First, aluminized paper packaging market
Aluminum-plated paper is mainly composed of base paper, aluminum layer and coating. It is widely used due to its good gloss, smoothness and flexibility, high fastness to aluminum spray, beautiful and environmental protection, good printing performance and mechanical processing performance. The exquisite packaging of cigarettes, wine, bottle stickers, tea, food, cosmetics, daily chemicals, department stores, gifts, and handicrafts can also be used for construction and decoration materials. The market for aluminum-plated paper in China has a large space for development. According to incomplete statistics, there are nearly 30 companies that have already established or are investing in aluminum-plated paper projects. Some companies have large-scale and advanced equipment.

Second, vacuum aluminum plated paper and laser paper

Vacuum aluminum plated paper jam

Vacuum aluminum coated cardboard is a kind of metallic glossy paperboard. It is a high-grade 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 aluminum foil and paperboard. PET laminated paperboard is a combination of aluminum foil and paperboard. The surface of aluminum foil and plastic cannot achieve degradable, recyclable environmental performance. Because of the method of vacuum aluminum plating, only a thin layer of 0.25 um to 0.3 um thick and bright aluminum is covered on the surface of the cardboard, which is only one-fifth of that of aluminum foil and aluminum foil, so it is not only 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. The direct method is to place the paper directly in a vacuum aluminum plating machine for aluminum plating; the transfer method is to place the PET film in a vacuum aluminum plating machine after aluminizing, and the glue is combined with the paper, and then the PET film is peeled off and the aluminum molecular layer passes through Adhesive transfer to the cardboard surface. 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. It 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.

Vacuum aluminum plated packaging material is a new type of composite environmental protection packaging material, which gradually replaces aluminum foil composite paper as aluminum paper. 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, in most countries in Europe, vacuum aluminum paper is used instead of plastic film and aluminum packaging paper in packaging of gifts, toys, food, tobacco, wine and daily necessities. The reason is that Europeans attach great importance to environmental protection and advocate the protection of nature and the protection of the earth's lifestyle.

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 spray aluminum 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 directly place the paper in a vacuum aluminum sprayer for aluminum spraying. This method is limited to aluminum spraying on thin paper. The transfer method is to place the PET film or laser PET film on the glued horse paper or cardboard composite, and then The PET film peels 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-counterfeit packaging materials, the transfer aluminum spray method has unique advantages. The international packaging industry put forward five comprehensive indicators for anti-counterfeit packaging materials: First, the timeliness. Anti-counterfeiting 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 therefore difficult to counterfeit.

The longer the time for this anti-counterfeiting scientific and technological achievement to stay ahead, the better the anti-counterfeiting effect; the second is aesthetics. An excellent form of anti-counterfeiting should be accepted by the market; the third is identification. The anti-counterfeit effect must be clear to the consumer before purchase; the fourth is generality. Advanced anti-counterfeit packaging materials must have universal application in the printing and packaging industry. Manufacturers do not need to add additional equipment, without special training can be applied to the production of conventional packaging; Fifth, economical. Advanced anti-counterfeit packaging materials must have high scientific and technological content, and the price can be accepted by the market, so that the goods can increase the credibility and profitability of the manufacturer on the basis of eliminating counterfeiting.

These five highly demanding comprehensive indicators have been a problem that has plagued the packaging industry for many years. The excellent characteristics of laser anti-counterfeit vacuum ejector paper (card) are extremely close to the above five comprehensive indicators and are an ideal anti-counterfeit packaging. Materials, its application prospects are extremely broad.

Third, aluminum coated paper conforms to the trend of environmental protection

From the packaging of cigarette packs, from the soft packs, ordinary white card hard packs to glass cards, and the popular aluminum foil gold and silver cardboard in recent years, to the introduction of high-grade matte process using PET composite cardboard, China Tobacco Packaging has been walking The forefront of the packaging industry. Although aluminum foil gold and silver paperboard and PET composite paperboard have formed high-grade packaging materials with good decorative performance and anti-counterfeiting performance, they are non-environmental materials. In order to meet the requirements of environmental protection and reduce the need for cigarette packaging costs, the use of aluminum-plated cardboard instead of name foil cardboard and aluminized gold and silver cardboard is an inevitable trend.

The greatest advantage of the composite aluminum foil liner is good formability and excellent sealing. Now the aluminum spray paper not only meets the requirements of the cigarette pack in terms of performance, but also the thickness of the aluminum layer of spray aluminum paper is only 1/200 of the composite aluminum foil. The weight is only 1/125. In the transfer of sprayed aluminum paper, due to solving the problems of brightness, folding resistance and printing adaptability, compared with aluminum foil composite card and PET composite paperboard (commonly known as “bright card”), it has better cigarette pack forming performance and is not Burst, invariable features. Aluminum foil gold and silver cardboard can neither be recycled as aluminum products, nor can it be recycled as paper. PET composite paperboard is a composite product of aluminized film and paper. Because plastic film cannot be degraded, it is not conducive to environmental protection. Western governments use tax policies to promote the use of environmentally friendly materials, making aluminum spray liners widely used in recent years. Because aluminum-sprayed lining paper is classified as a single material, it is taxed at 0.4 DM/kg, while aluminum foil compound lining paper is used as a composite product, with a taxation of 2.10 DM/kg. This legislation has had an explosive effect on the cigarette industry. The original packaging materials for aluminum foil composite papers began to switch to aluminum-plated paper. Aluminum spray paper and transfer aluminum spray paper have also begun to receive widespread attention and application in China, especially the application of cigarette packaging materials. After solving a series of problems in printing and forming technology, aluminum spray paper, especially transfer aluminum spray paper, has been applied to cigarette packs on a large scale.

The thickness of the aluminum foil composite liner is 7 microns, while the aluminum thickness of the aluminum liner is only 0.02 microns, a difference of more than 300 times, but their appearance is almost the same as the barrier properties of steam, water, and light, and the spray Aluminum liners are easier to recycle, burn, and easily oxidatively degrade after being discarded. After the cigarette packs are discarded, their aluminum is oxidized in a short time and will not cause environmental pollution. After the wastes are collected, they can be sent back to the paper mill for recycling. The price of aluminum-sprayed cardboard is 10% lower than that of aluminum foil; the speed of cigarette packaging machines on cigarette labels printed with aluminum spray paper is significantly higher than that of cigarette labels made with aluminum foil composite paperboard (approximately 200 bags/minute higher). Due to the above reasons, the widespread use of aluminum spray paperboard will also form an unstoppable trend.
