Pack of fifty self-sealing mailers

This pack contains fifty white poly mailers sized 12 by 15.5 inches. Each bag features a self-sealing adhesive strip that remains effective across all seasons without drying out. The matte finish provides a professional appearance and a writable surface for labels. They are intended for shipping non-fragile items such as clothing, documents, or soft goods.

Upgrade from tape-sealed or glossy bags

Switching to these mailers removes the need for separate packing tape and eliminates the risk of adhesive failure in hot or cold weather. The 1.6 inch extended sealing flap ensures the full interior dimensions are usable, unlike bags that count flap length in their sizing. The jump is worth it for high-volume shippers who want faster packing and a consistent, clean seal every time.

Fits into a fulfilment workflow

The flat, lightweight bags store compactly and dispense quickly from a shelf or bin. They require no additional cushioning material for soft products, freeing up space and reducing pack weight. The matte exterior accepts marker or label printer output without smudging. They are not suited for fragile items that need bubble padding or rigid protection.

Questions about this item

Will the 1.6 inch sealing flap reduce the usable length of the 15.5 inch mailer?

The flap extends 1.6 inches beyond the stated 15.5 inch length, so the full interior depth remains available for contents.

What surface preparation ensures the self-sealing adhesive bonds correctly on these matte-finish mailers?

Press the flap firmly onto the clean, dry bag body; the adhesive is designed not to dry out across seasonal temperature changes.

When should I replace a roll of these poly mailers if the adhesive loses tack?

The adhesive is formulated not to dry out during Spring, Summer, Fall, or Winter; replace only if the seal fails after firm pressure.
