What Can Be Used On White Block Bags Write On Area

White Block Zipper Locking bags are perfect for easily identifying parts and contents. The white block area accepts markers, pen ink, and rubber stamp.


The white block area on poly bags is great for keeping things organized by simple writing on the bag. Although you can write on the white block panel with virtually anything, some writing utensils are better than others. It is not just white ink on this style of bag.


The white block area on reclosable bags uses a special varnish. This white varnish is akin to a matt color with a rougher, more porous surface. Due to the properties of this special varnish/ink used for white block bags, certain types of writing tools will quickly adhere and dry on the bag, such as a sharpie marker. Other types of writing utensils, such as gel ballpoint pens, will not dry quickly and have a tendency to smear.
