Its self-adhesive packaging design provides a tamper-evident seal, making any attempt to open the envelope visibly apparent. Measuring 105mm by 240mm and made from 80g cartridge paper, it is suited for mailing folded A4 documents, confidential reports, or personal letters that require integrity during transit. The single-unit packaging means it is intended for one-time use, providing peace of mind for sensitive mail without complex security systems.\u003c\/p\u003e\n\u003ch2\u003eFeatures and Construction\u003c\/h2\u003e\u003cdiv style=\"text-align: center;\"\u003e\u003cimg alt=\"Blue tamper-evident confidential envelope with self-adhesive flap, size 105mm by 240mm.\" src=\"https:\/\/images.seoo.uk\/src\/products\/shopify_export\/US14\/624\/2025-09-28\/original-image\/2401130309370321400.webp\"\u003e\u003c\/div\u003e\n\u003cp\u003eThe envelope’s primary function is to deter and reveal tampering through its simple, effective design. Its construction and size are tailored for standard postal handling while providing a clear visual indication if the contents have been compromised after sealing.\u003c\/p\u003e\n\u003ch3\u003eMaterial and Build\u003c\/h3\u003e\n\u003cp\u003eMade from 80g envelope cartridge paper, this material offers a balance between durability for postal transit and a lightweight profile to avoid excessive postage costs. The paper provides enough rigidity to protect enclosed documents from casual damage. The security feature is integrated into the flap design, which uses a self-adhesive strip. Once the protective liner is removed and the flap pressed down, it creates a seal that cannot be opened without leaving clear evidence, such as tearing or distortion of the paper.\u003c\/p\u003e\n\u003ch3\u003eSize and Practical Fit\u003c\/h3\u003e\n\u003cp\u003eThe envelope dimensions are 105mm in width and 240mm in height. This compact size is designed to accommodate standard A4 documents folded once into thirds, a common practice for business letters or formal correspondence. It fits neatly into standard postal sorting systems and letterboxes, making it a practical choice for both business and personal secure mailings where larger, padded options are unnecessary.\u003c\/p\u003e\n\u003ch2\u003eUses and Placement\u003c\/h2\u003e\u003cdiv style=\"text-align: center;\"\u003e\u003cimg alt=\"Blue tamper-evident confidential envelope with self-adhesive flap, size 105mm by 240mm.\" src=\"https:\/\/images.seoo.uk\/src\/products\/shopify_export\/US14\/624\/2025-09-28\/original-image\/2401130309370328500.webp\"\u003e\u003c\/div\u003e\n\u003cp\u003eThis product addresses specific scenarios where document confidentiality is important but high-cost security solutions are not required.
