Vacuum aluminum spray 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 film as the transfer substrate, and is coated, colored, sprayed, compounded, and peeled to make the metallized aluminum spray molecular layer transfer to the surface of the paper or paperboard through adhesive. . 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 cardboard; Second, can make full use of the flatness of the pet film to make the paper more metallic luster; Third, you can produce any pattern of radiant , 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 (according to the US fda standard). 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, meets environmental protection requirements, and 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. Vacuum spray aluminum paper with less aluminum, good degradability, can save production costs, while not causing environmental pollution, is environmentally friendly green packaging materials, aluminum foil composite board is an alternative upgrade packaging materials. Aluminum spray paper is widely used in tobacco, wine, bottle stickers, tea, food, cosmetics due to good gloss and smoothness, good flexibility, high aluminum spray fastness, and good printing performance and mechanical processing performance. , 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. Nowadays, more and more well-known enterprises have realized and started to apply this new packaging material to high-end packaging such as cigarette cases, gifts, and alcohol, which will certainly bring new development to the Chinese packaging industry.
