1. Prints with poor flatness are prone to wrinkles when coated, and because of the unevenness of the paper, the adhesive cannot be evenly coated on the paper, resulting in film peeling and blistering.
2. After the product is printed, it should be stored for a period of time to facilitate the evaporation of paper moisture. Otherwise, after the film is laminated, as the moisture evaporates, the paper fibers shrink, which will cause the film to wrinkle.
3. If the surface roughness of the printed matter is too high, it will affect the castability (leveling and spreading) of the adhesive, resulting in uneven coating, and the product surface after coating will produce bright spots or "fogging" with uneven gloss.
4. It is inevitable to use chemical syrup in the printing process, and it is easy to change the surface structure of the paper, so that the adhesive and the paper can not be in good contact, resulting in the product blistering after long-term storage.
5. When the automatic laminator is in the peritoneum, the adhesive layer on the surface of the printed product is dried to the initial dryness, and the thickness is about 0.002mm~0.003mm. Snowy spots.
6. If the ink layer on the surface of the printed matter is too thick or not dry, the adhesive applied by the automatic laminating machine during the lamination cannot penetrate through the pores between the ink layer and the paper to bond, and false bonding will occur, resulting in The finished film foams in a short time.

The principle of laminating by laminating machine is that the plastic film is coated with adhesive to make it and the paper as the printed matter of the substrate, and then pressed together by the rubber roller and the heating roller to form a paper-plastic one product. The printed product after lamination has a thin and transparent plastic film on the surface, which makes the surface smoother and brighter. The laminating machine not only improves the gloss and fastness of the printed product, but also extends the service life of the printed product. At the same time, the plastic film It also plays a protective role in wear resistance, folding resistance, waterproof, antifouling, and chemical resistance.
If a transparent bright film laminating film is used, the printed graphics and text of the laminating product are more vivid and full of three-dimensional sense, which is especially suitable for the packaging of green food and other commodities, which can arouse people's appetite and consumption desire. If a matte film lamination is used, the lamination product will give consumers a noble and elegant feeling. Therefore, the packaging printed matter after laminating can significantly improve the grade and added value of the product packaging.

The difficulties faced by laminating machine manufacturers are more than that. The impact of laminating machinery manufacturers on the laminating machine industry in Dongguan is an unspeakable "pain" for enterprises. Large laminating machine manufacturers and early-stage enterprises testing water and electricity, such as Tongjia Machinery It has been very moist, and the way for SMEs to develop e-commerce is undoubtedly blind.
Transforming the Internet+ is the new way out
"Standing on the tuyere, pigs can fly", Internet+ is no longer a concept. "Standing on the "Internet+" tuyere and following the trend will make China's economy fly." Premier Li Keqiang's statement made "Internet +" becomes the new engine of the national economy. Facing the advent of this brand-new era, how should traditional enterprises do “addition” and take off again?
Such as the change of marketing model, the previous change of the laminating machine from the physical store to the online point, another, under the role of the Internet, the end user’s demand analysis, data collection, etc. will not allow a company to blindly produce, resulting in a backlog of goods , So as to affect the capital chain.
Internet + big data, such as what changes have occurred to the current buying crowd? Purchasing power? We can make use of the interconnected big data to make corresponding adjustments in the design of laminating machines, product positioning, R&D, sales, and publicity.
Internet+ does not simply move the product to online sales, but to let the product design, research and development, and sales to make users feel humanistic care, so that the user's life is completely in a smart life.
Laminating machine Internet + model representative
Laminating machine special search was established in 2011, its positioning free to help users find the cheapest laminating machine supplier, such as laminating machine manufacturers need raw materials, no longer need to spend time to find suppliers, laminating machine special search will pass Its offline information officer provides the manufacturer with information and quotations for the purchaser. The purchaser only needs to select the supplier online, and there is a special search for the laminating machine to find the problem later.
"'Internet+' is not a subversion of Dongguan's laminating machine industry, but transformation and upgrading and optimization and reconstruction. And e-commerce is becoming a new breakthrough under the'Internet+' wind." If the laminating machine manufacturers seize " "Internet +" This is a straw that may be life-saving.

The laminating process of the laminating machine refers to the whole process of laminating pictures and photos, including film selection, film making, and cutting. It is mainly used for the post-production of advertising pictures and wedding photos. Below we introduce the laminating machine The effect of the coating process:
1. Overlay the protective film on the picture to improve the strength of the picture and the wear resistance of the surface.
2. The laminating machine pastes the pictures on the display board or the cloth surface to make a hanging advertising picture.
3. Isolate the picture from the outside air to prevent the deformation and cracking caused by the dampness, corrosion and drying of the corrosive gas in the atmosphere, the fading and discoloration caused by rain erosion and ultraviolet radiation, and keep the picture picture. The bright color lasts for a long time, extending the life of the picture display.
4. Lay a special mask or sheet on the picture to form a picture with special artistic effects such as bright light, oil painting, matt, virtual and three-dimensional.

(1) Using instant film as the cover can protect the paper. After laminating, the service life of the cover (or the surface of the printed product) can be extended, especially for students' textbooks, so the amount of use is increasing.
(2) Imprints are not easily destroyed. After being coated with a ready-to-use film, it can increase the color effect and protect the color printed graphics without being worn. This is conducive to the publishing house editors to make various art designs on the cover or printed surface according to their needs, so it also promotes the increase in usage.
(3) The production of coating film is beneficial. In the automatic laminating machine, the production cost of the coating film is low, easy to start, and profitable, and the enterprise can benefit.
The failure problems that often occur in laminating machines and how to solve them
1. The machine does not start: the input wire is disconnected, the power cord is reversed, and the voltage is insufficient.
Second, the temperature measurement is not accurate: thermocouple, temperature controller. Whether it is installed incorrectly and damaged.
3. The working vacuum does not come up: the gas path is blocked, the hand valve or the solenoid valve is not closed, the vacuum pump motor belt is loose, and the vacuum gauge is damaged.
4. The main power switch trips: leakage of the input wire on the top of the heating box, leakage of the distribution box, external wires on the equipment, leakage of the motor, etc.
Fifth, the suction film is not in place: the vacuum is not enough, the air leakage, the temperature is not enough, the film is too thin, the workpiece is pasted with other materials, the concave depth of the workpiece exceeds the lift of the film, the suction time is too short, the film is not lifted, the distance between the workpiece Too close.
Sixth, the surface of the returned workpiece has folds and is not smooth or the corners cannot be wrapped: the film is not straightened, the quality of the film is not good, the workpiece is not well polished, the glue is sprayed too much, and the mold below the workpiece is too low.
7. The membrane is pulled down when the suction is not completed: whether the solenoid valve or the hand valve is open.
