SGS-certified sulfur-free paper protects PCBs, solar wafers, and semiconductor parts from tarnish. Custom sizes for reliable global packaging solutions.

For kraft paper, the GSM can range from very light (50 GSM) to extremely thick (350 GSM). A higher GSM generally indicates a denser, more rigid sheet, while a lower GSM points to a lighter, more flexible paper. For example:  • 50–80 GSM kraft paper is thin and pliable, used for wrapping or lining.  • 100–180 GSM is stronger and more versatile, perfect for packaging and printing.  • 250–350 GSM offers strong support, ideal for rigid boxes or industrial packaging.
