Difference between dumb film and bright film on packaging box

Generally, two kinds of film covering processes, bright film or dumb film, are used to improve the texture of finished products. Some also use local film covering to meet the needs of printing. So, what is the difference between bright film and dumb film? Let's get to know.

Bright film is also called light film: it can be seen from the color of the surface that the bright film is a bright surface; Transparent and bright after coating.

Dumb film: it can be seen from the color of the surface that the dumb film is a foggy surface; Matte frosted matte surface after coating; General users use flat paper materials, such as business cards, books, picture albums, posters, color boxes and other products. Peritoneum can not be used for local peritoneum. If you need to achieve local peritoneum effect, you can use other processes, such as UV, oil, etc! At the same time, there are other transparent films made of PVC, which are generally less mass produced and rarely used by users.

The bright film can be effectively separated from the surface of the printed matter. The surface of the album after the bright film will be very bright and glossy.

The surface effect of the dumb film is layer fog. The reason for this state is that the matte frosting is used in the process of coating, so it looks more artistic. And it will feel concave convex, not as smooth as the light film.

It is understood that BOPP film is often used in the printing process, and its film composition is BOPP + EVA double-layer composite film. Both bright film and dumb film will be applied to this material, but the later operation process is different. However, it will not be too complicated. Enterprises can also choose with or without adhesive layer according to their own needs. The adhesive layer can effectively ensure the durability of the album. In the long run, it can save costs for enterprises.

In addition to the bright film and dumb film, other processes can also be used, such as UV glazing, bronzing and silver ironing. UV glazing can make the printed matter more durable, and bronzing process can effectively improve the sense of luxury of the printed matter, but the price will be relatively expensive. If enterprises have no special needs, the use of bright film and dumb film technology can effectively improve the texture of the album.
