes the hermetic sealing of a bottle with a cap which includes a heat-sealable foil liner. When the cap / liner is placed on bottle opening and this bottle passes under an induction coil which emits a varying electromagnetic field. In the meantime, the conductive aluminum foil liner begins to heat the required temperature. The content of bottle is not inducted by electro-magnetic field, but the seal film of foil liner is heated and attached onto the lip of bottle by the induction coil. After cooled, the seal film creates a bond with the bottle resulting in a sealed product.

Application

Application for non-metal material glass containers or plastic bottles, such as ABS, PE(HDPE, LDPE), PET, PP, PS, PVC…etc. Specially applicable for foods, soft drinks, beverage, pharmaceutical and chemical industries.
