Self-Seal Bubble Mailers #4

These Partners Brand mailers provide cushioned protection for items shipped in bulk. The self-sealing closure removes the need for separate tape during packing. A pack contains 70 units, suited for small businesses or high-volume shippers. The kraft exterior resists tearing during transit.

Behaviour under sustained shipping load

Each mailer maintains its bubble cushioning through repeated handling cycles in carrier networks. The adhesive strip stays bonded across temperature shifts encountered in sorting facilities. Kraft material resists punctures when packages are stacked under heavier parcels. The 70-count pack supports continuous fulfilment without frequent reordering.

Practical limits of the mailer format

Internal dimensions restrict contents to items that fit within the 9 1/2 by 14 1/2 inch envelope. Rigid or heavy objects may exceed the bubble padding's protective capacity. The self-seal flap is designed for single use and cannot be resealed after opening. Buyers needing larger volumes per shipment or reusable closures should consider alternative packaging.

Questions about this item

Will the self-seal adhesive hold up if the mailers sit in a warm warehouse all day?

The self-seal closure is designed to stay secure during normal shipping conditions; store the pack flat in a cool, dry area to maintain adhesive performance.

Do I need any extra tape or a sealing machine to close these mailers?

No additional tape or equipment is required — each mailer has a built-in self-seal strip that you press to close.

Can I use these #4 mailers alongside the smaller #0 and #2 sizes I already stock?

Yes, the #4 format (9 1/2" x 14 1/2") fits the same packing workflow as other sizes; just choose the size that matches each shipment.
