New Century Green Packaging Materials - Vacuum Aluminum Spray Transfer Jam

After joining the WTO, the impact on the Chinese packaging market will gradually increase. In this process, although foreign packaging companies are not enough to change the existing structure of China's packaging within 3 to 5 years, this is just an important period for China's packaging market to reshuffle and re-allocate its industrial layout. Domestic packaging companies compete with foreign companies. The fierce competition in the retail terminal market also kicked off. This raises higher requirements for China's packaging industry, and the use of new materials, new equipment, new processes and designs, and anti-counterfeiting measures will become more practical. Environmental issues have become the most important of these issues.
Taking cigarette packaging as an example, in recent years, cigarette packaging in China has developed greatly, and the packaging of some products far exceeds the packaging level of some famous international brands. At the same time, the use of non-degradable aluminum foil, gold and silver cards, mirror paper, packaging films, polypropylene fibers, cable pulls, and other non-environmental materials is increasing. After these products are discarded, it is difficult to recycle them. China is a big consumer of tobacco and alcohol, and it is also a country with relatively poor resources. The number of tobacco and wine packaging that cannot be recycled every year is staggering, which wastes resources and causes environmental pollution. Now Europe and the United States have gradually abandoned the paper-plastic composite technology, replaced by a number of new composite paper products (such as vacuum aluminum spray paperboard).

Vacuum aluminum spray transfer paperboard, commonly known as transfer gold paperboard, this kind of gold paperboard is not only comparable to glass paperboard gloss, but also has a matte color and light color, so the transfer of gold paperboard for its high quality, easier to be recycled The use of such advantages as the international popular environmental protection packaging materials. At present, there are two types of gold paper that are widely used in the domestic packaging industry, printing and composite. The introduction and improvement of the vacuum spray aluminum paperboard as a new type of environmentally friendly packaging material has caused domestic packaging material manufacturers and packaging. The printing company pays close attention.

Development of vacuum spray aluminum paper in China's packaging industry

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, recyclable environmental protection properties, it is more and more popular.

Since 1992, vacuum sprayed aluminum waterproof labels have entered the Chinese beer bottle packaging market; since 1993, vacuum sprayed aluminum (gray) cardboard has been used in 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 aluminum spray liner 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 paper metal luster more bright; Third, 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 (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, 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. 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 spray 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. At present, the main applications are the following:

Smoke cardboard

After being printed on a sprayed aluminum paper board with 230 grams of cigarette packaging white cardboard as a substrate, it can be used as a cigarette package and a cigarette cartridge package. Because the thickness of the aluminum layer of the sprayed aluminum paperboard is only 0.02u, which is one-hundredth of that of the aluminum foil used for the composite paperboard, and the amount of aluminum used is small, it is a packaging material that saves the earth's resources. At the same time as the cigarette packaging, after the discarded, the aluminum layer is oxidized in a short time, will not cause environmental pollution, the waste can be returned to the paper mill for recycling after use.

Wine label paper

The sprayed aluminum label paper made from imported water strong base paper is resistant to water, water and curling. It is mainly used for labeling of printable and recyclable glass bottles (including body marks, back labels, neck labels, etc.). This type of aluminum spray paper has good alkali resistance and lye permeability, good printing performance, bottle labeling performance, and good off-label performance when washing bottles. In order to give the wine label paper an elegant effect, surface embossing can be used. The pattern of the entire plane gives the label a special charm.

Wrapping paper

The use of sprayed aluminum paper for food and pharmaceutical packaging can solve the problem that powdered medicines packed in composite packaging films are not easily pourable due to electrostatic attraction. Aluminum spray paper is divided into low weight (50 grams or less) and high weight (300 grams or more). This type of spray aluminum paper has good aluminum fastness, does not dealuminate when twisted, and has good printing performance. The bottom paper used in the production of aluminum spray paper does not contain fluorescent brighteners, and the chemical materials used are odorless and non-toxic, and conform to the FDA standards. Low-thick aluminum spray paper is mainly used for packaging of candy, chocolate, chewing gum and other products. It not only has the flexibility of paper, but also has the air barrier property of aluminum foil composite paper; the high-gram heavy aluminum packaging paperboard is mainly used for the outer packaging of moon cake box, cosmetics box, toothpaste box, wine box and gift box, exquisite and luxurious. Can enhance product value. At present, Colgate has taken the lead in the industry to use aluminized wrapping paper to make toothpaste boxes.

Laser paper

Laser sprayed aluminum paper (referred to as laser paper) is a laser holographic pattern or text signal is loaded onto the surface of aluminum spray paper by molding, laser paper can actually be classified in the category of wine label paper, cigarette paper and packaging paper . This is proposed separately here because it conforms to the trend of anti-counterfeit packaging and has a good market prospect.

The international packaging industry put forward five comprehensive indicators for anti-counterfeit packaging materials: timeliness, aesthetics, identification, versatility, and economy. Advanced anti-counterfeiting packaging materials must have a high technological content, and the price can be accepted by the market, so that the goods can increase the credibility and profitability of the manufacturer on the basis of eliminating counterfeiting. These five highly demanding comprehensive indicators have been a problem that has plagued the packaging industry for many years. The excellent characteristics of laser anti-counterfeit vacuum ejector paper (card) are extremely close to the above five comprehensive indicators and are an ideal anti-counterfeit packaging. material. The laser brightness of the laser sprayed aluminum transfer paper is several times stronger than that of a conventional laser packaging machine'target=_blank>transparent film, and the laser pattern cannot be erased. Laser spray aluminum transfer paper is very good anti-counterfeiting, not only enhances the brand awareness and the customer's reputation, but also its colorful appearance and high-tech merchandise hologram will create an attractive and eye-catching packaging, so that the Stand out from sales.

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, more and more well-known enterprises have realized and started to apply this new type of packaging materials to high-end packaging such as cigarette cases, gifts, and alcohol, which will certainly bring new development opportunities to the Chinese packaging industry.
