Product Information

Full details

The Q-Connect Envelope (KF3450) is designed for busy professionals and office managers who require a reliable solution for sending or storing large, A3-sized documents. Built with heavy-duty 115gsm paper, these envelopes provide excellent protection for contents during transit or filing, though their large 406 x 305mm footprint may be excessive for smaller standard mailings.

FAQs

Are these envelopes suitable for international mailing?

Yes, provided the contents and weight adhere to your local postal service requirements for large envelopes.

Do I need to use water to seal these?

No, these are self-seal envelopes featuring a pre-applied adhesive strip.

How many envelopes come in a pack?

Each box contains 250 individual envelopes.

Can I print directly onto these envelopes?

While the 115gsm paper is heavy, most standard office printers can handle these envelopes, provided your printer has a manual feed tray for larger media.

Are these envelopes opaque?

Yes, the manilla material is thick enough to ensure the contents remain private during transit.

Troubleshooting

Adhesive strip not sticking

Ensure the adhesive area is free of dust or paper fibers. If the strip feels dry, apply light pressure for a few seconds to reactivate the bond.

Envelope flap curling

Store the pack flat in its original box to prevent the moisture or environmental factors from affecting the paper fibers.

Pros and Cons

Pros

  • Durable 115gsm paper construction
  • Time-saving self-seal adhesive mechanism
  • Generous sizing for large format documents
  • Bulk pack size reduces restocking frequency

Cons

  • Large size may require more storage space
  • Not suitable for small or standard letters
  • Manilla style is strictly functional rather than decorative

Setup, Compatibility & Care

These envelopes do not require complex setup; however, users should ensure that the contents are centered within the envelope to prevent bunching at the edges. Since these are designed for large documents, confirm that the items do not exceed the 406 x 305mm dimension to allow the flap to seal properly. For storage, keep the box in a cool, dry environment away from direct sunlight to maintain the integrity of the self-seal adhesive strip. Avoid stacking heavy objects directly on top of the box to prevent crushing or deformation of the envelopes.
