Product Information

Full details

The Plus Fabric C4 Gusseted Pocket Envelopes are designed for professionals and businesses that require a secure, durable solution for mailing bulky documents, including thick reports, brochures, and catalogs. Crafted from heavyweight 120gsm bright white paper, these envelopes provide a professional presentation and superior protection during transit; however, their larger gusseted profile means they may require extra postage compared to standard flat envelopes.

FAQs

What does C4 size mean?

C4 size is specifically designed to hold an A4 sheet of paper without needing to fold it.

Can I run these through a printer?

While these are designed for manual insertion, standard laser printers may struggle with the thickness and gusset; check your printer's manual for heavy media handling.

Is the envelope opaque enough for sensitive documents?

Yes, the blue opaque interior is specifically designed to obscure the contents and ensure confidentiality.

What is the weight of the paper used?

These envelopes are made from 120gsm paper, which is significantly thicker and more durable than standard 80gsm or 90gsm office envelopes.

How do I store these effectively?

Keep them in their original packaging in a climate-controlled environment to prevent the adhesive from drying out or the paper from absorbing humidity.

Troubleshooting

Adhesive strip is not sticking properly.

Ensure the envelope flap is clean and dry. Apply firm, consistent pressure for 5-10 seconds to fully engage the Power-Tac adhesive.

Paper appears wrinkled after insertion.

Ensure your document stack is neatly squared before insertion. If the stack is near 25mm thick, insert it slowly to avoid catching on the gusset edges.

Pros and Cons

Pros

  • Durable 120gsm paper weight
  • Expanding gusset handles bulky items effectively
  • Secure Power-Tac peel-and-seal closure
  • Opaque interior for data privacy

Cons

  • Increased bulk may affect postal rates
  • Not suitable for small or thin single-page correspondence
  • Strictly for C4/A4 sized materials

Setup, Compatibility & Care

To ensure the best results, insert your documents carefully to prevent corner snags on the gusset. When sealing, apply firm, even pressure across the entire length of the flap to activate the Power-Tac adhesive. Store these envelopes in a cool, dry place to ensure the adhesive strip maintains its shelf life and bond strength. These envelopes are compatible with standard postal regulations for C4 sized packaging; always verify the thickness with your local post office if the final package exceeds 25mm in total depth.
