E-type corrugated cardboard envelopes - strong and versatile
E-type corrugated cardboard envelopes are exceptionally durable, made of three-layer corrugated cardboard with an E-wave structure, with a thickness of 1.5-1.8 mm. This structure provides solid protection for the contents of the package, protecting it from pressure and shocks during transportation. These envelopes also have the unique feature of being height adjustable thanks to additional fold lines, making them perfect for a wide range of contents, from thin documents to thicker items such as books or magazines.
Corrugated envelopes are perfect for sending:
- Books and catalogs
- Documents and contracts
- Brochures and promotional materials
- Small electronic accessories
- Other flat and sensitive items
