Lightweight & Space Saving
Poly mailer bags are light and compact, helping reduce packing volume, storage space, and shipping weight for e-commerce parcels.
Self-Adhesive Closure

How to Choose the Right Courier Bags
The right courier bag depends on product size, product weight, privacy requirement, delivery distance, closure type, and branding needs. For soft and lightweight products, a standard self-adhesive poly mailer is usually enough. For branded e-commerce packaging, printed courier bags are a better option.
