Lockwise Courier Envelopes are mailing envelopes with permanent adhesive made from high-opacity materials. Full confidentiality of the contents is guaranteed by the opaque finish, which prevents the inside from being seen from any angle.
They are resistant to bursts, tears and punctures, and are fully protected against weather conditions (weather proof). The outer surface is suitable for writing with a pen or permanent marker, making manual identification easier in the field.
The material is 100% recyclable. They are available in all sizes and shapes according to requirements. Full customization is available: logos, exclusive designs, unique sequential numbering and barcode integration for automated control in logistics centers.
