Product details
Mailer box structure, board options, and inserts
A mailer box should be sized around the product and the way it will be packed and shipped. Confirm dimensions, weight, protection points, insert needs, board strength, closure, artwork, carton quantity, and destination before the dieline is finalized.
Structure
Corrugated mailer boxes can be reviewed by product fit, board strength, closure style, folding structure, and shipping conditions.
Board and print
Board grade, kraft or white surface, full-color print, inside print, matte or gloss finish, and spot details can be selected by brief.
Inserts and fit
Paperboard inserts, dividers, sleeves, tissue, and other fit details can help organize products and reduce movement during delivery.
Project fit
Confirm product size, weight, quantity per box, packing method, artwork or dieline, destination, and timeline before sampling.
