Now our planet of ecological environment has been very poor, mainly is the industry after the revolution, only pay attention to improve production, and ignore the environment protection. Because a large number of greenhouse gas emissions, forests caused by melting polar ice, cut down, sea levels to rise, the global climate abnormal. In China over the past few years, many of the city by problem of desertification frequently suffered attacks. The dust storm This is simply the pursuit of economic over-grazing, forest and vegetation destruction creates. Environmental pollution is more and more serious, cause great harm to human health, and some disease incidence is greatly increased. As a traditional printing, the main source of environmental pollution: education version liquid, film and the fixer, plastic coated, oily glazing material, etc. As the backlash against the environmental protection, environmental protection as a maintenance of human living environment, and gradually become the eternal topic of the printing industry especially packaging industry obligatory responsibility. To solve the packaging industry problems of environmental pollution, and must have a comprehensive solution. As consumer strengthening of environmental protection consciousness, consumers in the selection of a particular products in addition to focus on the product itself, more attention to product outer packing. This trend with main output result for the goods of the outer packing printing enterprise, the green production, environmental protection is like a huge banner, has become a part of the core competitive ability. In each step of printing, all kinds of raw materials, auxiliary materials is very important. In printing enterprise, the production of printing packaging materials, to what can be and direct contact with food, what is biodegradable, and in the process of production in what factors affect the environment, these are our each printing workers need to think of the problem.
A printing paper, material,
From the Angle of impact on environment, packing material is directly affect the environment of the important factors, so the choice of packaging material more should comply with the green environmental protection request. Consumer demand for paper of the evolution process of (common packing-high-grade packaging) can be directly alluding to the replacement of packaging material trend (white cardboard-gold and silver cardboard). In the choosing of raw materials, the gold and silver cardboard vaccum metalized paper and composite gold and silver cardboard with its smoothness is good, smooth degree is high, bright color, appearance beautiful, strong visual impact, moistureproof, antioxidant effect is remarkable characteristics such as greatly satisfy the visual effect and use effect and improve the printing and packaging the class of the product. However, from the point of view of environmental protection, the use of the rich metallic luster and glossy degrees of the aluminum foil composite or PET coated paper, is not easy to degrade material, easy cause environmental pollution, inevitably leads to environmental crisis. Combined with the product packaging finally realize the effect, which is printing of the more obvious advantages of environmental protection way basically has: the traditional four color ordinary paper printing, white cardboard seal metal ink and large area hot stamping technology, vacuum coating aluminum material instead of compound aluminum foil paper printing. Packaging and printing the recycled paper also is the trend of the future, but in actual application of recycled paper paper strength low, printing ink dry not fully, easy to blow broken, paper white degree is not enough and wear resistance to a certain extent such reason limit its application range. Although the recycled paper printing eligibility can't match with the traditional pulp paper, but from the point of view of environmental protection the potential is great. Change the physical properties of paper can also receive very good effect, such as the dyeing, embossing methods to improve the product's uniqueness and novelty. With the deepening of the people environmental protection consciousness, printing enterprise more importance should be attached to improve the packaging and printing environmental protection performance, choose energy saving, low consumption, non-toxic, non-polluting, can be repeated use, easy to dissolve, multi-function, pollution-free of packaging and printing materials.
Second, printing ink
Printing ink industry, and usage, essential but to human health and the environment is the most serious harm. The printing ink pigment, link by agent, solvents, auxiliary agent composition. In the application of the ink, the printing ink VOC level volatile organic compounds (vocs) can cause serious and the greenhouse effect, still can form smoke photochemical damage the nervous system of the body. In addition, printing ink pigment in the grips, chromium, mercury and other heavy metals, if contain heavy metals ink is used for food packaging or close contact with the human body the printing, the same items can cause certain harm. In order to reduce the ink damage to the environment, use the trend of environmental printing ink more obvious. For example: the water-base printing ink, uv ink, soy ink and so on the new environmental printing ink.
