In recent years, domestic laser technology has developed very rapidly, and it has become more and more widely used in different industries. The unique processing method has provided new processing solutions for many enterprises. In the current food packaging, in order to control and extend the shelf life of fresh food, it is necessary to make some small holes on the surface of the packaging bag that are difficult to see with the naked eye during the packaging process. The traditional punching method is difficult to grasp because of the accuracy, so it is difficult to achieve the ideal processing needs in the process of processing. In order to effectively solve this problem, many companies now use lasers to punch holes in the process of processing. Not only can the size, shape and position of the holes be controlled on the micrometer scale, but also the specific functions required can be easily operated.
For example,nowadays, air-conditioned packaging,which is mainly used to extend the expiration date of fresh foods and frozen foods. With the continuous improvement of people's living standards, the quality requirements of products are getting higher and higher, like the current organic fruits and vegetables. The freshness of foods such as nuts, dried fruits and grains depends largely on whether the air in the bags is circulated and whether the humidity in the bags is kept within a certain range, so this requires us to carry out packaging processing,fully flexible to increase the fine pores of the surface.
At the same time, there is still a need for multi-chamber tray packaging on the current packaging market, which is mainly used to package a variety of fast food. In order to effectively improve the optimal storage life of these foods, it is necessary to make different holes in each room. Traditional processing methods have been difficult to meet the current packaging needs due to hygienic and effect factors, and today's laser technology is increasingly becoming an indispensable processing method in packaging production. Not only can the size of the drill be precisely controlled and edited, but it also reduces unnecessary waste and reduces costs. It is believed that in the future, the application of laser technology in the food industry will be wider, injecting new power into the current packaging production for people and life offers higher quality products.
