What paper and weight should I use for premium shopping bags?

A common choice for premium bags is board of roughly 170–210 gsm with reinforced top and base; heavier is not always better, as very thick board cracks more easily at folds. Decide three things: colour-through edges (PALETTE), touch or sheen (SOFTSKIN, PEARLSKIN, HALO, CHROMA), and load — always make a loaded test bag. VANGLAM weights are confirmed per grade.
