FAQs

Can I use these for international shipping?

Yes, they are suitable for international shipping, provided the items are correctly labeled and weigh within the limits set by your carrier.

Are these envelopes waterproof?

No, they are made from a paper outer layer, which provides basic moisture resistance but will not protect contents during heavy rain or immersion.

How do I recycle these bags?

They contain 60% recycled materials. Please check your local municipal guidelines as you may need to separate the plastic bubble liner from the paper outer layer.

What is the primary use for the J/6 size?

The J/6 size (300 x 440mm) is ideal for large documents, catalogs, clothing, or small electronics that require protection during transit.

Does the weight of the bag impact postage costs?

Yes, because the bag uses a lightweight 70gsm paper, it helps keep your package weight lower, which can keep you within lower postage weight tiers.

Troubleshooting

Adhesive strip is not sticking securely

Ensure the surface is free from paper dust or debris, and apply firm, even pressure along the entire length of the flap for several seconds.

Envelope feels too thin for sharp or heavy items

Wrap sharp-edged items in an additional layer of bubble wrap or cardboard before inserting into the mailer to prevent punctures.

Pros and Cons

Pros

  • Significantly reduces shipping weight compared to cardboard boxes
  • Excellent internal protection with AirCap bubble technology
  • Simple, fast packing with the self-seal adhesive closure
  • Easy for recipients to open via the integrated tear strip
  • Contains 60% recycled content for better sustainability

Cons

  • Paper exterior is not waterproof for long-term outdoor exposure
  • Limited to smaller or flatter items due to envelope thickness
  • White exterior is susceptible to dirt or ink smudges during transit

Setup, Compatibility & Care

To ensure the best performance, place your items flat inside the envelope and ensure they do not exceed the 300 x 440mm dimensions, as overstuffing may weaken the structural integrity of the sides. Simply peel back the protective liner on the adhesive strip, fold the flap over firmly, and press down across the entire width for a complete seal. Store these bags in a cool, dry place away from direct sunlight or heavy moisture to prevent the paper from yellowing or the adhesive from degrading over time. While the bags are recyclable, it is recommended to check local facility guidelines regarding the separation of the bubble lining from the paper exterior.
