Product Information

Full details

The 5 Star Office Pocket Envelopes are designed for busy office managers and administrative professionals who require a reliable, efficient solution for high-volume mailing. These C5 envelopes offer the convenience of a press-seal closure, significantly speeding up document preparation compared to traditional gummed flaps. While their 90gsm manilla construction provides standard durability for general correspondence, they are best suited for internal office use or standard business mailings rather than heavy-duty shipping or high-security document transit.

FAQs

What does C5 size mean?

C5 size (229x162mm) is specifically designed to hold an A4 sheet of paper folded in half.

Does this envelope require moisture to seal?

No, this is a press-seal envelope, which uses a self-adhesive strip that bonds upon contact.

Are these envelopes suitable for international airmail?

They are suitable for standard mail, though they do not offer extra padding or moisture-proof protection for international transit.

What is the weight of the paper used?

These envelopes are made from 90gsm manilla paper, which is a standard, durable weight for business correspondence.

Can I use these in an inkjet printer?

Yes, they are generally compatible with most standard office printers, but always test one envelope first to check for ink smearing or jamming.

Troubleshooting

Envelope seal is not sticking properly.

Ensure the adhesive strip is free of paper dust and that the flap is firmly pressed for at least two seconds.

Printing jams occur when feeding through the printer.

Use the manual feed tray on your printer and ensure the envelopes are loaded in the correct orientation according to your printer's manual.

Contents are visible through the manilla paper.

The 90gsm manilla is semi-opaque; for highly confidential documents, consider folding the paper so that text is not positioned directly against the outer envelope walls.

Pros and Cons

Pros

  • Efficient press-seal closure saves significant time
  • Bulk pack of 500 is cost-effective for large offices
  • Standard C5 size accommodates most common document folds
  • Durable 90gsm paper prevents easy tearing in the post

Cons

  • Not suitable for heavy-duty protection of delicate items
  • Manilla finish is utilitarian and less formal than white wove
  • Self-adhesive strip may lose effectiveness if stored in extreme humidity

Setup, Compatibility & Care

These envelopes do not require complex setup; they are ready for use immediately upon opening the pack. For optimal results, ensure your printer or copier settings are adjusted if you intend to print addresses directly onto the envelopes, as the thickness of the 90gsm manilla paper may differ from standard printer paper.

Store the box in a cool, dry place. Excessive moisture or extreme heat can negatively impact the integrity of the press-seal adhesive, potentially causing the envelopes to seal prematurely or lose their stickiness over long periods. Keep the box closed when not in use to protect the remaining envelopes from dust and humidity.
