Pack of 100 White Poly Bubble Mailers

This pack contains one hundred new padded envelopes sized at 8.5 by 12 inches. The pure white poly exterior is self-sealing for quick closure and tamper evidence. They are intended for anyone shipping small items who wants a lightweight protective layer. Buyers needing larger formats or a different quantity will need another option.

Practical Limits of the Self-Seal Closure

The peel-and-seal strip creates a permanent bond that cannot be reopened without visible damage. Once pressed shut the envelope is tamper-evident and not reusable. The adhesive is designed for single-pass shipping and is not rated for repeated opening or long-term archival storage. Users who require resealable packaging should look elsewhere.

Internal Bubble Dimensions Decide Fit

The internal cushion space is defined by the 8.5 by 12 inch outer size and the 0.2 inch overall thickness. Only objects that fit within that flat profile and can tolerate minimal corner clearance will be protected by the finned bubble layer. Items thicker than the envelope depth or requiring rigid corners are not suited to this mailer.

Questions about this item

Should I pick the 100-pack of 8.5" x 12" mailers or a smaller quantity for occasional shipping?

The 100-pack suits high-volume shippers; each bag measures 8.5 by 12 inches and weighs very little, so storage space stays minimal.

How much protection does the finned bubble lining give when the envelope is inside a parcel?

The heavy-duty bubble layer is finned on three sides, absorbing impacts and keeping contents secure during transit.

Does the self-seal closure meet tamper-evident requirements for courier pickup?

Yes, the peel-and-seal strip creates a permanent bond that cannot be reopened without visible damage.
