Printing Process of Laminated Nonwoven Bags and Laser Nonwoven Bags
Laminated non-woven bag is a kind of environmental protection bag with better visual effect among non-woven bags. Because this bag can print any photo image on the outside of the bag through the printing process, the effect is real and the color saturation is high. Bring many fashion advertising elements into full expression, just like printing color photos.
The color printing of laminated non-woven bags is now widely used in gravure lamination printing. This lamination process is usually divided into two types, one is a glossy film, which may be called a glossy film, and the other is called a sublaminated film. There is a certain difference in the actual effect of the two kinds of coatings. In addition, the bright film is characterized by relatively high gloss and bright color. We will see the effect of reflection on its surface, and the color looks more colorful and crystal clear. The color persistence is also very long lasting. Another good effect is that it can have radiation protection.
The surface of the non-woven bag covered with sub-film has no reflective effect, and its effect is elegant and noble. But he can't protect against radiation.
These two types of laminations have their own advantages and disadvantages. In terms of price, the cost of sub-film is a little higher than that of bright film, but people who love beauty will still choose a little more bright film. Of course, whether the bright film is still a sub-film still needs to be described by the painter based on the detailed drawing image, depending on the specific needs of the picture to show a better effect.
The printed bright film or sub-film is combined with non-woven fabric by casting or glue coating. The casting is made of environmentally friendly polypropylene heated to a certain temperature and extruded into a quantitative liquid. In general, glue coating is to use environmentally friendly glue to bond the non-woven fabric and the film together. In contrast, the quality of the casting process is better. slightly higher price
