Among all kinds of tote bags, non-woven bags are very common, and their frequency is second only to synthetic plastic tote bags and kraft paper bags. The process of making non-woven handbags is not complicated, but the key lies in two links, namely dyeing and printing and bag making. How are non-woven bags printed? Today, let's learn about the principle and operation process of screen printing of non-woven handbags!

Screen printing of non-woven hand straps: principles and elements

Screen printing, referred to as silk screen printing for short, can not only print non-woven handbags, but also handbags made of most materials can be silk printed. The principle behind it is actually very simple: the screen is used as the plate base, and the ink is blocked through the mesh. Some ink will penetrate the printing plate through the mesh, and some will be blocked outside the mesh, so that different patterns can be drawn. Screen printing plates are made first, followed by batch printing of non-woven fabrics. There are five elements in the screen printing process, namely, screen printing plate, scraper, ink, printing table and substrate.

Non-woven handbag screen printing: specific operation process

Before printing, merchants and manufacturers must first determine the specific design scheme, and then the manufacturer can make the base plate according to this scheme, which is the screen printing plate mentioned above. After making a screen printing plate, it needs to go through three processes: printing, developing and drying. The purpose of this is to determine the plate.

With a fixed base plate, manufacturers can print non-woven fabrics in batches, but only one color and one pattern can be used at a time. If the pattern on the surface of the non-woven bag is complicated, it needs to be printed many times. The printed non-woven fabric has not been thoroughly formed, and it will be stitched into a bag that can hold things.

Non-woven tote bag screen printing: advantages and disadvantages

There are three main advantages of silk screen printing process: First, it is suitable for different types of printing materials. We can print ink directly on flat or curved surfaces, regardless of the difference in softness and hardness. Second, it can use different types of inks, such as oil-based ink, water-based ink and resin ink.

However, the silk screen printing process also has shortcomings. If the surface of the substrate is uneven, it is very likely that it will not be able to ink. When performing silk screen printing, only one pattern or color can be printed on the bag at a time. If the design scheme is complicated and many visual elements need to be printed on the bag, then silk screen printing will be very troublesome.
