The effect of automatic laminating machine process:
1. Overlay the protective film on the picture to improve the strength of the picture and the wear resistance of the surface.
2. Isolate the picture from the outside air to prevent deformation and cracking caused by corrosion, humidity, and drying of corrosive gases in the atmosphere, fading and discoloration caused by rain erosion and ultraviolet radiation, and keep the bright color of the picture screen enduring, Extend the life of picture display.
3. Paste the picture on the display board or fabric to make a hanging advertising picture.
4. Press a special mask or sheet on the picture to form a picture with special artistic effects such as bright light, matt, oil painting, virtual and three-dimensional.
Classification of laminating methods of automatic laminating machine:
The coating process completed with various materials and equipment is divided into several categories according to the temperature and use of the raw materials (consumables) used. The following categories are introduced.
Cold mounting: The method of mounting the protective film on the surface of the picture by cold pressing at normal temperature is called cold mounting. There are single-sided mounting and double-sided mounting. In the operation method, there are also manual peeling and self-releasing membrane mounting. The cold mounting process has the characteristics of simple operation, good effect and low cost. At present, it is widely used in the post-production of advertising light boxes, engineering drawings and wedding photography.
Automatic laminating machine hot mounting: the mounting method of the dedicated hot film on equipment heated to a certain temperature (about 100-180 °C) is called hot mounting, which can be divided into single-sided hot mounting and double-sided hot mounting. It has good light permeability and water resistance, good heat resistance and strong hardness. It is suitable for post-production of advertising pictures based on lights or other occasions. However, hot laminating equipment and consumables are more expensive, complicated to operate, consume more energy, and cost more.
Similar to hot mounting, but generally miniaturized. At present, the largest specification plastic packaging equipment on the market is 24 inches, which is packaged by special plastic film heating. It is mainly used for packaging of documents, small-size pictures or documents.
Automatic laminating machine vacuum laminating. It is to use a special vacuum laminating machine to evacuate the film and the painting and set it at a certain temperature to complete the laminating. The operation method is complicated, the cost is high and the picture size is limited, but the mounting quality is very high and the picture texture is strong, which is suitable for photos.

Fully automatic laminating machine vacuum laminating is to use a special vacuum laminating machine to evacuate the film and the painting and set it at a certain temperature to complete the laminating. The operation method is complicated, the cost is high and the picture size is limited, but the mounting quality is very high and the picture texture is strong, which is suitable for photos.

The laminating process of the automatic laminating machine refers to the whole process of laminating pictures and photos, including film selection, film making, and cutting. Mainly used for the post-production of advertising pictures, artistic photos and wedding photos. The film-covered pictures are highly anti-corrosive, waterproof, dust-proof, wrinkle-resistant and anti-ultraviolet erosion, which can produce a strong three-dimensional sense and artistic appeal. So what should we do before the laminating process of the automatic laminator?
Inspection work before the automatic laminating machine starts:
1. Detection before starting the automatic laminator ⑴ Confirm whether the machine is in a safe state.
2. Film transport adjustment to make the film tension even to adapt to the film transport tension.
3. Check whether the gap between the glue roller and the glue is parallel.
4. Check the temperature of the heating roller to avoid inaccurate thermometer.
5. The pressure that the pressure gauge must reach, otherwise the pressure will affect the product.
6. Clean the sundries on the rubber roller, so as not to cause waste in the finished product.
After the automatic laminating machine completes the preparation work, close the main power switch, turn on the heating cylinder and the motor, then turn on the oil pump, adjust the flow of the laminating glue, and adjust the parallelism between the rollers. Adjust the measuring position of the paper on the feeding table, apply the film-coated glue, and turn on the drying tunnel for heating. After testing several sheets of film, adjust the heating temperature, pressure and air intake of the heating roller again until the effect is good, and then start normal work.

The laminating machine manufacturer briefly analyzes the pre-coated film. This process does not require a binder heating and drying system, which greatly simplifies the laminating process, and the operation is very convenient. It can be turned on at any time, and the production flexibility is large, and there is no solvent odor. No environmental pollution, more importantly, it can completely avoid bubbles, delamination and other failures. Its finished products have extremely high transparency and have broad application prospects and promotion value.
Brief analysis of the laminating machine manufacturers. The structure of the pre-coated film is composed of a substrate and an adhesive layer. The substrate is usually PET and BOPP film. From the perspective of material cost and processing technology, most pre-coated film substrates use BOPP film with a thickness of 12 -20 microns, the thickness of the glue layer is 5-15 microns. According to different processing equipment and process conditions, different thicknesses of adhesive layer are selected. The adhesive layer is divided into hot melt adhesive and organic polymer low temperature resin. The difference between the two is that hot-melt adhesives are made by blending and modifying several materials of the main tackifier resin, tackifier and modifier, while the organic polymer resin is a single polymer low-temperature copolymer.
Laminating machine manufacturers stated that due to limitations in technology, production equipment, and raw materials, pre-coating films (mostly hot-melt adhesives) produced by domestic equipment still have quality defects. Because there are production processes that rely on a process similar to that of coating the film, the colloid is dissolved with an organic solvent, and the roller is coated on the substrate film with a concave anilox roller, so there is insufficient solvent evaporation, and an odor occurs during operation. After coating, the solvent evaporates and the surface is prone to blistering. At the same time, because the hot-melt adhesive is blended with several kinds of polymer materials, during use, poor temperature control will cause degradation and cross-linking of the polymer in the hot-melt adhesive, resulting in poor coating surface. Some pre-coated film colloids are easy to adhere to the outer surface of the substrate, resulting in poor winding. Since the adhesive layer is thin and the surface is not activated, defects such as insufficient adhesion to the printed matter are likely to occur. Since the hot-melt adhesive is composed of several materials, the transparency after coating is significantly worse than the low-temperature pure resin pre-coating film.
Brief analysis of the laminating machine manufacturers The pre-coating laminating machine is a laminating equipment with the least investment and the best effect. It is because the pre-coating laminating machine uses an environmentally friendly laminating process, and the operation is simple and the investment is small. It is easy to use. Whether it is mass production or a small amount of laminating, it can be used conveniently. The laminating machine widely used on the market today is a small laminating machine. Therefore, the market potential of the small laminating machine is huge, and the products that use the laminating machine for post-printing processing must have strong market competitiveness. We developed and sold a series of small laminating machines to bring the most affordable, direct and convenient service to our customers.

1. The product to be constructed on the small film laminator must be straight. Handle uneven paper with "ruffled edge" and "tight edge" phenomena. Paper with "lotus edge" can be baked, and paper with "tight edge" can be hung to dry.
2. Be sure to wait for the blot to dry before laminating, otherwise it will cause blistering or hair pulling.
3. Spray as little powder as possible during printing, otherwise it will cause emptying and bubbling at the powder pile. Before spraying the film, the powder should be disposed of. If the number of prints is large, the powder can be hung to dry, and if the number of prints is small, the powder can be manually wiped.
4. Attention should be paid to the direction of the paper strands, especially thick paper, to reduce the curling of the paper due to rolling and stretching.
There is also: the temperature is generally controlled to 40 ~ 60 ℃. Too high a temperature will deform the paper and film, causing the product to curl, but not too low, otherwise it will cause insufficient viscosity. The temperature of coated paper should be slightly lower than that of offset paper.
