Current situation and development of vacuum spray aluminum transfer paperboard (Part I)

after China's entry into WTO, the impact on China's packaging market will gradually increase. In this process, although foreign packaging companies are not enough to change the current pattern of packaging in China within 3-5 years, these years are an important period for the reshuffle of China's packaging market and the re division of industrial layout. The fierce competition between domestic packaging companies and foreign countries for the retail end market has also opened, and researchers have copolymerized L-LA with GA or dl-la. This puts forward higher requirements for China's packaging industry. The use of new materials, new equipment, new processes and design, and anti-counterfeiting means will become more practical. Environmental protection has become the top priority of these topics

take cigarette packaging as an example. In recent years, China's cigarette packaging has made great progress in expanding the application functions of experimental machines. The packaging of some products has far exceeded the packaging level of some famous international brands. But at the same time, non degradable aluminum foil, gold and silver cards, mirror paper, packaging film, polypropylene fiber, stay wire and other non environmental protection materials are increasingly used. These products are difficult to recycle after being discarded. China is not only a large country of tobacco and alcohol consumption, but also a country with relatively poor resources. The number of tobacco and alcohol packages that cannot be recycled every year is amazing, which not only wastes resources, but also causes environmental pollution. Now developed countries in Europe and the United States have gradually abandoned the paper plastic composite process and replaced it with some new composite paper products (such as vacuum aluminum spray transfer paperboard)

vacuum sprayed aluminum transfer paperboard, commonly known as transfer gold paperboard, this kind of gold paperboard not only has a gloss comparable to that of glass paperboard, but also has matte and bright colors. Therefore, transfer gold paperboard has become an internationally popular environmental protection packaging material with its advantages of high quality and easier recycling. At present, there are two kinds of gold card paper, printing type and composite type, which are widely used in the domestic packaging industry. As a new environmental protection packaging material, vacuum aluminum spray transfer card paper, the introduction and improvement of its production process has attracted close attention of domestic packaging material manufacturers and packaging and printing companies

development of vacuum aluminized paper in China's packaging industry

vacuum aluminized paper (or aluminized paper, aluminized paper, evaporated paper) is a new green packaging material that has been more and more widely used in the packaging industry since the 1980s. Because of its noble and beautiful metal texture, stable and reliable printing performance and degradable and recyclable environmental protection properties, it is more and more loved by people

since 1992, vacuum sprayed aluminum waterproof wine label paper has entered China's beer bottle sticker packaging market; Since 1993, vacuum sprayed aluminum (gray bottom) paperboard has been used in domestic Baijiu, tea, cosmetics, food and gift packaging markets; Since 1997, vacuum sprayed aluminum cards have entered the external packaging market of domestic cigarettes, gradually replacing the traditional aluminum foil cards, laminated cards and other non environmental protection packaging materials; In 2000, vacuum aluminized lining paper began to enter the graphene material developed by Professor Chen Yongsheng's team and entered China's cigarette packaging market. Some experts predict that at the beginning of the 21st century, vacuum aluminum spray paper (card) will become the darling of China's packaging industry, and the market prospect is very optimistic

production process of vacuum aluminum spraying paper

vacuum aluminum spraying paper can be divided into direct method (paper surface aluminum spraying) and transfer method (film surface aluminum spraying) according to the production process. The direct method is to put the paper directly into the vacuum aluminum spraying machine for aluminum spraying. This method is limited to thin paper aluminum spraying. The transfer method takes pet and BOPP films as the transfer substrate, and after coating and coloring, aluminum spraying, compounding, stripping and other processes, the aluminum spraying molecular layer with metallic luster is transferred to the surface of paper or paperboard through adhesive action. This method can produce more than 40 ~ 450 grams of paper or paperboard. Compared with the direct method, the transfer method has the following outstanding characteristics: first, it can produce paper or paperboard of any thickness by fully abiding by Hooke's law; Second, it can make full use of the flatness of PET film to make the paper metal luster brighter; Third, it can produce laser anti-counterfeiting vacuum aluminum spray paper or paperboard with any patterns and words
