Before You Order

Roll End Tuck Front (RETF) FAQ

Practical answers on choosing the structure, avoiding common problems, and confirming the right specification for your product.

What distinguishes the tuck-front opening in this mailer?

The closure is presented at the front, so its engagement and finger access should be approved as part of the opening experience. Ask for the exact dieline and a folded sample; similar trade names can hide different tab and wall arrangements.

Technical references
How can we avoid damaging the front panel when opening?

Check the gripping area and release motion with a fully packed sample. A front closure that needs excessive pulling may crease the display face. Trial a revised finger opening or tab shape and make sure the opening cue stays visible after labeling.

Technical references
Can a front seal cover our logo?

Map the actual seal or label dimensions onto the closed front panel before placing the logo. Pack and seal a printed mockup using the intended workflow. Check that the customer's opening motion does not immediately tear through information meant to remain legible.

Technical references
What needs checking before the RETF replaces another mailer?

Compare the usable interior, front tuck path and end-wall buildup with the existing pack. Transfer the complete product arrangement into a sample, then test the final shipping configuration. Matching outer dimensions alone does not establish insert fit or equal protection.
