Description

Protect your sensitive paperwork with Triplast's 500-piece DL security envelope pack. Each white, fully opaque envelope measures 110 mm x 220 mm and is printed on 90 gsm paper that resists bleed-through, keeping contents hidden from prying eyes. Inside, a blue high-security pattern scrambles any text, ensuring confidential documents stay concealed during transit or storage. The self-seal adhesive eliminates the need for tape, glue or licking-just fold the top flap and press to lock the envelope shut. This hassle-free sealing saves time and reduces mess, making it ideal for busy offices, home businesses, and commercial mailing operations. The envelopes are printer-safe, so you can print addresses, barcodes, or labels directly onto the surface without smudging. Made in the UK, these envelopes combine reliable security with everyday practicality. Whether you're sending contracts, invoices, or personal letters, Triplast's security envelopes give you confidence that your information arrives safely and privately.

Key Features

High-security blue pattern inside scrambles text, keeping confidential information invisible while the envelope is in transit or storage.

Self-seal flap requires no tape, glue, or licking-simply fold and press to secure, saving time and eliminating mess in busy mailing environments.

Fully opaque 90 gsm white paper prevents light penetration and bleed-through, ensuring the contents remain hidden from view.

Printer-safe surface allows you to print addresses, barcodes, or labels directly onto the envelope without smudging or damage.

Made in the UK, providing consistent quality and reliable performance for home, office, and commercial mailing needs.
