Vacuum spray aluminum paper (also known as spray aluminum paper, aluminum paper, vapor deposition paper) is a new type of green packaging material widely used in the packaging industry since the 80s. It has a strong metal texture, low material cost, good flexibility, stable and reliable printing performance, degradable, recyclable, and thus more and more people's favorite. In 1992, vacuum sprayed aluminum waterproof label paper entered China's beer bottle packaging market and was quickly applied. In 1998, the national demand was about 6,000 tons, of which domestic paper accounted for about 60%. In 1993, vacuum ejected aluminum (gray) cardboard was applied in the fields of domestic liquor, tea, cosmetics, food, food and gift packaging. In 1997, vacuum aluminum sprayed cardboard entered the domestic cigarette packaging market, and gradually replaced high-priced and non-environmentally friendly packaging materials such as traditional aluminum foil cards and coated cards. It is expected that by the year 2000, vacuum aluminum spray liners will also enter China's cigarette packaging market.
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 on the vacuum aluminum sprayer to spray aluminum, but this method is limited to aluminum spray paper. In the transfer method, the PET film or film light PET film is first sprayed on a vacuum aluminum sprayer, then glued and compounded with paper or paperboard, and finally the PET film is peeled off (the PET film can be used repeatedly several times), The layer of aluminum molecules is transferred to the surface of the paper or board by gluing. The use of the transfer method can produce paper or board of 40 450 g/m2 or more.
Compared with the direct method, the transfer method has the following advantages: 1 It can produce aluminum spray paper or cardboard with any thickness. 2 Make full use of the flatness of the PET film to make the paper metallic luster brighter. 3 Laser anti-counterfeit vacuum aluminized paper or cardboard that can produce any pattern and text.
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. Therefore, the production of anti-counterfeit packaging materials using the transfer aluminum spray method has unique advantages. The five comprehensive indicators put forward by the international anti-counterfeit packaging materials are: 1 Timeliness. It means that the security material is difficult to be simulated by others in a certain period of time. 2 appearance. Excellent anti-counterfeit packaging materials should be organically combined with the aesthetics of packaging design and printing. 3Identity. Anti-counterfeiting of packaged products should be easily identifiable so that consumers can see them before purchase. 4 versatility. Advanced anti-counterfeit packaging materials must have universal application in the printing and packaging industry. 5 economy. Advanced anti-counterfeit packaging materials have high technological content and prices can be accepted by the market.
As a brand-new packaging material, laser anti-counterfeit vacuum aluminum spray paper can meet the above requirements and has better anti-counterfeiting properties. Shenzhen Jinwei Special Beer has adopted laser anti-counterfeit aluminum spray bottle stickers since 1995, and no counterfeit products have been found so far.
Shanghai Zijiang Aluminum Spray Packing Material Co., Ltd. is the first large-scale enterprise to introduce advanced vacuum aluminum spray equipment and transfer aluminum spray technology in China. It can produce laser vacuum spray aluminum paper. Zijiang Company has produced vacuum aluminum spray packaging materials since 1986, with a monthly production of 4 million m2 and an annual production value of 170 million yuan. In 2000, the company will continue to invest 15 million US dollars, when the annual output value can be increased to 450 million yuan. In 1998, the company produced vacuum sprayed aluminum waterproof wine label paper accounted for 35% of domestic aluminum spray paper beer bottle label market, and vacuum sprayed aluminum cards accounted for 100% of the domestic cigarette packaging market. With the development of China's packaging and printing industry, vacuum aluminum spray paper and anti-counterfeit laser vacuum aluminum spray paper will be popular in the market. (Dai Yuchao)
