Product Information

Full details

Designed for professionals and home office users who need to mail fragile or flat documents, these iSOUL manilla envelopes provide superior protection through a rigid, hard board backing. They offer the convenience of a peel-and-seal closure and clear 'Do Not Bend' warnings, making them perfect for shipping certificates, photographs, and important letters. Please note that while the hard board offers excellent protection, it adds to the overall weight of the package, which may impact postage costs compared to standard paper envelopes.

FAQs

Can I use these envelopes for mailing standard letters?

Yes, but they are specifically designed for documents that require protection from bending. For standard, non-sensitive letters, they may be heavier than necessary.

Do I need to moisten the adhesive?

No, these envelopes feature a peel-and-seal strip that requires no moisture.

What sizes are included in the pack?

The pack contains a mix of A4 and A5 sizes.

Are the envelopes opaque?

Yes, the manilla material is thick and opaque, ensuring privacy for your documents.

Will the 'Do Not Bend' sign guarantee my mail won't be folded?

It acts as a warning to postal handlers, but professional care depends on the specific mail courier's service standards.

Troubleshooting

The adhesive flap is not sticking properly.

Ensure the surface is free of dust or paper fibers. Apply firm, consistent pressure across the entire seal for several seconds.

Contents are sliding around inside the envelope.

Use a small piece of removable tape to fix the document to the internal board, or include a thin piece of paper to fill the gap if the document is significantly smaller than the envelope size.

Pros and Cons

Pros

  • Rigid backing protects contents from bending
  • Easy-to-use peel and seal adhesive
  • Includes both A4 and A5 sizes for versatility
  • Professional appearance with clear handling instructions

Cons

  • Increased weight may result in higher postage costs
  • Not intended for non-flat or bulky items
  • Hard board is not flexible for overstuffing

Setup, Compatibility & Care

To ensure the best performance, place your documents centrally within the envelope to allow the protective board to cover the entire surface area. Ensure that the document does not exceed the thickness capacity of the envelope; these are intended for flat items. When sealing, peel the release strip firmly and apply even pressure across the flap to guarantee a secure, permanent bond. Store these envelopes in a cool, dry place away from direct sunlight to maintain the integrity of the adhesive strip. Avoid overstuffing the envelopes, as excessive thickness can compromise the closure seal and potentially damage the rigid backboard.
