With the rapid development of modern industry and the continuous enhancement of public opinions on environmental protection, the application of paper packaging in commodities has become more and more extensive and the demand is increasing. Luoyang Lai Saier Technology Co., Ltd. meets market demand, the introduction of domestic advanced equipment and instruments, production of vacuum aluminum paper.
Good market prospects
Aluminized paper is mainly composed of base paper, aluminum layer and coating. It is widely used due to its good lightness and smoothness, good flexibility, high aluminum spray fastness, beautiful appearance and environmental protection, and good printing performance and mechanical processing performance. For exquisite packaging of cigarettes, wine, bottle stickers, tea, food, cosmetics, daily chemicals, department stores, gifts, handicrafts and other products, can also be used for construction and decoration materials.
The market for aluminum-plated paper in our country has a large space for development. According to incomplete statistics, there are nearly 30 companies that have already built or will invest in aluminum-plated paper projects. Some companies have large-scale and advanced equipment.
1, tobacco packaging
The aluminum coated paper applied to the inner liner of hard-packed cigarettes has a certain degree of fixation. The number of folding times of the hard-shell packaging made of aluminum-plated paperboard is double that of the aluminum-foil composite paperboard. The raw and auxiliary materials used in the production of aluminized paper are not available. Odor, non-toxic, in line with US FDA standards.
The hard coated cigarettes and the aluminized papers used in alcoholic beverages have good glossiness and smoothness, good printing performance, and are suitable for embossing, die-cutting and embossing and other mechanical processing. At present, aluminum spray paperboard has an extension and upgrade follow-up product - laser molded anti-counterfeiting aluminum spray paperboard. It uses high-tech to carry anti-counterfeit brands, trademarks, patterns, and signals onto the aluminum spray surface to achieve a very good anti-counterfeit effect; and Aluminum paperboard can not only use gravure printing, offset printing, screen printing and other printing methods, but also use UV ink, ice flower technology, no ink printing embossing, making the printing art has been a good show.
In the early 1980s, as people's awareness of environmental protection increased, European and American countries began to try to use aluminum spray products instead of composite aluminum foil in tobacco packaging for cigarette lining packaging.
At present, the large application market for aluminized paper is North America and Europe, which account for 80% of the world market. The annual consumption of aluminum coated paper in North America is 120,000 tons, of which labels account for 60% and the tobacco industry accounts for 18%. The annual consumption of aluminum coated paper in Europe is 90,000 tons, of which flexible packaging accounts for 51%, labels 15%, and the tobacco industry 14%.
Entering the 1990s, with the rapid development of China's industry, environmental protection issues have also been mentioned on the agenda of the country. It is against this background that aluminum spray products are the new environmentally friendly products for aluminum spray products. In the use of cigarette linings, China's annual tobacco production is about 34 million large boxes. Calculating the consumption of 30 tons per 10,000 large boxes, the total market demand for cigarette lining paper is about 100,000 tons. Currently, composite aluminum foil is mainly used. In recent years, tobacco companies have made use of aluminum spray paper on cigarette packs as an important topic. Shanghai Tobacco Group has determined to use aluminum-sprayed lining paper for “Giant Pandas†in 2004. Honghe Tobacco Factory started last year. It has been put into use on two cigarette packs. In the next three to five years, the amount of aluminum spray paper used on the liner will be estimated at 6-7 million tons. For the transfer of aluminum spray paper, according to the current annual production of about 34 million large boxes of cigarettes, a total of approximately 400,000 tons of internal and external packaging paperboards are required. In 2002, the amount of transferable aluminum spraying paper in the country was allowed to be 25,000 tons, while the amount of composite aluminum foil paperboard and PET composite paperboard was about 15-18 million tons, and the rest was white cardboard. About 20 large tobacco companies across the country have begun to use aluminum spray products as a preferred packaging material in their products.
2, cosmetic packaging
The main consumer groups of cosmetics are women. Whether cosmetic packaging is exquisitely affects the position of cosmetics in women's minds and their preference for specific brands. Vacuum aluminum-plated paper printing transparent colorful ink, can reveal the noble and rich metallic luster, while giving a psychological hint: After using this kind of cosmetics, they can also shine, and easy to print. Vacuum aluminum coated paper is easy to laser holographic processing, with a good anti-counterfeiting effect. According to the needs of different cosmetics on the packaging printed with a flash of laser LOCO or a specific beautiful pattern, both beautiful and fresh and easy to identify, but also prohibitive counterfeit products.
3, wine packaging
High-strength strong beer label aluminum-plated paper, the main application of a printable and recyclable glass bottles of labels (including body mark, back label, neck label, etc.). This type of aluminized paper has good alkali resistance and lye permeability, good printing performance, suitable for offset printing, gravure printing and flexographic printing, etc. It has good bottle sealing performance and good off-label performance when washing bottles. The sprayed aluminum label paper made from imported base paper has the properties of water resistance, waterproofness, and not curling. It is mainly used for labeling of printable and recyclable glass bottles (including body marks, back labels, neck labels, etc.). In order to give the wine label paper an elegant effect, surface embossing can be used to make the label look distinctive.
4, food packaging
Aluminized paper for food and pharmaceutical packaging can solve the problem that powdery medicines cannot be poured out of powdered powder due to electrostatic attraction. The aluminized paper aluminum layer of candy and chewing gum packaging has good fastness, does not dealuminate when twisted and packaged, and has good printing performance. The bottom paper used in the production of aluminized paper does not contain fluorescent whitening agents, and the chemical materials used are odorless and non-toxic, and conform to the FDA standards.
Two kinds of aluminum coated paper
1, vacuum aluminum plated paper jam
Vacuum aluminum coated cardboard is a kind of metallic glossy cardboard, which is a high-grade and novel packaging material developed in recent years. This kind of paper has bright color, strong metallic sensibility, and bright and elegant prints. It can replace the large-area gilding of printed materials, and it also serves as a icing on the cake for the beautification of products.
Vacuum aluminum-plated cardboard is different from aluminum-based cardboard and PET laminating paper jam: aluminum-based cardboard is a combination of aluminum foil and cardboard. PET laminating paper is a combination of aluminum foil and cardboard. Aluminum foil and plastic on the surface cannot achieve the degradable and recyclable environmental protection properties and cannot be used as green packaging in the world. Vacuum aluminum-plated paper is a novel green packaging material widely used in the packaging industry since the 1980s. Because of the method of vacuum aluminum plating, only a layer of 0.25-0.3 micron thin and bright aluminum layer is covered on the surface of the cardboard, which is only one-fifth of the aluminum foil aluminum foil layer, so that it is With noble and beautiful metal texture, it also has degradable and recyclable environmental protection properties. It is a kind of green packaging material.
Vacuum aluminum-plated paper according to its production process is divided into direct evaporation method (paper surface aluminum plating) and transfer evaporation method (film surface aluminum plating) two, direct method is to place the paper directly in the vacuum aluminum plating machine for aluminum plating Method, the transfer method is to place the PET film in a vacuum aluminum plating machine after the aluminum plating, glue and paper composite, and then strip the PET film, the aluminum molecular layer is transferred to the cardboard surface by adhesive action. Aluminizing paper produced by direct evaporation method, aluminized layer and the loose structure of each coating along the paper surface fiber, the surface is fine with fine pores, poor smoothness, and its flatness is still not suitable for packaging printing, transfer evaporation The aluminized paper produced by the method, the aluminum coating layer is transferred with PET film and paper bonding, the aluminum film is good flatness, strong metal luster, high smoothness, more suitable for packaging printing.
Compared with the direct evaporation method, the transfer evaporation method also has the following characteristics: It can make full use of the flatness of the PET film to make the metal surface of the paper more glossy; it can produce a variety of patterns of laser anti-counterfeit vacuum aluminum coated cardboard. Luoyang Lai Saier Technology Co., Ltd. is a new packaging enterprise specializing in producing all kinds of vacuum aluminized packaging materials and other products. From August 2003 to now, Lysell has invested 20.60 million yuan in technology, the factory covers an area of ​​1200 square meters, construction area of ​​5195.61 square meters, the introduction of the current domestic more advanced equipment, and the introduction of talents, hired aluminum plating in coastal areas Experts, set up a new product development team. After more than a thousand trials and trials, it finally produced a environmentally friendly vacuum-aluminized cigarette inner liner, aluminum-plated cardboard, and beer label with stable quality and performance indicators that meet or exceed the standards of similar domestic products, while prices are significantly lower than those of imported products. , food packaging paper, gift wrapping paper five series of more than 100 kinds of new products. The grammage of environmentally friendly vacuum aluminum coated packaging materials developed by Lyocell is 25% lower than that of other domestic aluminum foils. After comparing the cost of the two products, the use of double-aluminum lining paper consumes 33.1 tons per 10,000 large boxes, while the use of vacuum aluminum-coated lining paper only consumes 229,000 tons per 10,000 large boxes. China annually consumes 160,000 to 180,000 tons of aluminum lining paper. If vacuum-coated aluminum paper is used, it will save about 50,000 tons of aluminum-backed lining paper each year, which can reduce the production cost by 1 billion yuan. For this reason, since the successful development of this product, Lysell has been welcomed by the domestic cigarette manufacturers, especially by the New Tobacco Group. Lysell quickly occupied the market and has been actively expanding.
Vacuum aluminum plated packaging material is a new type of composite environmental protection packaging material. It gradually replaced aluminum foil composite paper as aluminum paper substrate. It is a green packaging material that is conducive to environmental protection because it has a green and environmental-friendly property that can be recycled and can be degraded in the soil, and it can save metal resources. At present, most countries in Europe use vacuum aluminum-plated paper instead of plastic film and aluminum-backed packaging paper for packaging such as gifts, toys, food, tobacco and alcohol, and daily chemical products.
2, laser paper
Laser sprayed aluminum paper (referred to as laser paper) is a laser holographic pattern or text signal is loaded onto the surface of the aluminum spray paper by molding. Vacuum aluminum-plated paper according to the production process can be divided into direct (aluminum paper surface) and transfer method (film surface spray aluminum) two. The direct method is a method in which the paper is directly placed on a vacuum aluminizing machine for spraying aluminum. This method is limited to aluminum spray paper. In the transfer method, a PET film or a laser PET film is placed on a glued horse paper or paperboard composite, and the PET film is peeled off (the PET film can be used repeatedly), and the aluminum molecular layer is transferred to paper or paperboard by adhesive action. The transfer method can produce random anti-counterfeit vacuum aluminized paper or cardboard with random patterns, arbitrary letters. Due to the complex production technology of the transfer aluminum spray method, high technological content, and large investment in equipment, it is difficult for ordinary small and medium-sized enterprises to imitate.
