Common questions
Do I need to add padding or stiffeners inside these mailers?
No. The.020 chipboard construction provides inherent rigidity and puncture resistance, protecting flat documents and photos without additional materials. This reduces assembly time and keeps your per-unit shipping cost low.
How does the peel-and-seal closure work?
Simply peel back the strip to expose the self-adhesive seal, press firmly for 2-3 seconds, and your mailer is sealed. The pull-tab tear strip allows customers to open the package easily without tools or damage to contents.
What items work best in this 9 3/4" x 12 1/4" size?
This format accommodates standard documents (8.5" x 11"), photographs, flat apparel, artwork, certificates, and small merchandise. It's ideal for e-commerce brands shipping items that don't require padding but demand professional protection.
Will these mailers reduce my dimensional weight charges?
Yes. Lightweight chipboard construction minimizes overall weight compared to padded alternatives, directly lowering your per-shipment dimensional weight costs, especially valuable for high-volume e-commerce fulfillment.
