Products Description
TPU Printed Film Description
Specifications:
Thickness: 0.1-0.2mm (can be customized)
Width: 1370mm (can be customized)
Color: transparent, foggy (any colors can be customized)
Advantages&Applications
TPU film printed products, not only has abrasion resistance, corrosion resistance and other characteristics of TPU, especially suitable use in harsh environment. It usually use polyester based TPU Film shore hardness 85-90A to print, and the printing technology has screen printing, heat transfer printing, digital printing and so on. The surface is excellent and smooth, which is widely used for fashion garments, rainwear, shower curtain, table cloth etc.
Tips for TPU Printed Film
Ink selection
It is better to use TPU ink, physical compatibility.
Corona treatment
Corona treatment was carried out on TPU film to make the dyne value of the surface of TPU film over 38 so that it is suitable for printing. The ideal dyne value is 40-42.
The surface of TPU film was treated with chemical solvent
Chemical solvent treatment on TPU film surface, such as wiping, coating etc
TPU film surface selection
Generally speaking, due to the large surface area of foggy TPU film, compared with bright or smooth TPU film, ink adhesion is good, color fastness is high, easier to print.
