The difference lies in the brightness, color and transmittance of the surface.

The surface effect of bright film (light film) is crystal clear, colorful and does not change color for a long time. It has a soft feel and colorful surface colors;

Matt film has a mist-like surface, and after coating, it has a matte-like matte surface;

Extended information:

Specifically, if a protective film is needed for parts that are easy to wear, such as the cover of the product manual and the outer surface of the carton, just after printing. , put a layer on it before folding and cutting. This layer of film must be very transparent, have good toughness, uniform texture, no blisters and bubbles, and the surface is very smooth. It is usually made of polypropylene material, and it is also pre-coated. The thermoplastic polymer adhesive is used to combine with the paper, and the printing factory uses a hot pressure roller to stick it firmly to the paper. The result is a better glossy surface, a thicker texture, and the colors printed on it are protected.

Today's coated paper covers generally need to be laminated, and high-end cartons and handbags, product manuals and corporate brochure covers, wall calendars, and trademarks on clothing... also need to be laminated. You will find that there are two kinds of films, one is as bright as a mirror, and the other is not very reflective. They are called "light film" and "matte film" respectively. The light film is the most transparent and has almost no effect on the ink color, but its reflection is sometimes not very pleasing. The texture of the matte film is thick and stable. It is generally considered to be higher-end than the light film. Its price is also more expensive, but it is like glazing oil. That will affect the ink color. It is not suitable to use matte film for very picky colors, such as the character's skin color or corporate standard colors that are even slightly biased.
