Supply and Demand Analysis of Aluminized Paper Market and Countermeasures for Industrial Development
Looking at the market for Chinese paper-based aluminized packaging materials, it can generally be divided into three stages. The first phase of the market for aluminized cards (paper) was mainly on beer labels. This part of the market has now reached a stage of steady growth, and it is estimated that it will continue to grow steadily for several years. The second stage started with aluminum-plated cards (paper) and was used extensively for cigarette packaging and other products (such as cell phone boxes, cosmetics, etc.). At present, the aluminum spray paper (card) market is in a rapid growth stage in the second phase and is expected to reach a peak in the next 2-3 years. For example, according to the national 50% gold and silver card (paper) packaged aluminum paper (card) for cigarettes, there are at least 600-700 million boxes, the market size is 3 to 5 billion. The third phase is a period of rapid growth. It is expected that within 3-5 years, another important market for aluminized paper will become a fast-growing period, and its scale will reach a market size of about 2 billion to 2.5 billion.
On the other hand, with the promising prospects for industrial development, the added manufacturing companies have increased rapidly. According to incomplete statistics, no fewer than 30 enterprises have already established or are investing in aluminum-plating projects. Some enterprises are also quite large-scale and have advanced equipment. Some have imported equipment from Germany and Japan and have advanced international standards in the 1990s20 Yutai has an annual production capacity of more than 80 million meters and an output value of more than 300 million yuan.
Industrial Development Countermeasures
1. According to statistics, China has imported more than 300 large-scale composite machines, mainly used for the production of composite gold and silver cardboard (film), composite plain grating (film), composite anti-counterfeit holographic paper (film); The transition of aluminum paper (including transfer type gold and silver cardboard, transfer-type plain-surface grating paper, and transfer-type anti-counterfeiting holographic paper) must solve the problem of the supply source of the transfer film. The technical requirements for the transfer film must not be taken lightly.
The bottom paper should meet the customer's requirements for tensile strength, grammage, moisture, and stretch rate; due to the different physical and chemical properties of the backing paper, various properties of the backing paper must be studied;
In addition to the viscosity of the adhesive layer must be greater than the peeling layer, its formula and process determine whether the product will produce small crystal point and folding resistance; the adhesive is very important for the degree of firmness of the coating on the transferred carrier and should be based on different transfer materials. Selection, they can be water-soluble, solvent-based, hot-melt, thermoset, non-dry, etc., to meet the needs of paper, cardboard, plastic; wood; fabric, glass, metal, leather and other different materials. Even paper, due to its performance differences, has to be changed accordingly. Therefore, at the same time when the transfer film is purchased, the corresponding adhesive must be purchased, and the supplier is required to guarantee the process guidance for producing the qualified transfer paper.
The quality of the transfer film determines whether the plastic layer can be peeled cleanly on the peeling machine, so that the peeling layer has a mirror gloss. The supplier should state that the peeling layer and transparent layer are required:
(1) The peeling paint must be transparent;
(2) Peeling paint is easy to separate from the base film, and the strength of its adhesion to the base film can only guarantee that the paint will not be damaged during the production process before separation;
(3) The peeling paint and aluminum layer have good adhesion;
(4) Stripping coating has excellent printing performance and machining performance, and is suitable for gravure, letterpress, offset, flexo, screen printing, embossing, die cutting, even embossing printing, typesetting printing and offset printing capabilities;
(5) The stripping coating has anti-oxidation and moisture-proof effects on the surface of the aluminized layer;
(6) Peeling paint is easy to apply and easy to dry;
According to the requirements of high temperature, medium temperature and low temperature, and the requirements of mirror, semi-gloss, and matte, the layers have corresponding changes in the formula.
The temperature of the soft press on the molded layer reaches 180 degrees Celsius. After the primed surface grating is pressed, there is no rebound and the shot information is well absorbed. In order to increase folding endurance, in order to make no additional crystal spots and cellulite on the imprinted surface grating, it is necessary to make corresponding changes in the formulations and processes of each layer.
After transferring the series of papers and then printing inks, in order to increase the surface wear resistance and brightness, it is necessary to coat a layer of UV-UV varnish, which brings a disadvantage, the UV-ultraviolet oil coating layer under the irradiation of ultraviolet light rapidly increases the hardness As a result, the ink layer and even the aluminized layer burst. To solve this problem, the supplied transfer film must be improved in the coating design and process to prevent the ink layer or even the aluminized layer from bursting.
2. Purchasing ready-made transfer paper (including transfer type gold and silver paperboard, transfer type plain-surface grating paper, transfer type anti-counterfeiting holographic paper) for qualified cigarette packs and wine boxes is reasonably priced and of high quality (no crystal defects are found in printing. The last process: UV ink layer, no ink explosion) and has the following properties (Aluminized paper should be satisfied):
(1). The raw and auxiliary materials used in the 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.
(6). Both decoration performance and anti-counterfeiting performance must be taken into account.
3. Pay attention to the promotion of the process and equipment for the domestic direct aluminum-plated paper and indirect aluminum plating (transfer method).
