An alternative to cardboard boxes


Ecommerce packaging bags with a block base ship bulkier, non-fragile goods in FSC-certified brown Kraft paper. The block bottom and side gussets of these brown paper postal bags open out so the bag expands around voluminous or irregular items, giving a lightweight alternative to a cardboard box. A wide self-adhesive flap with a paper release liner closes the bag with a tamper-evident seal. A fine serrated cut at the opening reduces the risk of catching a sharp edge in handling. The Kraft paper resists wear and light moisture, though it isn't waterproof. These ecommerce packaging bags hold 50% recycled content and are fully recyclable.

Sold and priced per pack, in a range of standard sizes.

Where do block bottom mailing bags work best?

Block bottom ecommerce packaging bags suit businesses that want a recyclable paper alternative to a box for bulkier, non-fragile goods.

  • Clothing and textiles, where the block bottom and side gussets expand around folded garments and soft accessories.
  • Irregular or voluminous items, where the expandable base holds products that won't sit flat in an envelope.
  • Outbound parcels and returns, where the wide self-adhesive flap gives a quick tamper-evident seal at the bench.
  • Plastic-reduction policies, where FSC Kraft with 50% recycled content supports paper-based despatch.

FAQs

How do the block bottom and side gussets help?

They let the bag expand for bulkier or irregular items, so it works where a flat envelope or mailer won't.

Are these paper mailing bags for bulky items waterproof?

No. Kraft paper resists light moisture but isn't waterproof; use a liner or a plastic alternative for water-sensitive goods.

Are they suitable for fragile items?

No. These brown postal bags are not padded. For fragile goods, add cushioning such as bubble or use a padded alternative.

Can customers recycle them?

Yes. The bags are fully recyclable and made with 50% recycled content.

Do they show tampering?

The wide self-adhesive flap forms a tamper-evident seal, so opening marks the closure area.

Also useful

  • Labels for address and carrier details on the Kraft paper surface.
