Second, pre-coated

The machine film is formed once, the glue used has been coated with glue, the glue is melted by heating when the film is coated, and the film is bonded to the printed matter by pressure. The filming device is cheap, easy to operate, and is operated.【 Film Lamination Machine 】The generation of no harmful gases is a trend in the development of film. In today's society where environmental protection is increasingly concerned, it is believed that this technology will one day replace the pre-coated film and become the main film-coating technology in the domestic printing industry. The technology is not very mature in China, and there are still some problems to be solved, such as: single-sided film curling (has a single-sided anti-curl machine, but the price is higher), and the printing with silicone oil is difficult to cover. Widely used in short-run printing, digital fast printing industry.

Film Lamination Process

The coating process can be divided into cold (cold pressure) coating, hot (heating) coating and liquid coating according to the heat, pressure and material. Thermal coating technology refers to heating and pre-coating the adhesive on the diaphragm, through which the film is bonded to the printed product; while the cold coating is pressed, directly bonding the film to the printed product by the adhesive. Together. Both methods can produce various special films such as UV protective film, waterproof or anti-friction film. 【Film Lamination Machine 】Recently, there has also been a new technology called "liquid film". Simply use a brush, spray gun, roller or special laminator to apply a film directly on the surface of the product. Although the technical operation is simple and the price is low, it is still not mature.Small laminating machine laminating process.



This type of small laminator was developed to meet the needs of low-to-medium consumers. This kind of small laminating machine solves the fundamental problem of the ordinary laminating machine. The price of the laminating machine is between 1400 and 1500 yuan. Since the film is pressed by the inner hot rubber roller, the film is heated up and down, which increases the heating time of the pre-coating film, and It is heated and balanced, so the film that is covered is smooth and bright, 【 Fully Automatic Lamination Machine 】 and it has the same effect as the film coated by the high-grade laminating machine. Only such a small laminating machine has a heating power of only 500 W. Although the temperature is adjustable, the speed is fixed, and the film can be pressed 0.7-0.8 m per minute. Suitable for business card lamination, recipe film, photo film and graphic print film, especially for small printing houses, typing and copying shops, business card production companies and photo studios. In order to reduce equipment investment and reduce costs, this type of film is used. There are more machines.【 Good Laminating Machine 】At present, the market prospects of such small laminating machines are very good. Many customers who used to use them have later started sales of such laminating machines, and the sales volume is also good. It can be said that this small laminating machine is the most cost-effective. It is easy to use and has obvious effects. It solves the needs of some small end customers and has a great promotion value.

Pre-coated Film Lamination Process

The pre-coating film refers to a process in which a plastic film is sized and re-rolled before being combined with a paper printed product. It is firstly applied to the film by the pre-coated film processing factory according to the size of the specification. The glue is applied to the film for re-rolling, and then combined with the printed matter.The pre-coated film was first used in 1989 and has been widely used in Europe and the United States. It entered Asia around 1996. At the same time as entering Asia, Europe and the United States have announced that it is forbidden to use the film as a pre-coating film.【 Fully Automatic Lamination Machine 】Due to the late use, all the countries in Asia except Japan have used pre-coated films, and other countries (such as China, South Korea, etc.) are in the state of pre-coating and film coating. China has only used pre-coated films since 2000, and the market share of pre-coated films in China is still small.


Pre-coated films have many advantages over instant coatings. If the pollution is reduced, there is no damage to the human body; the quality of the film will not be affected by the different properties of the paper or the color of the ink; the pre-coating film laminating machine is simpler to operate, and the processed image is better; the wrinkles are basically eliminated. , bubbles, shedding and other phenomena. Most notably, this is an environmentally friendly process, and the entire production process is harmless to the human body. 【 Laminating Machine Supplier 】 However, the promotion of pre-coated film in China is still relatively slow. Among them, the cost issue is a big influential factor, which determines the enthusiasm of investors for the pre-coating process. In a recent survey, more than half of the respondents believe that pre-coated products are expensive in terms of price, because pre-coated products are printing consumables, and the cost of printing is a non-negligible problem for printers when selecting consumables. 


In addition, due to the lack of paper and film separation technology in China, pre-coated films cannot be completely called an environmentally friendly process in China. In response to this situation, pre-coated products should reduce costs through mass production, so that market prices are getting closer to the needs of printers. At the same time, the research and development or introduction of the paper membrane separation technology should also attract the attention of relevant departments, in order to achieve environmentally friendly coating and rational development of the laminating process without being able to discard the laminating process. 【 Film Lamination Machine 】It is a brand-new transfer technology that can cope with complex work pieces and is suitable for different materials. It also greatly increases the added value of products due to vivid patterns and vivid colors. This technology is a special chemical treatment film, after printing a certain color pattern, it is sent to the surface of the water, using water pressure to write the pattern evenly on the surface of the product, while the coated film is automatically dissolved, washed and baked. After drying, a layer of transparent protective coating is applied, and the product has a completely different visual effect.

Basic Knowledge for Thermal Film Laminating Machine

The pre-coating film lamination is less polluted than the instant coating film lamination and has no harm to the human body. There is no difference in the nature of the paper and it affects the quality. There is no difference in ink color and it affects the filming effect. There is no effect of using adhesives with vinyl binding. The pre-coated film laminating machine is easy to handle and easy to process.【 Thermal Laminator 】The processed graphics are more beautiful and have a good effect. Basically eliminate wrinkles, bubbles, shedding and so on. It has a wide range of applications and can be used for film processing other than printing.


The pre-coating film refers to a process in which a plastic film is sized and re-rolled before being combined with a paper printed product. It is firstly applied to the film by the pre-coated film processing factory according to the size of the specification. The glue is applied to the film for re-rolling, and then combined with the printed matter.【 Lamination Machine Manufacturer 】The film, that is, the film, is a processing technique in which a plastic film is coated with a binder and the paper print is heated and pressurized to bond it together to form a paper-plastic product. The film-coated printed matter has a thin and transparent plastic film on the surface, and the surface is smoother and brighter, thereby improving the gloss and fastness of the printed matter. The color of the graphic is more vivid, three-dimensional, and waterproof. Anti-fouling, abrasion resistance, folding resistance, chemical corrosion resistance, etc.


The pre-coated film is composed of a substrate and a binder layer, and the substrate is usually a polyester (PET) film and a biaxially oriented polypropylene (BOPP) film. BOPP film has the characteristics of high transparency, good brightness, non-toxic and tasteless, water resistance, heat resistance, low cost and soft texture. It is an ideal material in the film coating process, and its thickness is about 12-20um. Therefore, the material cost From the perspective of processing technology, most of the pre-coated film substrates use BOPP film.【Best Thermal Laminator Machine 】The adhesive layer of the pre-coated film has two types of melt type and solvent volatilization type. According to different processing equipment and process conditions, adhesive layers of different thicknesses are selected, and the thickness of the adhesive layer is generally between 5-15 um. At present, the adhesive layer of the domestic pre-coated film is mainly composed of hot melt adhesive or organic polymer low temperature resin. Hot melt adhesive is made by blending and modifying several main materials such as main adhesive resin, tackifier and conditioner. The organic polymer resin is a single polymer low temperature copolymer. Since the hot melt adhesive is a mixture of several materials, the transparency after coating is significantly lower than that of the low temperature pure resin type pre-coated.


The production process of the solvent volatilization type pre-coated film is similar to the film coating process, and the colloid is dissolved in an organic solvent and then coated on the film substrate, so that the organic solvent may be volatilized incompletely, and the odor may be generated during the film operation. 【 Film Lamination Machine 】The operator causes damage (relative to the coating film coating process, the damage is much smaller), etc., the solvent evaporates after the film is coated, and it is easy to form bubbles on the surface of the printed matter.

Very promising.


The laminating process is a surface processing process after printing, and is also known as post-printing. Post-press silicone or post-printing film refers to a film processing machine that covers a surface of a printed product with a transparent plastic film of 0.012 to 0.020 mm thick to form a paper-plastic product processing technology. The laminating machine is used to complete the laminating process. Generally speaking, according to the process used, it can be divided into two types: the coating film and the pre-coating film. [  Water based Lamination Machine  ] According to the film material, it is divided into two types: a bright film and a matte film. The main problems affecting the laminating process: affecting the health of the operators, there are fire hazards; the paper and film materials after lamination are difficult to recycle, wasting resources.

Film inspection before running the semi-automatic laminating machine

After the semi-automatic laminating machine is adjusted, the pre-processed printed matter is fed into a paper feeding mechanism for lamination, and samples are taken for inspection. Before the film is covered, a small amount of printed matter is used for inspection to avoid a large amount of waste. [  Semi automatic lamination machine  ] After the test is passed, large-scale production can be carried out.


The film inspection method is as follows:
1. 
The semi-automatic laminating machine peels off the corner of the sample film which is completed by the film in the width direction, presses the paper, tears all the width direction, and after all tearing and tearing, if the surface of the printed matter is imprinted with the rubber layer The transfer of the fibers of the paper to the film indicates that the printed matter adheres well to the film and is a qualified product.

2.
Semi-automatic laminating machine put the coated sample into the drying tunnel, baking at 60 ~ 65 degrees Celsius for about 30 minutes, if there is no foaming, no delamination, no wrinkles, is a qualified product. [ Manual Lamination Machine ] The film peeled off after baking should not be separated from the paper.

3. 
The semi-automatic laminating machine takes the sample into cold water for 1 hour and then takes it out. If the plastic film and the printed matter are not separated, it is a good product.

4. 
The semi-automatic laminating machine puts the sample on the creasing machine and presses it. If the concave and convex parts are not delaminated, it is a good product.
