Both laminator and laminator can be used to laminate products, but the concepts, features, and functions of the two are quite different. The molding process is carried out under certain pressure and high temperature, and it uses high-quality polyester film and hot melt adhesive with good perspective. The laminating machine is a special equipment for paper, board, and laminating film. It can coat the protective film on the picture to improve the strength of the picture and the wear resistance of the surface.
The plastic sealing process consists of a polyester film coated with hot melt glue, and the sealed objects are glued into the plastic film through the processing of a glue machine. Because the processing process is carried out under certain pressure and high temperature, and it uses high-quality polyester film and hot melt adhesive with good perspective. Therefore, it can not only ensure that the plastic-encapsulated objects are not destroyed at normal temperature, but also increase the intuitive effect of the objects. In this process, the technical performance of the glue machine is an important factor to ensure the quality of plastic packaging.
Laminating machines can be divided into two categories: instant-coating laminating machines and pre-coating laminating machines. They are special equipment for paper, board, and laminating films. After being pressurized by the rubber roller and the heating roller, they are combined to form a paper-plastic product.
The thermoplastic of the laminator uses multi-stage temperature control and rolling heating to generate high temperatures to shape the plastic film and data pages. Cold molding is to use adhesive or magnetic plastic packaging film to shape the plastic packaging film and data pages without heating.
The laminating machine can protect the paper by using the coating film as the cover. After covering, the service life of the cover can be extended, especially for students' textbooks, so the dosage is increasing. After being coated with a coating film, it can increase the color effect and protect the color printing graphics and texts without causing them to be worn. This is conducive to publishing houses' art editors to make various art designs on the surface of covers or prints according to their needs, and therefore also promotes the increase in usage.
The laminating machine is equipped with non-stop paper feeding device to ensure continuous production. The large-diameter pressing roller is used to effectively increase the production speed and ensure the smooth and bright composite products. The powder removing mechanism combining sweeping powder and pressing powder is adopted to ensure the powder removing effect. The advanced drying tunnel structure ensures that the glue on the film can be dried quickly.
From the perspective of the development process of plastic packaging technology, due to the improvement of the performance of the laminator and the development of various special films, this special processing method will have a great development. For example, the application of cloth pattern film, matte film, and ultra-low temperature film to improve the artistic effect can improve the artistic effect of the original and has great development potential.
