Develop green cosmetic tube printing

What are the main points that need to be paid attention to in the development of green cosmetic tube printing, and how much do you know? Let’s take a look at the cosmetic tube manufacturer below

1. Printing material-paper

From the perspective of affecting the environment, cosmetic tube materials are an important factor that directly affects the environment, so the choice of cosmetic tube materials should meet the requirements of green and environmental protection. The evolution process of consumer demand for paper (ordinary cosmetic tube-high-end cosmetic tube) can intuitively allude to the replacement trend of cosmetic tube materials (white cardboard-gold and silver cardboard). In the choice of raw materials for cosmetic tube manufacturers, the vacuum aluminized paper and composite gold and silver cardboard in gold and silver cardboard have good smoothness, high smoothness, bright color, bright appearance, strong visual impact, moisture resistance, and The obvious oxidation effect and other characteristics greatly satisfy the visual effect and use effect, and improve the grade of cosmetic tube printing cosmetic tube products. However, from the perspective of environmental protection, a large number of non-degradable materials such as aluminum foil composite or PET coated cardboard with rich metallic luster and high gloss are used, which is easy to cause environmental pollution and inevitably bring environmental crisis. In combination with the final realization effect of the product cosmetic tube, the current environmental protection advantages of cosmetic tube printing are mainly: traditional four-color ordinary paper cosmetic tube printing, white cardboard printing metal ink and large-area hot stamping technology, and vacuum aluminum plating materials Replace the composite aluminum foil paper cosmetic tube printing. The use of recycled paper in the printing of cosmetic tubes is also a future trend. However, in actual applications, recycled paper has low paper strength, insufficient ink drying, easy scratches, insufficient whiteness of the paper, and poor abrasion resistance to a certain extent. It limits its scope of application. Although the printability of recycled paper for cosmetic tubes is not comparable to that of traditional pulp paper, its potential is huge from the perspective of environmental protection. Changing the physical properties of paper can also achieve good results, such as using dyeing, embossing and other methods to improve the uniqueness and novelty of the product. With the deepening of people’s awareness of environmental protection, cosmetic tube printing companies should pay more attention to improving the environmental performance of cosmetic tubes and cosmetic tube printing, choosing energy-saving, low-consumption, non-toxic, non-polluting, reusable, easy to dissolve, and multifunctional , Pollution-free cosmetic tube printing material for cosmetic tube.

2. Ink

Ink is indispensable in the cosmetic tube printing industry, and the amount of use is large, but the harm to human health and the environment is the most serious. The cosmetic tube printing ink is composed of pigments, bonding agents, solvents, and auxiliary agents. At the application level of the ink, the volatilization of VOC (volatile organic compound) in the ink will cause a serious greenhouse effect, form photochemical smog, and damage the human nervous system. In addition, the heavy metal elements such as pliers, chromium, mercury, etc. in the ink pigments will also cause certain harm if the ink containing heavy metals is used for the printing of food and cosmetic tubes or cosmetic tubes that are in close contact with the human body. In order to reduce the damage of ink to the environment, the trend of using environmentally friendly ink is becoming more and more obvious. The (ROHS Directive) adopted by the European Commission stipulates that since July 1, 2006, new electronic equipment products (including product cosmetic tube materials) sold on the EU market are required to not contain lead (Pb), cadmium (Cd), and mercury (Hg), hexavalent chromium (Cr+6), polybrominated biphenyls (PBB) and polybrominated diphenyl ethers (PBDE) and other six hazardous substances, clearly stipulate lead (Pb), mercury (Hg), hexavalent chromium (Cr+6) and polybrominated biphenyls ( The maximum allowable content of PBB) and polybrominated diphenyl ether (PBDE) is 0.1%, and the maximum allowable content of cadmium (Cd) is 0.01%.

3. cosmetic tube printing method

In the cosmetic tube printing industry, the actual effect of cosmetic tube printing is closely related to the selected cosmetic tube printing method. According to the current status of the industry, the choice of printing methods for cosmetic tubes will have a direct or indirect impact on the environment. In the printing method based on flat, convex, concave, and other four major cosmetic tubes, the bottleneck of the environmental protection application of offset (offset) printing is ink and fountain solution. In addition to the use of environmentally friendly offset printing inks, the current trend is to try Waterless offset printing, traditional offset printing fountain solution contains volatile isopropanol and other toxic organic substances, which will be inhaled by the human body for a long time, which will affect the function of the kidneys and lungs. On the one hand, waterless offset printing uses non-solvent inks on the other hand. The ink-repellent silicone resin coated printing plate can absorb the ink by removing the coating on the image and text part, and realize the transfer of the image and text. Therefore, it does not need a fountain solution to achieve ink and water balance. Ink is the bottleneck of the environmental protection application of gravure and screen (perforated) cosmetic tube printing; relatively flat, concave, and other three cosmetic tube printing methods. In other cosmetic tube printing, flexographic cosmetic tube printing is used in environmental protection applications. The advantages are obvious: it uses water-based ink and does not contain toxic organics, which is in line with the green development trend of modern cosmetic tube printing. The biggest feature of water-based ink is that it significantly reduces VOC emissions, thereby reducing air pollution and improving the working environment of the cosmetic tube printing workshop.

4. Printing process of cosmetic tube manufacturer

In the entire process of printing, the choice of cosmetic tube printing method has a great impact on the environment, but in actual work, in addition to the environmental factors caused by the raw materials and auxiliary materials themselves, various improvements in the production process can also be used. Received certain results. In the cosmetic tube printing process, untreated dampening waste, car wash waste, varnish waste, cleaning plate waste, water bucket waste, waste ink tanks and other liquids and solids are randomly discharged (treated). Will cause harm to the natural environment. In response to this situation, companies must plan and step-by-step environmental reforms in accordance with conventional methods, such as building waste liquid filtration systems (including sedimentation, filtration, centrifugal treatment, etc.), and establishing waste product classification and centralized recycling methods to reduce environmental impact. Impact. This mainly depends on the strength of the company's environmental awareness and the size of the company's social responsibility.

5. Post-press processing for cosmetic tube manufacturers

In the post-printing process of cosmetic tubes, the processes of laminating, glue application, and product protection are equally important. For example, the film coated on the surface of the cosmetic tube printed matter is as difficult to degrade as other plastic products. On the one hand, it is easy to cause white pollution, and on the other hand, the coated paper cannot be recycled again. In response to this situation, the promotion and use of a brand-new pad printing (transfer film) technology has received a good environmental evaluation. The key to pad printing (transfer film) technology is the production of pad printing film. It uses the principle of light vision to form a similar pattern on the surface of the cosmetic tube printed matter through pressure and a connecting agent during the contact between the pad printing film and the cosmetic tube printed matter. The effect of holographic film. However, the transfer film can be reused many times, and the product effect after pad printing can be comparable to the effect of the film. At the same time, the pad printing product is waterproof and degradable, which is beneficial to environmental protection. In terms of glazing, water-based varnish is used to ensure that the printed products are non-toxic and tasteless.

6. cosmetic tube manufacturer's internal system

Introduce an international mature system to regulate corporate behavior and enhance the company’s comprehensive management and control capabilities. Such as the ISO14000S environmental management system, of which ISO14001 is the basic standard of the environmental management series, and is the basis for enterprises to establish and implement the environmental management system and pass the certification. Its basic idea is to prevent and reduce environmental impacts and continuously improve environmental management. The cosmetic tube printing industry should learn from and use the ISO14001 environmental management system to continuously improve the environment and prevent pollution.

In short, with the increasing degree of global environmental pollution and ecological damage, there are growing calls for concern for life, environment and development. Establishing environmental awareness and vigorously developing the green cosmetic tube industry has become an important way to break the green barriers of international trade and promote the development of environmental protection, and it is also an inevitable choice for sustainable development. For cosmetic tube manufacturers, there is an environmental protection atmosphere at present, but the important thing is how cosmetic tube printing companies can implement specific requirements. Environmental protection is a challenge and opportunity brought by new technologies and markets. It is an important part that is conducive to the development of enterprises in the long and short term. Manufacturers of cosmetic tubes have also accelerated the pace of environmental protection, increased their environmental protection efforts, and introduced many environmental protection laws and regulations. To ensure its steady development, cosmetic tube manufacturers must adapt to new policies and the pace of change, adjust environmental protection measures, and cosmetic tube manufacturers solve the pollution problems involved in production and customer products.
