Product Information

Full details

These 5 Star Office DL envelopes are designed for administrative professionals and businesses requiring a reliable solution for daily correspondence and transactional mail. The key benefit is the combination of a convenient peel and seal closure with a security-focused opaque interior that protects sensitive documents during transit. One caveat to keep in mind is that while the 100gsm paper is high quality for standard use, it is a medium-weight stock that may not be suitable for heavy-duty protective shipping requirements.

FAQs

What is the weight of the paper?

These envelopes are made from high-quality 100gsm paper.

Can these envelopes go through an automated mailing machine?

Yes, the 100gsm paper is robust enough for most standard automated mailing and sorting equipment.

What is the size of the window?

The window measures 39x93mm.

How many envelopes are in one box?

Each box contains 500 envelopes.

Is the interior printed to be secure?

Yes, it includes a blue opaque interior to hide sensitive content from being read through the paper.

Do I need to lick these envelopes?

No, they feature a peel and seal closure, so no moisture is required.

Troubleshooting

Adhesive strip is not sticking properly

Ensure the envelope flap is clean and free of dust, and apply firm, even pressure across the seal for 2-3 seconds.

Address is not visible in the window

Check your printer settings to ensure your document layout corresponds to a standard DL window alignment (39x93mm).

Pros and Cons

Pros

  • Efficient peel and seal mechanism saves time
  • Opaque interior provides excellent document privacy
  • Standard DL dimensions fit common office document folds
  • High-quality 100gsm paper weight
  • Large 500-pack box is ideal for high-volume use

Cons

  • Not intended for shipping bulky items
  • Single-use adhesive strip means the envelope cannot be resealed once opened
  • Window size is fixed and may not fit all custom document print layouts

Setup, Compatibility & Care

To maximize the utility of these envelopes, ensure that your document templates are aligned correctly with the 39x93mm window position. Most standard word processing software, such as Microsoft Word or custom billing platforms, allow you to adjust 'window position' settings to match these dimensions.

Store the envelopes in a cool, dry place to prevent the adhesive strip on the peel and seal closure from prematurely curing or losing tackiness. Because the adhesive is pressure-sensitive, ensure the envelope flap is pressed firmly across the entire width of the seal to create a tamper-evident bond.
