Material and Build

Manufactured from 80g envelope cartridge paper, this confidential envelope utilises a standard paper weight that balances durability with flexibility. The 80g specification indicates a medium-weight paper stock that provides sufficient rigidity to protect documents during postal handling while remaining flexible enough for easy document insertion and folding. This material choice represents a practical approach to envelope construction, offering adequate protection for typical confidential correspondence without the bulk or expense of heavier specialty papers. The paper's properties support the self-adhesive sealing system while maintaining the envelope's structural integrity throughout the mailing process.

With dimensions of 105mm by 240mm, this envelope provides a standard size suitable for various document security needs. The proportions accommodate A4 documents folded twice, creating a compact yet protective enclosure for letters, statements, or reports. The size also fits smaller documents without requiring folding, preserving their original format while maintaining security. This dimensional specification ensures compatibility with typical mailing requirements while providing sufficient space for address labelling and postal markings. The envelope's rectangular shape optimises material usage while providing a familiar format that integrates easily with existing mailing processes and storage systems.

Financial institutions might employ it for statements, tax documents, or confidential reports that require protection during postal transit. Healthcare providers could utilise it for patient communications where privacy regulations apply. The envelope's tamper-evident design offers visible assurance to both sender and recipient that documents have remained secure, potentially reducing concerns about information breaches during the mailing process.
