Application Value of Laser Marking Technology in Food Packaging Industry

Food safety has always been one of the key objects of national concern. In this era of rapid development in which everyone is heading for a well-off society. Consumption can not be contained, so in the field of consumer goods industry, packaging has always been a special concern, food safety has been listed as the top priority. Among them, the safety of food packaging bags is particularly important.
Food packaging bags are an important part of commodities. In addition to the functions of keeping fresh and preserving food, they can also obtain information about food sources, food ingredients, shelf life, storage conditions and so on through the information on the packaging bags. However, due to factors such as commodity transportation and contact, ink marking is prone to the problem of "easy to erase, easy to fall off". At the same time, some criminals will erase the production date of products which are fast overdue, and then spray new production date to continue to sell on the market. This will have a great impact on people's health, but also seriously undermine the principles of the market.
Today, laser technology can provide a good solution. Laser marking laser marking is a marking method that uses high energy density laser to irradiate the workpiece locally, vaporize the surface material or change the color, leaving a permanent marking. It has the characteristics of high marking accuracy, high speed, clear marking and environmental protection and pollution-free. It is depicted on the packaging of the products, so it is difficult to tamper with and counterfeit them; moreover, it is possible to establish a linked database system, so that we can track and inquire the latest trends of the products in time. Therefore, the information marked by laser marking machine, such as the date of production and the source of food, is clear, eye-catching and permanent, which will destroy the packaging if erased. It is environmentally friendly and consumables-free, and it can also effectively restrain illegal elements and provide an umbrella for public food safety issues.
Laser marking, for example, when consumers buy puffed food, the sealing of packaging bags is not good enough, the contents of packaging are easy to overflow, the expiration time will be shortened within the validity period, and some seals are too tight, tearing along the dotted line is very laborious, so it appears that it is difficult to control the strength when opening certain food packaging, the angle of stationmaster consumers. Considering these are all minor headaches, but the laser system of the laser marker can select a single film layer in the soft package for marking. In this way, the perfect and easy tearing effect of flexible packaging can be achieved, and the integrity of the film can be maintained, so that the outer film is intact and intact, so that we can effectively prevent the appearance of problems such as light and dampness of the goods in the packaging.
On the other hand, aluminium foil or other thin films coated with metal become barriers to prevent laser from reaching other material layers. Therefore, the characteristics of these materials can enable laser technology to accurately locate and draw lines on packaging materials. At the same time, tearing the line through the human eye is clearly visible, so it is easy for consumers to tear the packaging. Laser marking and laser drilling technology can effectively prevent the enlargement of small holes and avoid damage to packaging integrity, and can also have good air permeability and moisture retention effect. We have to be shocked by the amazing technology of laser markers.
Laser marking technology is widely used in all walks of life, not just in the electronic industry, in aerospace technology, in mobile phone accessories, light transmission keys, in automobile and motorcycle parts, in military products, in sanitary ware, cosmetics, food packaging, etc. Drug packaging, jewelry, craft gifts and other metal and non-metallic materials are widely used. No doubt, it has been deeply involved in all aspects of your life.
Nowadays, laser marking technology cooperates with on-line operation of production line, which can greatly improve production efficiency and meet the requirements of industrial production. In today's brand era, laser marking technology can better meet the needs of the times.
