When evaluating Vinyl Paper Rolls, you must prioritize material composition (PVC vs. PET), thickness (typically measured in microns or mils), and adhesive type (permanent vs. removable). For signage and advertising, a thickness of 80-100 microns is standard for durability. Ensure the release liner is heavy enough (usually 120g-140g) to prevent curling during high-speed printing. Additionally, verify the surface coating compatibility with specific ink types such as Solvent, Eco-Solvent, UV, or Latex to ensure optimal color vibrancy and ink absorption.
