Application of laser tear lines in packaging of removable disinfection tissues

Application of Laser Tear Line in Packaging Bags

Packaging bags often have higher sealing, safety, light-shielding and anti-destruction properties for the packaging of goods. Among them, goods using composite materials usually have higher requirements for hygiene, temperature, humidity and light. However, the packaging of goods must not only be sturdy, but also consider the ease of opening and tearing during use, so a humanized packaging opening is very necessary. The packaging bag laser punching machine can punch dotted holes in one or more layers of composite packaging materials without destroying the complete sealing performance of the packaging. Laser punching is accurate and efficient, which is difficult to achieve with traditional punching technology.

Advantages of laser tear line technology for removable packaging bags for disinfection wipes/wet tissues

Advanced laser technology provides us with a solution to the problem. The laser equipment can select a separate film layer in the flexible packaging for marking. This can achieve a complete tearing effect for the flexible packaging, maintain the integrity of the film, and keep the outer film intact, thereby effectively preventing the light and moisture in the package from causing deterioration of the goods. Nowadays, advanced laser marking machine systems can be combined arbitrarily for cutting. For example, many daily necessities and food packaging are currently designed to be marked according to the outline of the printed pattern on the packaging. This marking method is the advantage of the laser marking system. Similarly, this process is used for pharmaceutical packaging, which is convenient for opening, storage and pollution prevention.

Special-shaped opening tearing laser marking function

The laser punching and marking method uses the beam generated by the laser to evenly cut the designed solid line, dotted line, wavy line, tear line, etc. into a thin line with a depth of only a few microns. Due to the advantage of laser in focusing, the focusing point can be as small as the sub-micron order of magnitude, 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, a high energy density can be obtained to effectively process materials. Laser technology is used to cut, score, punch, and layer-cut flexible packaging materials such as OPP, BOPP, PE, PET (polyester), aluminum foil, and paper.

Due to the wide application of lasers, the application of lasers in the film packaging industry has been further improved, and laser processing has become a new technical standard for the polyethylene, PVC, and polyester film processing industries. Guangzhou Laisai Laser specializes in providing solutions such as film tear lines and quantitative air holes for packaging.
