Laser marking of aluminum coated film packaging bags (laser marking of tear lines)

Aluminum coating film evaporates high purity (1100~1200鈩? into gas through vacuum aluminum coating process, and then when the plastic film passes through the vacuum evaporation chamber, the gas aluminum molecules are precipitated onto the surface of the plastic film, forming a bright metallic film. Aluminum coating film is a composite flexible packaging material, which uses a special process to coat the surface of the plastic film with an extremely thin layer of metal aluminum. The commonly used processing method is vacuum aluminum coating method, that is, under high vacuum state, metal aluminum melts and evaporates at high temperature, so that aluminum vapor is precipitated on the surface of the plastic film, giving the surface of the plastic film a metallic luster. Because it not only has the characteristics of plastic film, but also has the characteristics of metal, it is a cheap, beautiful, excellent performance and practical packaging material.

Easy-tear line laser technology cuts dotted lines according to the needs of flexible packaging bags. The processing method is to use the beam generated by the laser to evenly cut a thin line only a few microns deep at the designed easy-tear line. This line destroys the outer packaging of the composite film and retains the inner packaging, which does not destroy the packaging function and causes the bag mouth to tear regularly during the tearing process. The equipment has an automatic positioning function! It can be used in various OPP, plastic, aluminum foil, anti-static/shielding bags, vacuum bags, aluminum foil masks, pet coarse grain bags, 25KG plastic granule paper aluminum-plastic composite bags, microporous vacuum bags, building materials packaging bags, moisture-proof bags, sealing films and other fields.

Most of the commodity packaging on the market is equipped with an easy-tear line to improve the use experience. What is an easy-tear line? Simply put, it is a pressure line that is convenient for consumers or users to tear, just like the dotted line we see in documents. Many paper and plastic bags on the market have such an easy-tear line. Generally speaking, the easy-tear line uses a dotted line cutting roller or a dotted line cutting, and the trademark generally uses a dot knife to cut the dotted line, but the processing effect is not particularly good, and many companies will choose to use an easy-tear line laser marking machine.
