The hot film of the hot laminating machine relies on the intimate combination with the surface of the paper and is packaged in a roll package. The hot film used by the hot laminator is thinner and softer. The paper after the hot film is not as hard as the plastic film. The paper is still flexible and can be curled. There is no need to worry about over-plastic curling with a laminator, but cold laminators and single-sided hot laminators are prone to warping for thin paper lamination (unless a professional, high-cost anti-roll single-sided is used Hot film), if the paper is curled and then unfolded after cold lamination, bubbles and wrinkles may appear. Single-sided cold lamination is also easy to curl the paper, and the film curling is also used with functions such as temperature and speed adjustment of the hot laminator. There are relationships.
On the one hand, in the field of membranes, we are looking for highly functional membranes in a wide range of industrial fields. The development of new raw material resins, the development of processing technologies such as compounding and lamination are prevalent. However, global issues such as energy saving, from the perspective of the environment, solvent-free membrane technology and the use of energy-saving technology in terms of electron beam irradiation are used in parallel with membrane technology. Film-coated steel sheets are aimed at the industrial field, and are related to IT, optics, automotive, and building decoration. There are other fields with a wide range of uses. Examples of specific content are film production methods, physical properties, durability, other characteristics, etc.

1. Smell: understand the equipment parameters of the hot laminating machine; the machine configuration, the parts used by the hot and cold laminating equipment, and the manufacturer of the parts, etc., which contain many factors, such as whether the machine is domestic or imported, the work used Whether the rubber rollers are the same, etc. Many people will ask how much is a laminator? The answer we get is between thousands and tens of thousands. There are many factors that determine the price of cold laminators and laminators. When buying cold and hot laminating equipment Don't just consider the price.
2. Question: Inquire about the function and applicability of the hot laminating machine equipment, and learn more; Jintu cold and hot laminating machine is a versatile laminating equipment that can be cold-mounted, hot-mounted, and self-rolling back Paper, take pictures by yourself. Especially in the cold laminating work, proper heating of the rubber roller can improve the laminating effect. It can be used as a cold laminator, low temperature cold laminator, and hot laminator. It is widely used in advertising, exhibitions, photo studios, quick printing, etc. Industries that need graphic and frame production.
The temperature and humidity of the laboratory and the storage conditions of the material have a significant impact on the final product, especially during heat-assisted mounting and hot mounting. These cardboards, such as double-coated boards, can absorb moisture in the storage room. Water vapor accumulates inside the mounting plate, which will affect the quality of the mounting, and sometimes the printed pictures will fall off the mounting plate. To avoid this, you can first adapt the mounting board to the mounting and display conditions, and then mount it. (Carpenters also use the same method when installing flooring materials. They first adapt the hardwood flooring materials to room temperature, and then To install). In order to obtain the ideal smoothing effect, you'd better dry the printed pictures and the mounting board in advance, so as to remove excess moisture.

The process of rotary laminating machine is mainly divided into semi-automatic operation and fully automatic operation. Although the specific operations of semi-automatic and full-automatic are somewhat different, the principle is the same: first, the adhesive is applied to the plastic film by a roller coating device, and the film is softened by heating with a hot pressing roller, and then the coating is applied The printed matter of the base material and the film are pressed together to form a paper-plastic integrated film product.
The reason for the vacuum rotary laminating machine is that the surface tension value of the glazing paint is large. The wetting effect of the outer ink layer of the printed matter is not good. The surface tension value should be reduced to improve the wettability of the ink layer of the coating; the solvent in the coating is poorly volatilized, the residual solvent in the coating is high, and the volatilization rate can be changed to high The solvent may make the coating completely dry and then press it; it may also be that the speed of the coating is too fast, the drying temperature is low, the coating is not completely dried, and the solvent is not completely evaporated, you should adjust the coating Process conditions; the ink layer on the surface of the printed matter will also crystallize, which requires effective measures, such as removing the oil on the crystallized surface of the ink layer or performing a roughening treatment to improve the wetting effect of the coating on the ink layer to weaken or Eliminate the adverse effects of ink layer crystallization on glaze coating.

Fully automatic laminating machine manufacturers: The laminating temperature is very important, so the hot laminating machine has better laminating effect than the cold laminating machine. The temperature control of the laminating machine must be appropriate. The amount of printed matter on cold or rainy days should be kept for a period of time. If the temperature If the adjustment is not suitable, the coated product will not shine. When laminating, sometimes there are obvious water droplets or steam on the silicone roller, which is caused by the paper absorbing a lot of moisture. The film laminating temperature of such products must be raised a little bit more. If the film temperature is adjusted too high, it will foam. Therefore, the temperature of the heating steel drum must be controlled according to the characteristics of the product when laminating.
With the development of the advertising industry and the application of digital fast printing technology, many advertising graphic equipment, such as cold laminating equipment used for cover processing, have developed rapidly in the past two years. Laminating machines, "cold laminating" and "hot" "Mounting" is two processing methods of laminating machine. At present, there are several brands of cold laminating equipment currently on the market, and the prices vary greatly. The quality of the product is good or bad. Jintu Laminating Machine reminds that the price is not the only factor for buying a laminating machine. The price of the laminating machine is also variable according to different configurations or working side. Choosing the right cold laminating film machine can be like a Chinese medicine doctor, looking for four steps.

The small laminating machine handles the fundamental problem of the first laminating machine. The laminating machine price is between 1400-1500 yuan, because the internal hot rubber roller is used to press the film and enter the film up and down, which increases the heating time of the pre-coated film, and The heat is balanced, so the film covered is flat, bright and has the same function as the film covered by the advanced film laminator. Only this type of laminator has a heating power of only 500W, although the temperature is adjustable but the speed is fixed, it can press the film 0.7-0.8 meters per minute. Suitable for hand prick film, recipe film, photo film and graphic print film, especially some small printing plants, typing copy shops, hand prick manufacturing companies and photo studios, in order to reduce equipment investment and reduce costs, so choose this type There are more laminators. At present, the market prospect of this type of laminating machine is very good. It can be said that this laminating machine is the most cost-effective.
Laminating is mainly to compound a layer of film on the surface of our printed books and periodicals packaging, so that our printed products are stronger and more beautiful. To put it simply: the laminating film is passed through the unwinding device through a laminating machine, and then the adhesive is applied through a coating tank equipped with adhesive. The solvent type is the coating of the adhesive through the action of glue and solvent, while the water-based type is coated with water-soluble glue. After coating, it is dried, and after drying, it is compounded with paper to complete the coating film. The process of pre-coating film is basically that the pre-coating film is compounded in the factory. Its synthesis is to synthesize five layers: substrate, coating agent, and glue. The glue used is food-grade.
