Self seal envelopes for invoices

Self-sealing envelopes provide fast closing without needing moisture and are ideal for sensitive documents. In this selection, you can find Gazelle options in DL and C4 formats with tinted interiors to help protect confidentiality—for example: DL Paper Envelope – 1 pack of 50 in white, Gazelle DL Paper Envelope DL 80 Gsm – Pack of 50, and Gazelle Paper Envelope C4 – Pack of 50 (100 Gsm). For large quantities, there are also bigger bundles such as packs of 150 or 200 pieces.

For standard invoices and professional documents, the DL format is ideal because it fits well with folded documents. For larger sets, the C4 format allows sending sheets without folding. Some A4 self-seal options offer 100 pieces and make it easier to organize and archive items at the office or at home.

To protect the contents, choose envelopes with tinted interiors, such as Gazelle DL models, which partially mask what’s inside once sealed. Make sure the seal is reliable and choose a format that matches your document size to avoid unnecessary folds.

Depending on usage, bundles range from 50 to 500 pieces. You can choose DL packs of 50 or 150 depending on your typical volume, C4 packs of 50 for larger documents, or A4 self-seal options that offer 100 pieces for everyday use.

Self-sealing envelopes close without moisture, which speeds up mailing and helps avoid mistakes when sealing. Non-self-sealing envelopes require moistening or adhesive to seal the documents, which can slow down workflow.

Yes. The selection covers both business and personal use: office formats (DL, C4) and A4 envelopes for personal archiving, available in multiple pack sizes to match your mailing pace.
