Aluminized Paper - Green Pursuit in Packaging Industry (I)

First, aluminized paper packaging market

Aluminized paper is mainly composed of base paper, aluminum layer and coating. It has good gloss and smoothness, good flexibility, high fastness to aluminum spray, beautiful and environmental protection, and good printing performance and mechanical processing performance, so it can be widely used. For exquisite packaging of cigarettes, wine, bottle stickers, tea, food, cosmetics, daily chemicals, department stores, gifts, craft crystals, etc., 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 enterprises that have already built or will invest in aluminum-plated paper projects. Some companies have large-scale and advanced equipment.

1. Aluminizing paper applied to the lining paper of tobacco packaging soft and hard pack cigarettes has certain degree of fixation. The folding endurance times of cigarette hard shell packaging made of aluminized cardboard is double that of aluminum foil composite cardboard, and the raw material for aluminized paper production is used. The auxiliary materials are odorless, non-toxic and meet the 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, designs, and signals onto the aluminum spray surface to achieve a very good anti-counterfeiting 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 products instead of composite aluminum foil for tobacco packaging. At present, the largest 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%. European aluminized paper has an annual consumption of 90,000 tons, of which flexible packaging accounts for 51%, labels 15%, tobacco, lk 14%, gifts 5%, decorative paper 5%, others 10%. Over the past decade, the growth rate of aluminum-plated paper in the North American and European markets has exceeded 6%.

Entering the 1990s, with the rapid development of China's industry, environmental protection issues have also been mentioned by the state on the agenda. It is in this context that aluminum spray products and transfer aluminum spray products have emerged as new environmental protection 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 demand for cigarette lining paper has a potential market of about 10,000 tons. At present, composite aluminum foil is mainly used. In recent years, tobacco companies have used aluminum spray paper as an important topic in their cigarette packs. - Dead Sea Tobacco Group has confirmed that it will use aluminum-sprayed liner paper in the giant panda in 2004. The Red River Tobacco Factory It has been put into use on two cigarette packs since last year. In the next three to five years, the amount of sprayed aluminum paper on the liner will be estimated at 6 to 70,000 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 aluminum spray paper used in the country was about 25,000 tons, while the amount of composite aluminum foil paperboard and PET composite paperboard was about 1,500 to 180,000 tons, and the rest was white cardboard. About 20 large tobacco companies across the country have begun to use aluminum spray products as the preferred packaging material in their products.

2. Cosmetic packaging The main consumer groups of cosmetics are women. Whether or not cosmetic packaging is exquisite 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, mainly used in town printing and recyclable glass bottles labels (including body marks, back labels, neck labels, 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. The pattern of the entire plane gives the label a special charm.

4. Food packaging Aluminized papers for food and pharmaceutical packaging can solve the problem that powdered medicines are not easily poured out of the loaded 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 brighteners, and the chemical materials used are odorless and non-toxic, and conform to the FDA standards.

5. Energy-saving lamp packaging began in the second half of 2003. Philips Yaming Lighting Co., Ltd. energy-saving lamp packaging box using laser spray aluminum paper packaging. The material used in the packaging box of the original Philips energy-saving lamp is a paper composite anti-counterfeiting film. Because of the plastic film, this material is not environmentally friendly. In order to maintain the good image of international companies, it is also a practical reflection of economic, social and environmental coordination. In the development, Philips decided to use environmentally friendly aluminum spray paper on the new packaging of energy-saving lamps. The new packaging box uses 250-300 grams of laser sprayed aluminum paper and is printed by Shanghai Zidan Printing Co., Ltd. on the Roland offset press. Laser spray aluminum paper full name "composite image anti-counterfeit printing and packaging materials", is Zidan Printing will Shanghai Zijiang aluminum spray packaging materials Co., Ltd. production of aluminum spray paper processing, and using a unique dot cover color printing process. Due to the complicated production process and high technical content, the material has a considerable production difficulty, and therefore has a good anti-counterfeiting effect. At the same time, the packaging box made of aluminum spray paper as a raw material, the shelf display effect is very prominent, more glossy and layered than the original packaging. And after the new box has been transported, warehousing and handling, the stiffness, compressive strength and anti-vibration performance are still very good, and the breakage rate is basically controlled to be less than 10,000 ppm required by Philips.

Two, two important 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 laminated cardboard: aluminum-based cardboard is a combination of direct-cut aluminum foil and paperboard. PET laminated paperboard is a combination of aluminum foil and paperboard. Aluminum foil and plastic on the surface of the paper cannot reach the degradable and recyclable environmental protection property 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 from the 1980s. Because of the method of vacuum aluminum plating, only a layer of 0.25-1xm-0.31xm thin, tight and bright aluminum layer is covered on the surface of the cardboard, which is only one-fifth of that of the aluminum foil aluminum foil. It is noble and beautiful metal texture, but also has degradable, recyclable environmental properties, is a 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, the 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. The aluminum-plated paper produced by the direct evaporation method, the aluminized layer and the loose structure of the coating along the paper surface of the coating, the surface is fine with fine pores, and the smoothness is poor, and its flatness is not yet suitable for the printing of the package. The aluminized paper produced by transfer evaporation method is coated with aluminum by PET film transfer. The aluminum film has good flatness, strong metallic luster, and high smoothness, which is more suitable for packaging printing. Compared with the direct evaporation method, the transfer evaporation method also has the following characteristics: It can produce aluminum-coated cardboard with any thickness; it can make full use of the flatness of the PET film to make the metal surface gloss more bright; can produce a variety of patterns of laser anti-counterfeiting Vacuum aluminum coated cardboard.

Zhejiang Aidier Packaging Group Co., Ltd. is a large-scale packaging enterprise specializing in the production of various types of export packaging, color printing carton carton, vacuum aluminized packaging materials and stationery gifts. In the three years from 1999 to 2001, Edel has invested 450 million yuan in three phases, acquired 120 acres of land, built a new 35,000-square-meter garden-like plant, and introduced the most advanced international The equipment of the segment was heavily invested in the introduction of talents, and three experts from the European Aluminizing Industry Association were hired to establish a new product development team. After more than a thousand trials and trials, the prototype has finally been trial-produced with stable performance. The performance index has reached or surpassed that of similar products in the world and can be used as an alternative to the door, while the price is significantly lower: the imported products; the environmental protection is vacuum-coated aluminum cigarette lining paper, Aluminium F paper, beer label stickers, food packaging paper, gift wrapping paper five series of more than 100 kinds of new products. Dill Knife: The weight of environmentally-friendly vacuum aluminum-plated packaging materials is 25% lower than domestic aluminum foil. 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 consumes 22.9 tons per 10,000 large boxes. China annually consumes 1.6 to 180,000 tons of aluminum lining paper. If vacuum-coated aluminum paper is used, it will save about 50,000 tons of double-aluminum lining paper each year, which can reduce the production cost by 1 billion yuan. For this reason, Edel's product has been welcomed by domestic cigarette makers since its successful development. Adel quickly occupied the market and has actively expanded overseas. At the same time, its other four major products have become the new darling of the 21st century packaging forest materials, and the market has broad prospects for development.

Vacuum key aluminum packaging material is a new type of composite environmental protection packaging material section. 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. Nowadays, most countries in Europe use vacuum aluminum-plated paper instead of plastic film and aluminum-covered packaging paper for packaging such as gifts, toys, food, tobacco and alcohol, and daily chemicals.

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 spray paper according to the production process can be divided into direct method (paper spray aluminum) and transfer method (film surface spray aluminum) two. The direct method is to place the paper directly in a vacuum aluminum sprayer 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. In the anti-counterfeiting packaging materials, the transfer aluminum spray method has unique advantages. The international packaging industry puts forward five comprehensive indicators for anti-counterfeit packaging materials: First, the timeliness. Anti-counterfeit packaging must be the latest scientific and technological achievements. In a certain period of time, such scientific and technological achievements are generally difficult for enterprises to grasp and thus difficult to counterfeit. The longer the time for this anti-counterfeiting technology to stay ahead, the better the anti-counterfeiting effect. The second is the United States
