After the printed matter is covered with film, it can improve the quality of the printed matter. Generally, there are two types of film: one is a dumb film and the other is a bright film.
Lamination is the process of covering the surface of printed products with polypropylene and other plastic films, and using adhesives to heat and pressure to bond them together. The coating process is divided into two types: pre-coated film and coated film. The pre-coated film is to pre-coat the adhesive on the plastic film, dry and wind it. Then, in the case of an adhesive, the film can be coated by hot pressing. That is to say, the coating film is to use the adhesive at the same time when coating the film.
The laminating method is divided into "cold lamination" and "hot lamination". "Cold lamination" is to use the pressure of glue and cold lamination machine to bond the photo with the lamination and the backboard; while "hot lamination" is to rely on heat The high temperature and high pressure of the mounting machine complete the mounting of the photos. In comparison, the cost of cold mounting is lower, but the effect of hot mounting is better, and the photo storage time is longer after mounting.
The printed products covered with film are more beautiful, and the grade is also very high. Almost every printed product needs to be covered. In the printing industry of Langfang, printing is almost separate from the laminating factory, so it is more professional.
