【Chinese Packaging Network News】Laser scribing is a process that uses lasers to achieve easy-pulling results on multi-layer composite packaging materials. It can be used to scribute a thin film layer in a package without damaging the entire film.
The competition in the supermarket can be seen everywhere. Every commodity on the shelves is trying to sell first. In order to arouse people's desire to purchase, various foods are all up and down the design. In the consumer goods industry, packaging has always been an important aspect of special attention. The exquisite degree of packaging is directly related to the sales of goods. However, under the gorgeous appearance, some details are rarely known.
I believe that everyone will encounter such a dilemma, want to tear open the food packaging, but how can not open, hand tearing, mouth bite, after tossing for a long time, the food in the bag has become detritus. This is because the traditional scribing method makes the scribing too shallow, and conventional tools can easily draw the line too deep, resulting in damage to the composite layer of the product package. A small line affects the consumer experience and product quality.
Laser scribing technology solves this problem perfectly. Laser scribing is a process that uses lasers to achieve ripping results on multi-layer composite packaging materials. It can be used to scribute a film layer in a package without damaging the entire film. It is noteworthy that the laser marking technology is a non-contact and non-abrasive process for food packaging, and also ensures that the products in the packaging are not damaged due to the packaging process, ensuring the stability and reliability of the product.
Carbon dioxide lasers are ideal for food packaging applications, where transport and adsorption properties can provide accurate scribe depth. Food packaging mostly uses composite membrane materials such as PET, PP or PE, which have different absorption and emission carbon dioxide laser wavelength characteristics, so when a layer of film absorbs laser energy and disappears, the other material film layer is 100% Stay intact without any impact. On the other hand, aluminum foil or other metal-plated films act as a barrier to the laser's access to other material layers, so the properties of these materials can enable laser technology to accurately position and scribing the packaging material. .
The advantages of laser marking technology for food packaging:
1, only the selected thin film layer, other film layer is not affected
It is free to choose the shape of the scribe
3, less loss in the production process, reliability
