Engineering printed non-woven bags

The printing on polypropylene material has posed many challenges for suppliers. Most providers of non-woven bags are used the technique "print screen", also known as "screen print" (screen print) on the non-woven bags. This technique can reduce costs and increase speed without affecting the results.
However, this printing technique on canvas products requires good skills and techniques necessary to achieve a format desired results. Screen printing technique focuses on three main components: the ink coverage, the number of colors to be printed onto the surface, ensuring dry after printing ink onto the surface of a cloth bag.
Screen printing technique used to print non-woven bags.

 To achieve the best coverage on non-woven material requires the printing must have been carefully experience necessary power. It all started with the same inks, the same used on the T-shirt printing film unlike on non-woven bags. The difference between these types of materials (textile and non-woven fabric between, solid and foam) should be different ink components. So look for a supplier can give you good inks have the best ink coverage, in particular white ink on the dark colors like black, red, hunter green, navy blue roya. The selection of suppliers is to be mentioned first to ink supplier with high ink coverage instead of having to consider the color of the fabric.
The difficulty increases when trying to print multiple colors. Because the material is actually plastic, and between the turns in for the different color should be heat drying, making fabrics shrink. So cannot have two non-woven bags with a size shrinks when heat drying ink between the color (the color ink to avoid drying the adhesive screen printing ink color), and color change significantly on canvas consolidated nonwoven is a real challenge, which led to a large amount of damage caused by the drying heat even change color on print or drying temperature is too high causing distortion sided printing.
