Corrugated mailer envelopes are made from EE-flute, BE-flute, FF-flute, F-flute, E-flute, B-flute Corrugated Board + Coated Paper. The E/B Flute provides superior compression strength and edgewise crush resistance for reliable shipping protection. The envelope flap uses a friction-fit groove design that secures without tape or adhesive. Stored flat when not in use to save warehouse space.
Our corrugated mailer envelopes support up to 10kg depending on the E/B Flute board grade and envelope size. Reinforced corner walls and double-wall construction are available for heavier items like books, shoes, or heavy accessories.
The envelope flap opens and closes along pre-scored grooves with a friction-fit design that holds securely without tape or adhesive. For heavier shipments, self-locking tab options provide additional security. Assembly is quick and requires no tools.
Our corrugated mailer envelope flap is designed for repeated opening and closing without degradation. The friction-fit groove maintains closure integrity through standard shipping handling. For high-vibration or heavy-load shipping, reinforced flap options are available to prevent accidental opening.
