What type of paper is used to print scratch cards? What materials are employed?
Common materials for anti-counterfeiting scratch cards include coated paper (157g, 200g, 250g, etc.), white cardstock, adhesive labels, and PVC. The most frequently used are 250g coated paper and adhesive labels. Coated paper has a glossy surface suitable for double-sided printing, while white cardstock is glossy on the front and only suitable for printing simple content on the back. PVC is less commonly used due to its higher cost.
