Tyvek® Interlinings for Double-Sided Flags, Signs, and Banners

Interlinings made with Tyvek® are often used for double-sided flags, signs, and banners to help prevent show-through from one side of the flag to the other. Tyvek® is extremely lightweight, tear-resistant and highly water resistant, has excellent drapability and is easily sewn. Tyvek® 1443R and Tyvek® 14-S are lighter than traditional blockout interlinings. With its metallized silver coating on one side, Tyvek® 14-S blocks out more light compared to style 1443R.

  • Flexible and fabric-like
  • Partial light blockout
