Business, security and mailing envelopes - choose the right type

Choose envelopes for documents, confidential documents or products. We focus especially on options that help protect personal information.

Security envelopes with inside printing

Inside printing makes contents harder to read through the paper. Choose opacity, size and closure for HR, financial or medical documents.

Custom printed business envelopes

Your logo, return address and a design suited to your brand. Ask about everyday business envelopes and one-off print runs.

Document envelopes

Ask about DL, C6, C5 and C4 sizes, with or without windows. Size, paper and closure availability are confirmed in your quotation.

Padded envelopes

Cushioned options for small items. Choose protection according to weight, shape and transport conditions.

Coloured and metallic envelopes

For invitations, promotional materials and brand presentation. Colour, finish and printing options depend on the selected model.

Mailing bags and dispatch packaging

An alternative for shipping products. Ask about sizes, available materials and suitable closures.

Choosing envelopes for confidential documents

Check paper opacity, inside printing, closure strength and whether the window reveals only address details. If you need evidence of attempted opening, specify this in your enquiry - inside printing alone does not provide that function. Model specifications are confirmed in the quotation and through samples.

PROTECT THE CONTENTS

Choose opacity, inside printing and closure strength for the contents. Inside printing makes documents harder to read through the paper; it does not prevent opening.
