Advantages and Process Applications of Vacuum Aluminized Paper Environmental Protection Materials (2)

The process features are:

1. The process makes full use of the flatness of the PET film to make the surface of the paper smooth, bright and uniform in color and has a stronger metallic texture.
2, the product's printing adaptability, can be used for gravure, offset printing, silk screen, UV printing.
3. The device can produce laser anti-counterfeiting gold and silver cardboard with any pattern and text.
4, the use of transfer method can be used for 80 ~ 350g/m2 of white cardboard, copper plate paper, gray board white paper, cattle cardboard and other production of gold and silver cardboard.
5. The thickness of the aluminum layer of gold and silver cardboard produced by the transfer method is only 0.02 to 0.04 μm (200 to 400 angstroms), which is in line with the environmental protection requirements of various countries in the world and is easy to recycle. Because recycled paper will have an upward trend, it will be the beneficiary of the transfer of aluminized paper.
6. The base film (PET) used in the transfer method can be used repeatedly and the relative cost can be reduced.
7, relatively less investment in equipment, and can better maintain the physical properties of the paper.

Compared with the direct method, the advantage of the transfer method: (1) can produce any thickness of paper or paper. (2) The flatness of the PET film can be fully utilized to make the paper metallic luster brighter. (3) It can produce laser anti-counterfeit vacuum aluminum coated cardboard with various patterns. Disadvantages: (1) There are many processes, and the yield is lower than that of the direct aluminum plating method. The requirements for PET films that require multiple uses are high. (2) The technical requirements for the secondary process of the transfer film are high, and the quality qualification rate control method is limited. (3) There are still some problems in the folding performance of products.

Third, vacuum aluminum coating paper in the application of packaging

1, environmental protection vacuum aluminum plated paper jam

The environment-friendly vacuum aluminum-plated paperboard is produced by the transfer method and has 150 to 400 kinds of grammage specifications. There are various types of ordinary aluminum spray paperboard, gold and silver spray aluminum paperboard and holographic laser paperboard. At present, the paper is widely used in various types of high-end cigarettes, alcohol, food, medicine, cosmetics, gifts and other carton packaging, can also be directly processed into a wave in the form of paper, A wave, B wave, E wave, AB wave Corrugated cardboard packaging products.

2. Environment-friendly aluminum plated paper

Environmentally-friendly aluminum-plated tobacco liners are produced using the direct method. Including environmentally-friendly ordinary vacuum aluminum inner liner paper and direct environmental protection holographic anti-counterfeiting vacuum aluminum inner liner paper. The paper is used in cigarette packs, not only to improve the grade of the goods, increase the added value of the goods, but also can be beneficial to crack down on counterfeit and shoddy goods, effectively protect the interests of manufacturers and safeguard the legitimate rights and interests of consumers. It will also be tobacco. A fundamental revolution in the packaging industry.

3, environment-friendly vacuum aluminum plated paper

Environmentally-friendly vacuum aluminized wine labels are produced using the direct method. About 70g of waterproof paper is processed into two categories, including the direct method of ordinary vacuum aluminum beer label stickers and direct holographic anti-counterfeit beer label stickers. Silver / gold wine standard paper, silver / gold embossed paper, laser / matt wine labels and other specifications. The paper is mainly used for labeling of printable and recyclable glass bottles (including body marks, back labels, neck labels, etc.).

4, environmental protection vacuum aluminum plated paper

Environmentally-friendly vacuum aluminized wrapping paper is produced by direct method and processed from low gram weight packaging paper. Mainly include food packaging paper, gift wrapping paper and other types. The paper is mainly used in the field of food packaging such as chewing gum, chocolate, biscuits, and confectionery. With exquisite styling, beautiful patterns, beautiful colors, and elegant text descriptions, people feel that their inner products are of good quality while also collecting goods. Packaging, merchandise logo, corporate image, advertising and art appreciation.

5, environmental protection vacuum aluminum gift wrapping paper

Environmentally-friendly vacuum aluminum-plated gift wrapping paper is currently the most popular gift wrapping paper in the world. The product is widely used in gift packaging for various festive occasions, such as Spring Festival, Christmas, Birthday, Hershey and other days, and can be processed into a variety of beautiful packaging bags.

6, laser vacuum aluminum anti-counterfeiting wrapping paper

Laser vacuum aluminum sprayed anti-counterfeiting wrapping paper is formed by embossing the laser holographic pattern or text signal onto the surface of aluminum spray paper, and its laser brightness is several times stronger than that of the ordinary laser packaging machine'target=_blank>transparent film's brightness. , And the laser pattern can not wipe. High-tech holographic laser laser anti-counterfeiting materials are mainly used for: anti-counterfeit holographic laser paperboard; anti-counterfeit holographic laser thin paper; anti-counterfeit holographic laser BOPP, BOPET, BOPA, CPP and other plastics; anti-counterfeit holographic laser packaging label materials.

7, stickers (90g or so coated paper) silver / gold paper, silver / gold embossed paper

In order to give the paper an elegant effect, surface embossing can be used, the entire plane pattern makes the label has a special charm. This surface pattern processing makes labels more valuable. Embossing also makes the label more flexible, and its use performance will be better during the labeling process and its subsequent cleaning process.

Fourth, prospect

In short, vacuum aluminum-plated paper not only looks gorgeous, but more importantly, it has anti-counterfeiting and degradability, and 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. Nowadays, more and more well-known enterprises have realized and started to apply vacuum aluminum-plated paper in the packaging fields of beer, tobacco packaging and other industries, which will certainly bring new development opportunities to the Chinese packaging industry.
