Product Information

Full details

The Q-Connect C4 Board Back Envelopes are ideal for administrative professionals and businesses that need to mail certificates, photographs, or legal documents that must remain pristine. Featuring a rigid backing to prevent folding and a secure peel-and-seal closure, these envelopes provide a professional solution for protective mailing; however, their rigid nature means they are strictly limited to flat items and cannot accommodate bulky objects.

FAQs

Can I fit A4 documents inside these envelopes?

Yes, the C4 size is specifically designed to accommodate A4 documents comfortably without the need to fold them.

Does the peel-and-seal require water?

No, the peel-and-seal closure is pressure-sensitive and requires no water or moisture.

Are these envelopes opaque?

Yes, the 120gsm paper thickness offers good opacity, keeping your private documents obscured during transit.

How many envelopes are in one pack?

This pack contains 125 envelopes.

Can I print directly onto these envelopes?

Yes, most standard office printers can handle these envelopes, though you should verify your printer's manual for thickness settings.

What is the weight of the paper used?

These envelopes are constructed using high-quality 120gsm paper.

Troubleshooting

Adhesive strip not sticking

Ensure the surface area is free of paper dust and that you are applying firm, consistent pressure across the entire flap.

Envelope bent during transit

While the board back provides protection, consider adding a secondary stiffener inside if mailing items that are extremely susceptible to damage.

Pros and Cons

Pros

  • High-quality 120gsm paper resists tearing
  • Rigid backing effectively protects against folding
  • Peel-and-seal strip is fast and efficient
  • Professional white appearance
  • Clear 'Please do not bend' warning label

Cons

  • Not suitable for bulky or three-dimensional items
  • Single-use adhesive cannot be re-sealed if opened
  • Paper finish can be susceptible to heavy moisture damage
  • Rigid back makes it slightly heavier for postage calculations

Setup, Compatibility & Care

To ensure the best results, place your documents centered within the envelope to prevent edge bending. Peel the protective strip from the adhesive line, fold the flap over firmly, and press down for three to five seconds to activate the pressure-sensitive glue. Store these envelopes in a cool, dry place away from direct sunlight or excessive humidity, as these factors can cause the adhesive strip to prematurely lose its tackiness or the paper to warp. Ensure the mailing address is written clearly on the front using a permanent marker or a standard laser-printed label for optimal readability.
