Product Information

Full details

The White Box Self Seal DL Envelope 1000 Pack is an essential office supply for professionals and home users who require a high-volume, reliable solution for mailing standard A4-folded correspondence. These envelopes provide the significant benefit of a convenient self-seal closure that eliminates the need for moisture or extra adhesive, though users should note that the 90gsm paper is standard weight and best suited for letters rather than heavily textured or bulky document packets.

FAQs

What are the dimensions of these envelopes?

Do I need to lick these to seal them?

No, these are self-seal envelopes featuring a pressure-sensitive adhesive strip.

How many envelopes are in the box?

This pack contains 1000 envelopes.

Can these be used for postage in an automated mailing machine?

Yes, their standard DL dimensions are compatible with most office mailing equipment.

What is the weight of the paper?

The envelopes are constructed from durable 90gsm paper.

Are these envelopes opaque?

They feature standard 90gsm thickness, which provides good privacy for most standard documents.

Troubleshooting

Envelope flap not sticking correctly

Ensure the envelope is placed on a flat, hard surface and apply firm, even pressure along the entire length of the seal strip.

Printer jams when printing on envelopes

Check your printer settings to ensure the media type is set to 'Envelope' and verify the paper path is set to the correct orientation.

Adhesive strip feels dried out

Store envelopes in a sealed container or drawer; if the strip has been exposed to extreme heat or age, use a small amount of extra adhesive if necessary.

Pros and Cons

Pros

  • Secure self-seal mechanism saves time and effort
  • Large 1000-pack quantity is ideal for offices and bulk mailers
  • Standard DL size fits most business documents perfectly
  • Clean, professional white aesthetic

Cons

  • Not suitable for thick booklets or bulky items due to standard depth
  • Requires careful alignment of the flap for best adhesion
  • 90gsm paper is standard weight and may show through if using dark, bold print

Setup, Compatibility & Care

To ensure proper performance, store these envelopes in a cool, dry place away from direct sunlight and humidity. Prolonged exposure to moisture or excessive heat can degrade the adhesive strip. When sealing, apply firm, even pressure across the length of the flap to ensure the adhesive bond is complete. If printing, ensure your printer settings are adjusted for 'envelope' or 'heavy paper' to prevent jams.
