Shipping mailers for small items

Partners Brand B803 self-seal padded mailers come in a pack of twenty-five white envelopes sized six by ten inches. They suit retailers and home sellers who ship jewellery, electronics accessories or other compact goods. The self-sealing flap removes the need for tape or a separate moisture sponge. This quantity covers regular despatch runs without excess stock.

Lightweight protection in transit

Each mailer uses integrated padding to cushion contents against everyday knocks and compression in the post network. The paper-based construction keeps the parcel light so postage costs stay predictable. No external power or special handling is required during packing. The sealed closure stays secure through automated sorting equipment.

Ready-to-use pack of twenty-five

The box delivers twenty-five mailers in a single pack so the workstation stays stocked for multiple orders. No additional inserts, labels or software are bundled with the product. Users simply fold the flap, press to seal and apply the shipping label. The plain white surface accepts handwritten or printed addresses cleanly.

Questions about this item

How do I seal the self-adhesive flap on these 6 x 10 mailers without trapping air?

Press the flap down from the centre outward so the padded layers stay flat; trapped air creates bubbles that weaken the bond.

When should I replace a mailer that has been stored in the box of 25?

Replace any mailer whose adhesive strip feels tacky or whose padding feels compressed, as both reduce cushioning and seal strength.

What is the first limit I hit when packing heavy items into the 6 x 10 size?

The padded walls and self-seal flap will bulge or split before the 25-count pack is exhausted, signalling the mailer’s capacity limit.
