As we all know, smoking is harmful to health. Tar cigarettes produced in the combustion process is harmful to human health, leading to the main substance of human cancer. Tar harm reduction is the trend of the global tobacco industry, China's tobacco industry is no exception. State Tobacco Monopoly Bureau is actively promoting cigarettes' tar project "and" tar harm reduction project. " The traditional approach is complex and time-consuming tar, tar and laser drilling method has gained more and more widely used. Over the years, China's tobacco industry to adopt various means to tar effective control. August 1986, China's implementation of national standards cigarettes, will cigarette tar content is divided into high, medium and low three grades. Cigarette tar content of less than 14mg tar content is low, 15 ~ 21mg of tar content, 22mg of high tar content. In order to limit the high tar content of cigarettes, the state must be designed value of tar labels on cigarette packaging. 2004 State Tobacco Monopoly Bureau issued a notice, from July 1, 2004, the tar content of cigarettes in boxes marked 15mg / support above shall not enter the sales market, and gradually the tar content of cigarettes down to about 12mg. This provision also applies to imported cigarettes. Currently the average tar content of cigarettes by China 20 years ago, down to each 30mg each 15mg, and strive to make this an annual average value decremented 0.5mg. Thus, in recent years, China's tobacco manufacturers for the production of cigarette tar on a large scale collective work, the various research units and production companies are taking a variety of means (such as chemical tar, tar and other physical methods) to reduce tar cigarettes content. Studies have shown that air dilution can be reduced by people during smoking intake of harmful substances such as tar, carbon monoxide, so high air permeability of cigarette paper and pre-perforated tipping paper (tipping paper) came into being. Especially perforated tipping paper technology has made rapid development in recent years because of various methods, using laser butt perforated tipping paper quantitatively the most simple and effective method. China's tobacco industry, paper loading dock applications are not only limited to packaging, but also pay attention to its decoration, printing paper loading dock aesthetics also put forward higher requirements. The tipping paper variety, from the development of the original single color to multicolor variety of products, and multicolor Product ratio increased every year. Meanwhile, with the cigarette environmental health is growing, tipping paper itself and food hygiene requirements are also increasingly being valued by the various cigarette manufacturers, and has become an important direction for future development. Therefore, as long as the cigarette still in production, butt perforated tipping paper demand will not disappear, it would be the existence of such a laser drilling machine market demand.
