    The sustainable and secure alternative to paper, cardboard, or plastic envelopes. The security envelopes have a characteristic shape, last for years, and are ideal for sending confidential or valuable documents.

    The security envelopes protect the contents within and are also available with a seal.

    The envelopes are made with opaque plastic to enable you to send documents and files confidentially and discreetly. This also reduces the risk of theft, because the contents are not visible.

    The security envelopes come in three sizes:

    • Small: 350 mm x 250 mm (zipper on the short side)
    • Medium: 400 mm x 300 mm (zipper on the long side)
    • Large: 480 mm x 330 mm (zipper on the long side)

    The small model is ideal for the commonly-used A4 paper size. The small envelope has a bit of extra room so that it can also accommodate thicker stacks of A4-sized documents.
