Branded ecommerce mailer boxes built around the unboxing experience.
Create a custom ear-lock corrugated mailer for branded ecommerce presentation and product unboxing. UPG manufactures the approved mailer with exterior or interior print, custom inserts, and selected finish options for brands worldwide.

What buyers should know first.
A branded ecommerce mailer is an ear-lock corrugated presentation box developed around the product, artwork, and intended unboxing experience. UPG's offer is custom mailer packaging—not regular shipping cartons, master cartons, or RSC cases—and delivery requirements are reviewed per project.
Where ecommerce mailers fit best.
Start with the campaign or program goal, then develop the mailer around the products, presentation, quantity, and destination.
Branded direct-to-customer presentation
Product launches sold through ecommerce
Giftable online orders
Curated multi-product orders
Shape the brief before the artwork.
A clear product and presentation plan helps the structure, insert, and artwork move in the same direction.
Start with the product
Share the dimensions, quantity per box, and intended arrangement so the ear-lock mailer can be developed around the actual packout.
Plan the unboxing surfaces
Decide how exterior branding, interior messaging, and any insert should work together before final artwork begins.
Confirm the project boundary
Transport and delivery requirements are reviewed for the specific project. UPG does not offer standard RSC, master, or regular shipping cartons.
Coordinate the box, print, and product arrangement.
These options are reviewed against the approved ear-lock structure, project quantity, and presentation goal.
