Laser scribing technology provides new experience for food packaging

The surfaces of different materials need to be marked. Usually we need to use the corresponding laser beam to achieve laser marking. The principle of marking and etching is also very simple, that is, by evaporating the material layer on the surface of the material to expose the deep material and leave traces, or by using light to change the chemical properties of the surface of the material to achieve marking, so as to burn part of the material through heat energy, and finally realize the required engraved pattern and text by setting the path.

Laser tear lines originated in Japan. In the early 20th century, with the aging of Japan and the industrialization of various food items, packaging disassembly became a problem, and even injured the elderly. Therefore, after knowing this defect, manufacturers added tear lines to the packaging to facilitate people at all stages to open the packaging better.

Laser marking of easy-tear lines is also called "laser scoring" technology (Laser Score). It is mainly used to use the characteristics of lasers on multi-layer composite packaging materials to achieve the purpose of "easy-tear edges" of products. Products that use "easy-tear edges" are not uncommon on the market, such as milk and other dairy product packaging bags, soft packaging zipper bags, etc. These daily necessities are particularly challenging to user experience. A bag that is very easy and convenient to tear open neatly will always make users feel satisfied. The Laisai laser scoring machine can help manufacturers achieve this goal. With a more advanced and flexible technology, the micron-sized laser energy is concentrated on the surface layer that needs to be scored for processing, and the laser energy will not cause any damage to other film layers or even the entire film layer. This process can also be called wear-free production and processing, and whether it is a solid line or a dotted line, or different scoring shapes, such as the round easy-tear edge of a carton beverage, it can be easily achieved with a few buttons

Laiser Laser's easy-tear line and quantitative air hole laser marking machines are specially designed for the film packaging industry. One system can be equipped with multiple laser heads and the touch screen can be operated independently. The installation size can be customized according to the customer's existing production line
