Introduction to the production process of non-woven bags

1、 Hot pressing process
Hot pressing process is one of the commonly used techniques for making non-woven bags. This process places non-woven fabric material in a mold and then heats and presses it into shape. The hot pressing process can produce non-woven bags that are flat, have high flatness, and have a complete range of sizes and specifications.
2、 Flexible printing
Flexible printing is a commonly used printing process and is also suitable for making non-woven bags. The process flow includes layout production, printing plate production, ink blending, printing, air drying and other links. The printed non-woven bags have bright colors and strong color layering.
3、 Heat transfer printing process
Heat transfer printing is another printing process for non-woven bags, with a relatively simple process flow. This process uses a special type of paper to print patterns on, and then transfers them to non-woven bags through high-temperature heat transfer. The non-woven bag produced has clear patterns, bright colors, and high smoothness.
4、 Cold transfer printing process
Cold transfer printing corresponds to heat transfer printing and is also a process for printing non-woven bags. Unlike heat transfer printing, cold transfer printing involves placing non-woven bags on a special printing machine and printing patterns without heating. Cold transfer printing technology is suitable for a wider range of materials, and the selection of colors for the patterns that need to be printed is also more flexible.
5、 Cutting and sewing process
The cutting and sewing process of non-woven bags is relatively simple. Firstly, cut according to the size specifications of the bag, and then sew the four corners of the bag and the pockets together. When sewing, the stability and firmness of the sewing thread should be maintained to ensure the quality of the bag.
There are various production processes for non-woven bags that complement each other and are suitable for different job requirements. Non woven shopping bags are environmentally friendly and practical, and are extremely popular choices in mass shopping.
