I would like to ask what is the difference between cold film and timely paste?

Paste in time: The scotch tape used in peacetime is similar, but it is very wide and has various colors. You can carve the outline of words on it with a machine similar to a printer. You can dig out the words and stick them on the glass with the glue (self-adhesive) at the back, and so on. Most shops and restaurants use that thing to "welcome" glass doors. Cold surface forming and cold mounting is to cover a layer of cold mounting film on pictures and photos by using cold mounting technology. Smaller photos or pictures can be pasted with refrigeration film by hand. If the object to be coated is large, you need to use a cold mounting machine. Cold-mounted film is made of transparent PVC through adhesive backing. According to the texture of the film surface, it can be divided into bright film, matte film and protective film with special texture. Optical film and dumb film are widely used in advertising production. Use cold mounting machine and other equipment to mount the cold mounting film on the photo printed picture to prevent the picture (printed surface) from being scratched, polluted or damp, thus protecting the picture. It can be used to mount wedding photography, posters, indoor exhibition board advertisements, engineering and garden renderings, advertising demonstration drawings, commercial and civil interior decoration, commercial document covers, digital photo albums, greeting cards, charts, photo quality brochures, banners, hanging frames and other pictures.
