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

Applicable to non-metal containers like plastic bottles, including materials such as ABS, PE(HDPE, LDPE), PET, PP, PS, PVC, etc. It is especially suitable for the food, soft drink, beverage, pharmaceutical, and chemical industries.

Options
