Paper Mailer GSM Guide: What Buyers Should Check Before Bulk Ordering
GSM is usually the first material figure on a paper mailer quotation, and for many packaging buyers it quietly becomes the only one that gets compared. Supplier A quotes 100 GSM.

Digital Proof vs Physical Sample for Custom Mailers: What Buyers Should Check

Paper Mailer Size Guide: How to Choose the Right Size
A common paper mailer sizing mistake happens at the measuring stage, not the ordering stage. A buyer measures the product lying flat on a desk, finds a listed mailer size that looks slightly larger, and orders. The mailer then fits — technically. But the packing station has to work at it: the product goes in […]
