Yes, screen printing is a commonly used method for printing on non-woven bags. Non-woven bags are made from non-woven polypropylene fabric, which is a popular choice for reusable bags. Here's a general overview of how screen printing can be applied to non-woven bags:
Design Preparation: Create or obtain the desired design or artwork that you want to print on the non-woven bag. This design can be prepared using graphic design software or hand-drawn and then digitized.
Screen Preparation: Prepare a fine mesh screen by coating it with a light-sensitive emulsion. Once the emulsion is dry, place a stencil of your design on the screen. Expose the screen to light, ensuring that the emulsion hardens where the design is located, while the rest of the emulsion washes away.
Setup and Registration: Secure the non-woven bag onto a printing surface or a specialized screen printing machine. Ensure that the bag is properly aligned for accurate printing. Register the screen by aligning it with the bag's position to ensure that the design is printed correctly.
Ink Application: Apply the desired ink color(s) onto the screen, aligned with the stencil design. Use a squeegee to evenly distribute the ink over the design area, pressing it through the mesh and onto the non-woven fabric.
Printing: Lower the screen onto the non-woven bag, making sure that it is in direct contact with the fabric. Apply even pressure and smoothly move the squeegee across the screen, forcing the ink through the mesh and transferring it onto the bag. Lift the screen carefully to reveal the printed design.
Drying and Curing: Allow the printed non-woven bag to dry and cure according to the specific instructions provided by the ink manufacturer. This typically involves air drying the ink or using heat to cure it, depending on the type of ink used.
Screen printing offers durability and long-lasting results on non-woven bags. However, it's advisable to consult with professional screen printing services or experts for detailed guidance and to ensure optimal results based on your specific requirements.
