20 x 20 x 6" Kraft Jumbo Mailers

These 20 x 20 x 6 inch jumbo kraft easy-fold mailers are built from ECT-32-C single wall corrugated board and feature a self-locking easy-fold construction that assembles without tape. Multi-depth scoring lets operators reduce box depth to match actual product height (1", 2", 4", 6"), trimming dimensional weight charges on every shipment.

The square footprint is well suited for apparel, framed artwork, vinyl records, flat-pack kits, and oversized documents that standard RSC boxes cannot efficiently contain. E-commerce fulfillment centers, retail distributors, and B2B shippers use these mailers where a large square format and adjustable depth are both required in the same package.

Each mailer weighs approximately 0.995 lbs and is finished in natural kraft, which accepts standard shipping labels and direct print without additional surface prep. Mailers are sold in bundles of 20 and ship via parcel carrier.
