Problems of China’s enlarging its analysis of the printing industry – Slurry Pump EGM manufacturer
First, the current problems
While China’s tobacco packaging industry in a number of investment and improvement, but still the following problems:
First, the overall level of technology as compared with foreign countries there are still a large gap;
Second, the hard-flip packets accounted for only 50% of the gentrification process is slow;
Third, excess capacity, equipment idle, too much debt;
Fourth, enlarging its industry, over-reliance on the tobacco industry.
(1) Polyester Film printing adaptability
Polyester Film Direct printing surface, whether it is offset printing, flexographic or gravure printing adaptability will continue to exist and print uniformity and other issues. To achieve good printing results, we must deal with the surface of Polyester Film, the usual approach is first coated with a layer of Polyester Film base oil and then post-order printing.
At present, the base oil used in mainland China, almost 100% of all solvent-based. However, with the environmental requirements, water-based base oil gradually be applied. Water-based acrylic ester-based base oil in the foil above the application of relatively mature, but its Metallized Film There are still some on the application of its own problems.
Latest studies have shown that polyester-base oil in compatibility, adhesion, transparency, etc. are satisfactory results, particularly in stamping performance, excellent, but in China has not yet been widely understood and used in industry .
(B) UV Varnish odor
In China, enlarging its printing almost the highest level of the printing industry. In order to be more competitive, most of the printing factory installed the application of UV ink and UV Varnish UV drying equipment. For most manufacturers, that no matter what kind of printing process, UV system, the residual odor to be a thorny issue.
The system main components are monomers and oligomers, UV light curing mechanism is the promotion of free radical reaction initiator, UV curing process that starts with the surface of the beginning, followed by the surface to inside the final post-curing process to achieve complete curing effect . So what you want to print production lines on the odor, in theory, it is impossible, it is not practical. Therefore, the requirements can only be printed after the post-curing process is no residual odor, the following discussion on the odor problem as follows:
1. Problems
(1) In a non-curing UV varnished surface, the smell from the following aspects
Monomers and oligomers, the nature of their own; photoinitiator smell, which is a major factor in residual odor; UV Varnish in the solvent. Because many manufacturers in order to reduce costs, part of the formula by adding organic solvents such as xylene, etc. In fact, UV varnish coating, the xylene evaporation will produce unpleasant odor.
(2) caused by UV Varnish UV-curing residual odor after the possible reasons for
The intensity of UV light source does not meet the standard, UV Varnish curing the lack of time, which will have a strong residual odor. Photoinitiators choice, photoinitiator residual odor of the film played a key role. Residual Solvents: But most of the UV Varnish system solvent in the post-irradiation, UV light has a clean evaporation. In many cases, unpleasant residual odor is not produced by organic solvents.
2. The solution
Printing and packaging manufacturers to suppliers should be requested when the used in the production of UV Varnish smell the smallest monomer, oligomers, and photoinitiators.
Use of appropriate formulations, printing and packaging plant will be satisfied with not only the surface of curing effect, but also get a better post-curing effect.
Printing and packaging plant to make use of solid content of at least 99.5% of UV Varnish. Note that the performance of UV Varnish test should be conducted 24 hours after curing the coating.
(C) Metallized paper printed a number of problems and solutions
In general, Metallized paper surface flatness, smoothness and gloss than PET Metallized Film composite. Metallized paper makes the print surface is not smooth uneven. In addition, its roughness on the printer and printed in lithography, especially those who made a greater challenge, as offset presses with coating of varnish thinner than flexo gravure press. If the printed image is not flat, folded into a box at the crease line when the office is easy to produce cracks, exposed at the end of paper. Therefore recommended that prior to coating in the printing base oil, so that can not only improve the surface smoothness, but also for the order of printing of a print adaptive better printing surface. In selecting base oil should pay attention to:
1. The flexible base oil
Metallized paper surface by a layer of fine particles of aluminum, in folding, when a deformation, fracture, shrinkage tendency of the smaller cardboard surface, the humidity, the more easy to produce such problems. In addition to ink formulators of the ink performance tuning, must take into account the flexibility of base oil.
2. Friction coefficient
Cardboard surface friction coefficient is to determine the order of the printing process can achieve a key factor in a row to the paper. The cardboard surface friction coefficient of base oil of the nature of the decision, the choice of base oil is critical. In general, the base oil after the more hard-film coefficient of friction, the smaller the more smoother, the more suitable for the machine. Friction coefficient of control must be carefully tested in order to meet the special requirements of each machine.
Second, there is a misunderstanding
(A) over the pursuit of gentrification
With the development of the socialist economy, people’s living standards higher and higher, consumers are increasingly critical eye.
A novel design with high aesthetic value of the cigarette packaging, really can cause consumers to purchase the desire to bring great economic benefits businesses. However, some business over the pursuit of cigarette packaging gentrification, have launched the “Need”, “fine”, “× × King” and other similar packaging, not wait for them to use gold, silver and parcel, into the light-weight leather goods, extreme, and large Most consumers want to buy are affordable commodity. This approach can only turn away from them and really can not afford to buy cigarettes people smoke cigarettes, and aiding the luxury, and corruption in the breeze.
(B) the lack of personality traits, the blind pursuit of “foreign flavor”
Some businesses to seize the part of consumers to worship “foreign goods” mentality, to the product put on a “foreign flavor is” full of packaging, the entire package does not have a character, the implementation of a comprehensive “Westernization”, people almost do not see the Chinese cigarette . As everyone knows, this design style does not adapt to China’s national conditions, China will, after all, knowledge, “foreign language” in the proportion of consumers is not large, so in the minds of consumers is difficult to build brand image, the result can only be counterproductive.
(C) the blind imitation of famous brands
Some merchants spotted some brand-name consumer psychology of worship, they followed suit many approximation, similar to the “name brand” cigarettes, for a time on the market, “Hongtashan”, “Malboro”, “555” and other famous brands of cigarettes twin brother can be seen everywhere, and misleading the consumers, so that consumer rights are infringed. In today’s society, respect for intellectual property rights, maintenance of an increasing demand of intellectual property rights, this practice is bound to the solemn sanctions under the law. According to reports, China has heard more than enlarging its infringement case.
Cigarette packaging design as the design of the tobacco industry is an important component part of the inheritance, to explore traditional Chinese art, innovation, design of both national style, there are characteristics of the times of the cigarette packaging; or into the footsteps, blind imitation, copying other people’s trademarks, it is a sobering thought.
