Machine envelopes are specifically manufactured to work smoothly with automated equipment, ensuring consistent feeding, accurate sealing and reliable performance during large mail runs.

Envelopes for mailing machines and automated systems

Machine envelopes, also known as machinable or insertable envelopes, are designed to be compatible with mailing and inserting machines. Their precise dimensions and construction allow them to move efficiently through automated systems, reducing the risk of jams or misfeeds. :contentReference[oaicite:0]{index=0}

They are commonly used in offices, mailrooms and businesses that send large volumes of letters, invoices and statements.

Designed for smooth performance and efficiency

Unlike standard envelopes, machine envelopes feature specific design elements such as tailored flap shapes, consistent sizing and suitable sealing methods to ensure reliable machine processing. :contentReference[oaicite:1]{index=1}

Using the correct envelopes for your mailing equipment helps improve efficiency, reduce downtime and maintain consistent output quality across bulk mailings.

Available in multiple sizes and formats

Our range includes popular envelope sizes such as DL, C5 and C6, available in both window and non-window formats. Machine envelopes are often slightly larger than standard envelopes to support automated insertion processes. :contentReference[oaicite:2]{index=2}

Options are available in white and manilla finishes, as well as different paper weights to suit your business requirements.

Ideal for invoices, statements and business mail

Machine envelopes are widely used for sending invoices, statements, marketing materials and general correspondence. Their compatibility with mailing machines makes them ideal for organisations handling high volumes of outgoing mail.

For document creation and printing, you can also explore our plain paper or listing paper for continuous printing applications.

Compatible with franking machines and mailroom equipment

These envelopes are commonly used alongside franking machines and inserting systems from leading manufacturers. Choosing high-quality, compatible envelopes helps ensure smooth operation and prevents issues such as smudging, misalignment or machine jams. :contentReference[oaicite:3]{index=3}

For secure or specialist mailing needs, you may also find our high security envelopes or board backed envelopes useful.
