Description

Technical Field

[0001] The invention relates to a forming device, in particular to a vacuum aluminum-plated film internal thread forming device. Background Art

[0002] Vacuum aluminum film is a kind of vacuum evaporation metal film. It is a process of melting and vaporizing aluminum under high vacuum conditions by heating with resistance, high frequency or electron beam, and attaching it to the surface of the film substrate to form a composite film. A very thin layer of metal aluminum is plated on the surface of plastic film or paper to become an aluminum film or aluminum paper. Compared with aluminum foil, it greatly reduces the amount of aluminum, saves energy and materials, and reduces costs. The thickness of composite aluminum foil is mostly 7-9um. It has excellent folding resistance and good toughness, rarely has pinholes and cracks, no bending and cracking, and improves the barrier properties of gas, water vapor, odor, light, etc. It has excellent metallic luster and a light reflectivity of up to 92%; and it can be treated with paint to form a colored film, and its decorative effect is beyond the reach of aluminum foil. Partial aluminum plating can be performed by shielding or elution to obtain any pattern or transparent window to see the contents of the package. The aluminum layer has good conductivity and can eliminate static electricity effects. Especially when packaging powder products, it will not contaminate the sealing part, ensuring the sealing performance of the package.
