Vacuum aluminum spray paper (or aluminum spray paper, aluminized paper, steamed paper) is a new type of green packaging material that is 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 biodegradable and recyclable environmental protection properties, it is more and more popular.
Since 1992, vacuum sprayed aluminum waterproof labels have entered China's beer bottle packaging market; since 1993, vacuum spray aluminum (gray) cardboard has been used in the domestic liquor, tea, cosmetics, food, and gift packaging markets; 1997 Since then, the vacuum spray aluminum card has begun to enter the domestic cigarette packaging market, gradually replacing the traditional aluminum foil cards, laminated cards and other non-environmental packaging materials; in 2000, vacuum spray aluminum liner paper began to enter the Chinese cigarette packaging market. Some experts predict that at the beginning of the 21st century, vacuum aluminum spray paper (card) will become the darling of the packaging industry in China, and the market prospects are very optimistic.
Vacuum spray aluminum paper production process
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. The transfer method uses PET and BOPP films as transfer substrates, and is coated, colored, sprayed, compounded, and peeled to achieve a method of transferring aluminum sprayed molecular layers with metallic luster to the surface of paper or paperboard through adhesive action. . This method can produce more than 40-450 grams of paper or cardboard. Compared with the direct method, the outstanding features of the transfer method: First, it can produce any thickness of paper or paperboard; Second, can make full use of the flatness of the PET film to make the paper more metallic luster; Third, can produce any pattern , any text of laser anti-counterfeit vacuum spray aluminum paper or cardboard.
The vacuum ejected aluminum transfer paperboard has the following advantages over the conventional gold card paper:
1. The raw and auxiliary materials used in aluminum spray paper production are odorless and non-toxic, and meet the requirements of food hygiene (conforming to US FDA standards). Can be widely used in tobacco, wine, bottle stickers, tea, food, cosmetics, handicrafts and other products exquisite packaging, can also be used for construction and decoration materials.
2. Good finish, high smoothness, bright color, bright appearance, strong visual impact, can well improve product packaging grade.
3. Has excellent barrier properties, moisture, antioxidant effect.
4. Excellent printing performance and mechanical processing performance, suitable for gravure, letterpress, offset, flexo, screen printing, embossing, die cutting, and even embossing.
5. It has good degradation recovery, is easy to handle and recycled, and meets environmental protection requirements. It is an essential packaging material for export products. However, aluminum foil composite papers that are widely used in the market today cannot be recycled as aluminum products or recycled as paper.
Due to the complicated production technology of aluminum spray transfer method, high technological content, and large investment in equipment, SMEs are difficult to imitate. At present, domestic Rui'an City Xinxin Packaging Materials Co., Ltd., Jiangsu Daya Packaging Co., Ltd. have mature production technology.
Vacuum spray aluminum paper application
Aluminum sprayed aluminum sheet less, degradation, and can reduce production costs, and will not cause environmental pollution, green packaging materials are environmentally friendly, alternative upgrade aluminum composite paperboard packaging material. Sprayed aluminum sheet because of good smoothness and gloss, good flexibility, high fastness sprayed aluminum layer, good printing properties while the mechanical and processing properties, can be widely used in tobacco, alcohol, bottles paste, tea, food, cosmetics , handicrafts and other products exquisitely packaged, can also be used for construction and decoration materials.
In short, the vacuum sprayed aluminum transfer paper not only looks gorgeous, but more importantly, it has anti-counterfeit and degradability, and it is an environmentally friendly product that conforms to international trends. The product has a wide application area, huge potential market, and can replace imports, so the market outlook is optimistic. Today, a growing number of well-known enterprises have realized this and started the new packaging materials used in packets, gifts, alcohol and other high-end packaging, which will bring new development to the Chinese packaging industry.
