Partners Brand M1291K Easy-Fold Mailers

The Partners Brand M1291K Easy-Fold Mailers are kraft shipping envelopes supplied in a 50-count bundle. They are designed for businesses and individuals who regularly send flat or slightly bulky items through the post. The self-sealing fold design removes the need for separate tape or glue during packing. Each mailer arrives flat and ready to use straight from the box.

Easy-Fold Self-Seal Design

The integrated fold-over flap creates a secure closure without extra packing materials. This feature reduces packing time per shipment and lowers the consumable cost for tape rolls. The kraft construction provides a writable surface for addresses and handling instructions. The bundle quantity of 50 supports moderate-volume mailing operations without excessive storage demands.

Check Item Dimensions Before Ordering

Verify that your typical contents fit within the mailer's internal depth of one inch. Measure your products to confirm they do not exceed the length and width allowances. Ensure your postage scale and meter can process the finished package thickness. Buyers who need more internal volume or a rigid protective structure should consider alternative packaging styles.

Questions about this item

How many times can the M1291K Easy-Fold Mailer be folded and refolded before the kraft material weakens?

The kraft construction is designed for a single fold-and-seal cycle; repeated folding will fatigue the fibres and compromise the mailer's structural integrity.

What is the first limitation you hit when packing these 12 1/8" x 9 1/8" x 1" mailers continuously for high-volume shipping?

The 1-inch depth restricts contents to flat or slim items; bulky products exceed the internal volume before weight becomes an issue.

Do the M1291K mailers generate dust or static when processed through automated folding equipment all day?

The kraft paper produces minimal paper dust and low static buildup, so inline folders and sealers run cleanly without frequent cleaning stops.
