More than 8 million tons of plastic is dumped into the ocean each year. And the world uses more than 1 million plastic bags per minute, the average "working lifespan" of plastic bag is only 15 minutes, but their degradation requires 1000 years. Plastic has become the number one enemy of humans and has also led to the tragedy of many animal deaths because it can not be national degradation.
However, in the industrial field, compared with other materials, plastics have the advantages of light weight, excellent chemical stability, excellent electrical insulation properties, wide distribution of mechanical strength, and high specific strength, etc., becoming the most commonly used packaging materials and being widely used in daily life.
In addition to the environmental pollution caused by the degradation of plastic materials, the marking of plastic packaging also brings about pollution problems that cannot be ignored. Originally, trademarks, bar codes, and serial numbers on plastic products were usually processed by printing, labeling, hot stamping, shrinking, and packaging, or they were mechanically processed directly on plastic surfaces. This method was not only inefficient, but also with high consumables. And serious pollution occurs during processing.
In 2017, the total output of China's plastic products was 75.155 million tons, an increase of 3.4% over the same period of last year. With the expansion of the application range of plastic materials, the marking methods of its materials have also been updated, from the traditional ink coding to the advanced laser marking. .
The laser marking machine gathers huge energy on the plastic products through the laser beam, thus marking some plastic logos, graphics, manufacturer information, product parameters, and instructions for use. It overcomes the high cost of traditional ink printing. The major problems of pollution, high consumables, high failures, high maintenance, and ease of elimination have become indispensable processing tools for the plastics market.
MRJ UV laser marking machine, using short-wavelength high-quality UV laser, with small focusing spot, light thermal effect, can get a beautiful marking effect. This series of products has unparalleled advantages for the fine marking of plastic products. This equipment is mainly used to print letters, numbers, production batch number, production date, expiration date, LOGO, real-time clock information, anti-counterfeiting and anti-counterfeit digital, etc., to meet the requirements of GMP in the pharmaceutical industry and HACCP in the food industry.
Plastics with its light weight, durability, aesthetics, and low cost, replaced a large number of traditional packaging materials and contributed to a revolution in the packaging industry. However, the impact of plastic products on the environment cannot be ignored. Lasers have their own unique advantages. To protect the environment, we also remind ourselves to choose more environmentally friendly methods to process plastics and minimize the use of plastic products.
