Laminating machine is often used in life. Laminating is to apply adhesive to the plastic film and combine it with the printed matter that uses paper as the substrate. After being pressed together by the rubber roller and heating roller, the paper is formed One product.
        We need to pay attention to the following issues when operating the laminating machine:
        1. There are two kinds of films used in laminating machine and automatic laminating machine: sub-film and bright film. The effect of sub-film is like matte, which has more grades. The effect of bright film is obvious and intuitive, and it has a reflective effect. Choosing different membranes has different effects, which should be freely selected according to your needs.
        2. There are different types of laminating machines, including automatic laminating machines, small laminating machines, pearl cotton laminating machines, pre-coating laminating machines, etc., which should be selected according to production needs.
        3. The laminating machine is best to laminating on both sides at the same time, so that it looks more smooth, has stiffness, and does not curl.

        The conventional automatic laminating machine technology on the market adopts the method of laminating with glue, and the automatic laminating method of the automatic laminating machine is different. The PE film with high pressure polyethylene as the main material is used. After the special treatment of the film is stopped, the PE film can be hot-melted on the color printing paper. After being processed by the automatic laminating machine, it will not bubble when it is rubbed hard, and can withstand high temperatures of about 20 to 120 degrees. In the process of non-glue automatic laminating, a layer of auxiliary materials is placed between the heating roller and the PE film, and passes through the automatic laminating machine together, and then the automatic laminating products are removed from the auxiliary materials. Due to the different materials used, the same kind of PE film can make light film, matt or other effects. First of all, high-pressure polyethylene blow molding PE film as the main material, that is because of its easy to obtain hot melt and plasticity.
        The advantages of fully automatic laminating technology are obvious
        First, if he does not use glue, the cost will be reduced a lot, and it is obviously reduced. Especially for the matt film and the laser film, the cost is basically reduced by about 10%.
        The second is that he is absolutely safe and environmentally friendly. In the past, those easily volatile harmful gases were very harmful to the human body during use. At the same time, after experiments, the product was placed in a 5% caustic soda solution at 80 ° C. With light agitation, the self-adhesive indentation will show the phenomenon of separation of the film and the paper. The film floats up and the paper sinks, which is easy to recycle.
        Third, due to the automatic laminating of the glue, the glue layer is 0.002 ～ 0.003mm after the initial drying, so the powder on the printing paper will appear to be uncompressed, and the product will be uncompacted. snowflake". But the automatic lamination without glue will not, because the film used in this technology is 0.017 ~ 0.02mm thick, and it becomes this thickness of glue in its hot melt state, so it can be used casually with less than half the pressure. No "snowflake" is produced, so there is no need to dust.

        We all know that the service life of product equipment is a way for us to save costs. The longer the service period, the longer the time to update the equipment, which can effectively save costs. So how is the life of the automatic laminating machine used longer?
        The laminating machine is a machine that combines paper documents with plastics; the key to the longevity of the machine lies in the usual correct operation and maintenance. The accuracy of the automatic laminator is very high, especially the surface accuracy and shopping degree of each roller. Once the slightest streaks, cracks, scratches, obscuration, or a slight roundabout deformation. All will affect the processing quality of the product, even not working properly. Therefore, it is very important to protect the automatic laminator carefully and carefully. Here are some knowledge. If you want to use the automatic laminating machine for a long time, you should always check the oil pipes, valves and cylinder plugs of the hydraulic system for oil leakage, and often check whether there is rubber or grease on the rubber roller. Scrub the glue and dust on the roller in time. The grounding of the machine and the insulation of electrical appliances should be ensured. The transmission parts and sliding surfaces of the machine should be regularly lubricated to ensure that the machine is in a good lubrication state. A comprehensive inspection of the machine should be carried out every year to find problems and solve problems in time In order to avoid more serious damage to the machine.

        Instant coating is a process that uses instant coating film laminating machine to immediately stick the film with glue to carry out paper-plastic compounding. Next, let's take a look at the benefits of the instant film laminating machine.
        Benefits of Instant Laminating Machine
        1. Use instant film as the cover to protect the paper. After laminating, the service life of the cover (or the surface of the printed product) can be extended, especially for students' textbooks, so the amount of use is increasing.
        2. Imprints are not easily destroyed. After being coated with a ready-to-use film, it can increase the color effect and protect the color printed graphics without being worn. This is conducive to the publishing house editors to make various art designs on the cover or printed surface according to their needs, so it also promotes the increase in usage.
        3. Improving the production of coating film. The cost of making ready-to-coated film in lamination is low, easy to get started, and profitable, and enterprises can benefit.
        The above three points make the instant coating film "hot", but the quality problems of the instant coating film and the impact on the binding quality are rarely paid attention to.

        Instant-coated film is a process of paper-plastic lamination using instant-coated laminating machine to immediately stick film with glue. It mainly consists of a coating film processing plant or a processing workshop, where the roll plastic film is coated with an adhesive as required, dried (slightly) compounded, and after pressure, the paper film is adhered together to form a coated product. That is, there are two types of coating equipment, automatic and semi-automatic, and the basic working principle is the same.
        The process flow of the instant laminating machine mainly includes unwinding → sizing and coating → drying → compounding → slitting → finished product accumulation.
