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.

Film Lamination and UV Coating

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.【Thermal Lamination Machine 】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, 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, 【 Film Lamination Machine 】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.

Short Introduction of Thermal Film Laminating Machine

Such kind of laminating equipment does not need adhesive heating and drying system, the laminating process greatly simplifies the laminating process, and the operation is very convenient.

The pre-coated film structure is composed of a substrate and a glue layer. The substrate is usually a PET film and a BOPP film. From the viewpoint of material cost and processing technology, most of the pre-coated film substrates are made of BOPP film and have a thickness of 12-20 micrometers. The thickness is 5-15 microns. [ Automatic Thermal Lamination Machine ] According to different processing equipment and process conditions, different thicknesses of glue layer are selected, and the glue layer is divided into hot melt adhesive and organic polymer low temperature resin. The difference between the two is that the hot melt adhesive is made by blending and modifying several materials of the main adhesive resin, the tackifier and the modifier, and the organic polymer resin is a single polymer low temperature copolymer.

Problems probably occurred during lamination process

Blistering

1. The printed ink layer is not dry. It should be hot pressed and then glued; delay the filming time and make it dry thoroughly.
2. The printed ink layer is too thick. The amount of adhesive applied should be increased to increase the pressure and compound temperature.
3. The drying temperature is too high and the surface of the adhesive is crusted. Should reduce the drying temperature
4. The surface temperature of the composite roll is too high. The composite roll temperature should be lowered.
5. The film has wrinkles or slack, and the film is uneven or curled. [ Lamination Machine Manufacturer ] The film should be replaced and the tension adjusted.
6. There are dust impurities on the surface of the film. It should be cleared in time.

In this machine, the film is formed once, the glue has been applied to the consumables, the glue is melted by heating when the film is coated, and the film is bonded to the printed matter by pressure. This type of laminating equipment is cheap, easy to operate, and does not generate harmful gases during operation. [ Film Lamination Machine ] It is a trend in the development of laminating 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. The main coating technology in the domestic printing industry. The disadvantage is that this 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), the print with silicone oil is difficult to cover Membrane and the like. Widely used in short-run printing, digital fast printing industry.

The pre-coating laminator is a special device that combines printed matter with pre-coated plastic.[ Thermal Lamination Machine ] Compared with the coating type laminating machine, the biggest feature is that there is no coating and drying part, so the laminating machine is compact in structure, small in size, low in cost and easy to operate, with stable product quality.

The method of solving paper and plastic film separation

Analysis of the reasons that affect the separation of paper and plastic film

[ Thermal Film Lamination Machine] 

The reason for the influence of paper-plastic detachment, the smoothness, uniformity, water content of the paper, the performance of the plastic film, the thickness of the printed ink layer, the amount of auxiliary materials, the temperature and pressure during the paper-plastic composite, and the hygienic condition of the production environment And temperature, relative humidity, etc. will have a certain impact on the final result of paper-plastic composite!

[ Lamination Machine Manufacturer ]

The method of solving paper and plastic film separation:

1

The ink layer of the ink is too thick, causing penetration and diffusion of the adhesive, causing the paper to detach. The treatment is to increase the amount of adhesive applied and to increase the pressure.

2

When the ink layer is not dried or is not dried, the component of the residual solvent in the ink layer weakens the adhesive force to form a paper-like detachment. The treatment method is to re-compound after the product ink is dried.

3

The residual powder on the surface of the printed matter also hinders the adhesion of the paper to the plastic film to form a paper-plastic release. The treatment method is to mechanically and manually erase the powder on the surface of the printed matter and then recombine.

4

The operation process is not standardized, the pressure is too small, and the machine speed is fast, which causes the paper to detach. The treatment method is strictly in accordance with the process specification, and the pressure of the film is appropriately increased to reduce the machine speed.[ double side lamination machine]

5

The adhesive is absorbed by the paper and the printing ink, and the paper is detached due to insufficient coating amount. The adhesive should be re-formulated and the amount of glue applied should be determined according to the manufacturer's requirements.

6

The corona treatment of the surface of the plastic film is insufficient or exceeds the service period, so that the paper is separated from the failure of the treated surface. The plastic substrate should be corona or renewed in accordance with the corona standard of the film coating.

7

When a one-component adhesive is used, the paper-plastic detachment due to insufficient air humidity should be artificially humidified according to the humidity requirements of the one-component adhesive processing process.

8

Ensure that the adhesive is kept and used according to the manufacturer's requirements during the warranty period. If the automatic mixer is in good condition, the ratio is accurate, uniform and sufficient.
