Product Information

Full details

The Office C4 Gusset Envelopes are designed for administrative professionals and offices needing to mail bulky documents, reports, or thick brochures. These envelopes provide the benefit of a 25mm V-base gusset which allows for expanded capacity while maintaining a professional manilla finish. A notable caveat is that their heavier construction and size may require additional postage compared to standard flat envelopes when filled to maximum capacity.

FAQs

What is the maximum capacity of these envelopes?

The envelopes feature a 25mm gusset, allowing them to hold a stack of paper up to 25mm thick.

Do I need to moisten the adhesive?

No, these envelopes feature a convenient peel and seal closure; simply remove the protective strip to seal.

Can I fit standard A4 paper inside?

Yes, the C4 size (324mm x 229mm) is designed to fit A4 paper perfectly without folding.

Are these envelopes opaque?

Yes, the 115gsm manilla paper provides a high level of opacity, ensuring the contents are not easily visible from the outside.

How many envelopes come in a pack?

Each box contains 125 individual C4 gusset envelopes.

Troubleshooting

Envelope flap not adhering properly

Ensure the surface of the envelope is clean and free of paper dust, and apply firm, even pressure across the entire adhesive strip.

Difficulty inserting bulky documents

Ensure the V-base gusset is fully expanded before sliding the document bundle into the envelope to minimize friction.

Pros and Cons

Pros

  • Expands to accommodate thick document sets
  • Secure peel and seal mechanism saves time
  • Sturdy 115gsm paper weight offers enhanced protection
  • Large C4 size allows for flat mailing of A4 sheets

Cons

  • Heavier weight may increase postage costs
  • Limited to a professional manilla aesthetic
  • Requires more storage space than standard flat envelopes

Setup, Compatibility & Care

To ensure the best results, place your document stack squarely within the envelope to prevent uneven stress on the gusset. When sealing, remove the adhesive backing strip carefully and press firmly across the entire flap to ensure a complete bond. Store the box in a cool, dry place to prevent the adhesive from prematurely drying out or the paper from absorbing humidity, which could compromise the structural integrity of the envelope.
