This sealing machine based on the principle of electromagnetism induced, it produces a high speed mutual changing electric field on the aluminum foil after connecting electrical power, this electric field makes the foil molecule abrading fiercely and creates a high instantaneous changing temperature about 140~120。C and makes the glue on the foil stick on the bottle, at the same time, the weak glue layer between foil and paper board falling down, the foil and paper board separated and packaging finished. the effect is very perfect and the items after packaging have the ability of humidity proof, guard against theft, guard against fake and anti-oxidation. The container’s element can be PE, PP, PET, PS,ABS, glass and so on, metal bottle forbidden(we can supply various kinds of aluminum foil).
