Padded Self-Adhesive Bubble Mailers Office Products HK F16 220×340mm/240×350mm 10 pcs white

Padded self-adhesive bubble mailers Office Products HK F16 are lightweight protective envelopes sized 220×340 mm (outer dimensions 240×350 mm). This pack of 10 white mailers features an internal bubble-foil lining that cushions small items, documents and fragile goods during postal and courier transit. The mailers close with a self-seal adhesive strip for fast, secure packing without additional tape or glue.

Advantages

These bubble mailers combine a thin, flexible outer layer with internal air-cell padding to absorb shocks and reduce surface damage. The self-adhesive closure provides quick, tamper-resistant sealing while keeping handling simple. Their lightweight construction minimises additional postage costs compared with rigid boxes and the white exterior offers a clean, neutral appearance suitable for business correspondence and retail shipments.

How to use

Insert the item into the mailer so it rests against the padded interior, ensuring fragile elements are positioned away from the open edge. Remove the protective strip from the adhesive tape, fold the flap over and press firmly along the seal to secure closure. For irregularly shaped or extra-fragile goods, add additional internal protection or place the item centrally to maximise cushioning.

Usage recommendations

Verify dimensions of your items before packing to ensure a snug fit; do not overfill the mailer beyond recommended dimensions. For high-value or extremely fragile items consider supplementary protection such as foam wrap or a small rigid box inside the mailer and choose tracked shipping options when appropriate.
