C4 Ultra White Premium Office Peel & Seal Blue Hatch Window Pocket Gusset Envelopes (140gsm)

Elevate your professional and personal correspondence with C4 Ultra White Premium Office Peel & Seal Blue Hatch Window Pocket Gusset Envelopes (140gsm). Crafted for organisations and individuals who require maximum capacity, efficiency, and security without compromising on refinement, these large-format envelopes feature an expandable 25mm gusset to accommodate bulkier mailings with ease. Made from heavy-duty, high-quality 140gsm paper, they offer an exceptionally robust construction with superior opacity—ensuring both a luxurious tactile feel and ultimate protection for substantial contents inside.

The Ultra White shade provides a bright, pristine aesthetic that enhances the presentation of your mailings, while the precisely positioned 40mm x 105mm clear window (placed 213mm from the top and 24mm from the left edge) allows printed addresses to show through perfectly, streamlining your mail preparation process. For added confidentiality, the internal blue hatch pattern offers an extra layer of privacy by preventing sensitive details from being read through the paper. Designed as a pocket-style envelope with the opening on the shorter side, it allows for efficient top-loading of thick, multi-page document bundles. Whether you’re sending heavy business reports, legal files, bound contracts, or marketing kits, these envelopes project a polished and contemporary appearance. They are also fully compatible with both digital and inkjet printers, making them an excellent choice for businesses needing reliable print performance on high-capacity envelopes.

The convenient peel & seal closure ensures secure, hassle-free sealing, maintaining the confidentiality and integrity of your documents from dispatch to delivery. Perfectly sized to meet C4 specifications but enhanced with a 25mm expansion, these envelopes are ideal for thick, unfolded A4 documents, booklets, or catalogues, offering versatile functionality for heavy-duty corporate applications.
