How is the film laser drilled?

Laser drilling, is to use the beam generated by the laser to evenly cut the designed solid line, dotted line, wavy line, and easy-tear line into a thin line with a depth of only a few microns. Due to the advantages of laser in focusing, the focus point can be as small as the order of sub-micron, so it has more advantages in micro-processing of materials, and the depth of cutting, marking, scribing, and punching can be controlled. Even at low pulse energy levels, higher energy density can be obtained, and materials can be processed effectively. Laser equipment can be installed on slitting machines or rewinding machines to cut, scribing, punch, and layer cut on flexible packaging materials such as OPP, BOPP, PE, PE, PET (polyester), aluminum foil, paper, etc.
The advantages of the laser punching machine method are as follows:
1. The punching accuracy is high, the spray hole is smoother, there are no burrs and burrs around, and it is more uniform;
2. It adopts microcomputer control, and the hole type and size can be changed freely, which is more flexible to use;
3. Avoid the trouble of replacing the punching mold and silicone plate, reduce costs and improve production efficiency;

There are also some packaging bags with strict requirements that need to be breathable and waterproof. Do you find it hard to believe that there are holes that are both waterproof and breathable? Laisai Laser can tell you very responsibly that this is achievable. Guangzhou Laisai Laser thin film air hole laser drilling machine, as a special equipment for ultra-fine air holes, can achieve a small aperture of 0.1-0.3mm and a small hole spacing of 0.3mm. It is waterproof and breathable, with uniform holes, any direction and any shape, and fast speed. It can be used in conjunction with traditional equipment cutting machines, bag making machines, handheld machines, etc.
Seed packaging bags usually have air holes to ensure the breathing and activity of the seeds. Shrink films also need vents to ensure that they will not break when shrinking, but is the punching method better? Seed packaging laser perforated film air holes Shrink film vent holes The air holes processed by the laser marking machine have uniform and adjustable apertures and can achieve easy-to-tear marks in any direction and shape. In addition, the laser film punching machine also has the characteristics of fast engraving speed, simple equipment operation, stable performance, and long service life.
