Envelopes with a Long-Side Opening

Why do so many people love envelopes with a long-side opening? The wide opening makes inserting and removing contents quick and intuitive, without the risk of creasing or damaging the paper. This is especially important when sending letters, invoices, informational materials, or documents that require a flawless presentation.

These types of envelopes are ideal for mass mailings, administrative correspondence, and corporate use. Of course, our range doesn’t include just one version of this product. What can you find at Boxmarket? Among others:

Window Envelopes – A practical solution that allows you to display address details without additional labeling. The window streamlines the mailing process and minimizes the risk of errors, making these envelopes a common choice in offices, accounting departments, and companies handling bulk correspondence.
Security Printed Envelopes – Designed with confidentiality in mind. Internal printing limits visibility of the contents, keeping documents discreet and protected from accidental reading. This solution is ideal for sending invoices, contracts, and letters containing sensitive information.
Classic Paper Envelopes – Universal and timeless. Perfect for everyday correspondence and for sending documents that don’t require extra security but still need to look professional and neat. A simple form that simply gets the job done.
