6x9 Brown Kraft Self Seal Envelopes 50 Pack

50-Pack Self-Seal Kraft Envelopes

This pack contains fifty brown kraft envelopes measuring six by nine inches with a self-adhesive closure. They are intended for anyone who regularly mails letters, invoices, photos or invitations and wants a quick, moisture-free way to seal each item. The peel-and-seal strip removes the need for licking or tape during high-volume mailing tasks.

Capacity for bulk mailing and storage

Fifty envelopes provide enough supply for routine office correspondence, school mail-outs or household billing cycles without frequent re-ordering. The kraft paper construction resists tearing during handling and keeps contents opaque, so sensitive documents stay private. The pack runs out when mailing volume exceeds fifty pieces or when larger documents require a bigger envelope format.

Practical limits of the peel-and-seal format

The self-adhesive strip bonds securely to the kraft flap but cannot be reopened cleanly once pressed, so items must be finalised before sealing. The envelopes accept laser and inkjet printing for addresses or graphics, yet heavy ink coverage may increase drying time. They are not padded, so fragile objects need separate protection before insertion.
