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.

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.

Instant Water-based Film Laminating Machine

Characteristics of instant coated products

Thermal Lamination Machine

(1) It is prone to foaming and film detachment. In large-area solid printing or high humidity working environment, foaming and film removal are particularly serious.
(2) The surface of the product often produces bright spots or fog points with different gloss.
(3) The product is prone to curling. If the pressure is too high when the glue is applied or the temperature is too high during drying, 【 Manual Lamination Machine 】 the curling phenomenon is more serious.
(4) Chemical substances such as organic solvents will volatilize into the atmosphere during filming, causing environmental pollution and even causing fires.


Characteristics of pre-coated film products
(1) The film-forming product using the molten pre-coating film does not exhibit foaming and film peeling, and the product has a long service life.
(2) The film-coated product using the solvent-evaporable pre-coating film may have a large thickness in the printing ink layer, where the folding, die-cutting, and indentation pressures are relatively large, or in a high-temperature environment, the film may be released and foamed. phenomenon.
(3) The solvent-evaporable pre-coating film easily adheres to impurities such as dust during production, 【Film Lamination Machine 】thereby affecting the surface effect of the film-coated product.
(4) The film product is basically free from curling.
It can be seen from the above that the pre-coating film coating process, especially the molten pre-coating film coating process has the advantage that the coating film coating process cannot match, and is an inevitable choice for the future film coating industry.
