Mechanical function of laminating machine

The laminating machine can be divided into two types: instant coating laminating machine and pre-coating laminating machine. It is a special equipment for paper and film. The coating laminating machine includes gluing, drying and hot pressing. The three parts, which have wide application range and stable and reliable processing performance, are widely used in China. Pre-coated laminating machine, without glue and dry parts, small size, low cost, flexible operation, not only suitable for laminating processing of large-volume printed materials, but also suitable for coating of small batches and scattered printed materials such as automated desktop 【 Film Lamination Machine 】 office systems. Processing is very promising.

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.

Maintenance of laminating machine

The ways to laminate the film

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. 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.【Automatic Laminator】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 precoating film, and It is heated and balanced, so the film that is covered is smooth and bright, 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.【Film Lamination Machine】In order to reduce equipment investment and reduce costs, this type of film is used. There are more machines.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 and Instant film lamination

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. 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.【Roll Laminator Manufacturers】China has only used pre-coated films since 2000, and the market share of pre-coated films in China is still small. Precoat 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.

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. 【Reel to Reel Lamination Machine】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.【Laminating Machine Supplier】It is a brand-new transfer technology that can cope with complex workpieces 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.

Will UV varnishing replace the pre-coated film lamination process ?

The printing technology continues to advance, the printing materials are constantly updated, the influence of various post-press processing conditions on the film is increasing, the printing quality standards and market demand are constantly increasing, which requires the film industry to change according to objective conditions. New quality technical standards for structural adjustment. At the same time, we should also look for other processes that can replace the film in time to reduce the pressure on the environment. In fact, in addition to the film coating process, UV glazing can also play a certain role in protecting and decorating the surface of the printed matter. The two are similar in many functions. Due to the relatively low cost of UV glazing, 【Laminating Machine Supplier】the development is relatively rapid, and the product is very attractive, so it also has a certain market share in some post-press processing fields. Some people who are optimistic about UV glazing technology even believe that this technology can be independently developed instead of laminating technology.

In fact, this is just a wish of people. According to some printing companies that use UV glazing technology, UV glazing applications are mostly partial glazing. Local UV glazing can improve the grade of books, but in most cases, this partial UV glazing process is also This is done after the film is applied, and the previous film coating process must be a solvent-based film. In addition, there is still a lot of deficiencies in UV glazing compared to film coating. Such as UV glazing protection, folding resistance, wear resistance, etc. are not as good as the film, there are limitations in many areas, 【Lamination Machine Manufacturer】 such as packaging boxes; UV glazing also needs to put into printing equipment and UV curing equipment, and the film has Off-the-shelf equipment foundation and mature technology; in addition, some UV varnish will also volatilize odor during the coating process, which will affect the operator.

Today's printing houses and publishing houses pay great attention to this process, and believe that UV glazing can replace the laminating process in book printing. But in general, UV glazing is still limited in many aspects, there are still many problems in the process, and it is impossible to completely replace the laminating process.

Pre-coated Film Lamination is the Developing Trend

In China, I think there are four important reasons for the comprehensive replacement of pre-coated films: The first reason is that after 12 years of development, the whole industry has already recognized the pre-coated film, the pre-coated film is of good quality, and the pre-coated film. Environmental protection, which is recognized by the entire printing industry.

Now everyone knows that the industry is aware of pre-coated film, which is a very important point; the second point is the formation of industrial clusters.【Water Based Lamination Machine 】After 12 years of development, I believe that there are currently 30 manufacturers of pre-coated films in China. The third important factor is the cost reduction due to the improvement of industrial clusters and industrial technology. The original pre-coated film has three sentences, one sentence. It is good quality, one sentence is environmental protection, and one sentence is expensive. Many manufacturers use our products to proof, and do not produce after the completion of the test. Because he costs a lot. But today, the pre-coated film is already not expensive, and the pre-coated film is now flat with the solvent-based water-based film.The reduction in film cost is one reason for the overall replacement of the precoat film. Another important basis is the policy. 【Fully Automatic Lamination Machine 】A series of national policies will play an important role in promoting the development of pre-coated films, especially green printing.

The global market share is like this. According to the statistics of the National Press Center in 2009, the US pre-coated film has reached 95%, Japan has reached 70%, Europe has reached 60%, South Korea has reached 50%, and China in 2009. In April, the pre-coated film only accounted for 10%. China Information Center statistical pre-coating film accounted for 10%, water content accounted for 21%, solvent type accounted for 69%, today the number is greatly reduced, today water includes PUR glue and so on, and today's pre-coated film is not 10% It is also highly developed. This is 2009, because we want authoritative data. 【Automatic Film Laminating Machine 】This standard rose to the national standard in 2010, and it is clear in the standard that there are no contaminated items in the laminating machine. In particular, the signing of the green environmental protection agreement in 2010 will further promote the comprehensive replacement of the pre-coated film.   

Therefore, in order to develop the green and digital development of China's printing, and for the sake of national health, it is necessary to jointly promote the pre-coating film to be a comprehensive replacement for the benefit of the people.
