Frequently Asked Questions
Are these rigid mailers recyclable?
Most of the cardboard rigid mailers in this list are recyclable — look for kraft or paperboard construction and remove any plastic labels or adhesive strips before recycling if required by your local program. Check product descriptions for explicit recycling claims.
Can I ship greeting cards without extra stiffeners?
You can for single-card orders if you choose a stay-flat rigid mailer at 450 GSM or higher, but adding a thin chipboard or cardboard stiffener is an inexpensive way to greatly reduce bending risk, especially for valuable or unprotected cards.
What if the mailer adhesive seems weak?
Adhesive performance can vary by batch. If seals feel weak, reinforce with a strip of packaging tape across the flap or use a small dab of glue. When ordering in bulk, test a few samples to confirm seal strength before committing to a large purchase.
