The difference between non-woven bags with film and no film

Some customers asked whether the non-woven bag is screen-printed or laminating? What is the difference between the two? Here, the editor of Jinxiang Packaging will tell you about this issue in detail;

As for which process to choose, it still depends on your needs.

If your requirements are not high and you want to do common types, you can directly choose screen printing. Screen printing can also be color-printed, but it is not recommended to use too many colors.

If you have a lot of color systems for layout design, it is recommended that you choose the lamination type, because the lamination type is printed in color. It can be said that as long as you can design it, we can print it for you.

Let me tell you the difference between non-woven bags with film and no film

Screen printing (without film)

Screen printing refers to the use of silk screen as the plate base, and through the photosensitive plate making method, the screen printing plate with graphics and text is made. Screen printing consists of five elements, screen printing plate, squeegee, ink, printing table and substrate. Printing is carried out by using the basic principle that the mesh of the screen printing plate can pass through the ink, and the mesh of the non-graphic part cannot pass through the ink. When printing, pour ink at one end of the screen printing plate, apply a certain pressure to the ink part on the screen printing plate with a scraper, and at the same time move towards the other end of the screen printing plate at a constant speed, the ink is removed from the graphics and text by the scraper during the movement. Part of the mesh is extruded onto the substrate.

Lamination process

The lamination process is a surface processing process after printing. It is also called post-press plastic, post-press glue or post-press lamination. It refers to using a laminating machine to cover a layer of 0.012-0.020mm on the surface of the printed product. Thick transparent plastic film to form a paper-plastic integrated product processing. Generally speaking, according to the process used, it can be divided into two types: namely coating film and pre-coating film, and according to different film materials, it can be divided into two types: bright film and matt film.

  Summarize

Non-woven bags generally use silk screen printing, which has always been a printing process commonly used by many manufacturers. Generally, it is manual printing and machine printing, which is limited to simple LOGO or text printing.

If it is color photos such as landscapes and people, you must use lamination. The pattern is printed on the OPP film (spectroscopy film, sub-film) by the gravure printing machine, and then the film and the cloth are synthesized by the laminating machine. The film-coated bag has the characteristics of beautiful printing pattern, waterproof and good load-bearing. But at the same time the cost is higher
