The application of laser easy-tear lines in packaging bags:

Packaging bags often provide higher sealing, safety, light-shielding, and damage resistance for goods. Among them, products using composite materials typically have higher requirements for hygiene, temperature, humidity, and light. However, the packaging of goods not only needs to be sturdy but also considers the ease of tearing when in use. Therefore, a user-friendly packaging opening is essential. A laser punching machine for packaging bags can create dotted lines in one or multiple layers of composite materials, without compromising the integrity of the packaging's sealing performance. Laser punching is accurate and efficient, a capability that traditional techniques find challenging to achieve.

Advanced laser technology provides us with solutions to our problems. Laser equipment can select individual film layers in flexible packaging for marking. This can achieve a complete tearing effect of the flexible packaging, maintain the integrity of the film, and keep the outer film intact, thus effectively preventing the goods in the package from deteriorating due to light and moisture. Now, advanced laser marking machine systems can be cut in any combination. For example, many daily necessities and food packaging currently use a design style that is based on the outline of the printed pattern on the package. This scribing method is an advantage of laser scribing systems. Likewise, this process is used for pharmaceutical packaging, which not only facilitates opening, but also stores and prevents contamination.

 

The laser perforation and scoring method utilize the laser beam to uniformly cut designed solid lines, dashed lines, wavy lines, easy-tear lines, etc., into fine lines with a depth of only a few micrometers. Due to the focusing advantages of the laser, the focus point can be as small as the sub-micron level, making it advantageous for micro-processing of materials. Laser cutting, marking, scoring, and perforation depth can be controlled. Even at low pulse energy levels, it is possible to achieve a high energy density for effective material processing. Laser technology is applied to cut, score, perforate, and layer-cut soft packaging materials such as OPP, BOPP, PE, PET (polyester), aluminum foil, and paper.

With the widespread application of lasers, their use in the film packaging industry has been further enhanced, and laser processing has become a new technological standard for the polyethylene, PVC, and polyester film processing industries. Guangzhou Lase Laser specializes in providing solutions for film easy-tear lines and quantified breathable holes for packaging.
