Tyvek® is the DuPont™ brand name for spun-bonded olefin. Tyvek® sheets combine the best properties of paper, film and fabric. This unique combination of properties makes Tyvek® perfect for the envelope and packaging industry.

Tyvek® has established a new category in the industry:
The High Performance Envelope.

Tamper Evident Envelopes, Card Pouches & CD Sleeves
The performance of these products has been taken to a new level through the use of Tyvek® material instead of paper.

There are numerous advantages to Tyvek® envelopes and specialty products:

  • Tear-Burst-and Puncture-resistant.  They are incredibly strong  and practically indestructible giving unmatched protection.

  • Water-and moisture-resistant. An added dimension of protection and perfect for archiving and storage.

  • Flexible and lightweight  with an outstanding strength-to-weight ratio. Typically 2 to 3 times lighter than paper envelopes and boxes, yet considerably stronger making shipments lighter and significantly reducing mailing and shipping costs.

  • Distinctive looks. Bright white look and silky smooth feel which enhances graphic images and corporate logos.

  • Anti-static, non-abrasive and non-linting making it an excellent material for specialised applications aimed at optical and magnetized media.

  • 100% Recyclable. Tyvek® is made from 100% High Density Polyethylene (HDPE) Fibres, an environmentally responsible material, which can be recycled into other useful materials.

*DuPont™ makes the Tyvek® brand protective material; Tyvek® envelopes themselves are manufactured by independent firms that convert this unique, high-performance material into a vast array of styles and sizes.



Tyvek® envelopes and speciality products give high performance protection,image and feel and thanks to their durability and strength, cost savings in the long run.

Tyvek® High Performance Envelopes
Tyvek® envelopes are practically indestructible. They offer unsurpassed protection for all your important, confidential, heavy or bulky documents and ensure they arrive safely and in perfect condition.

They are available in a number of styles and sizes, usually with peel ‘n’ seal strips, with or without window patches and if needed complying to automatic insertions application requirements.

Tyvek® Tamper Evident Security Envelopes

Tamper Evident envelopes offer the ultimate level of security and confidentiality featuring a special security peel ‘n’ seal strip. Once a sealed envelope is opened and the tamper-evident seal broken, the word ‘OPENED’ appears in the flap window, letting the receiver know that the envelope has been opened and confidentiality lost. The tamper evident seal is a deterrent to ensure mail confidentiality. They are available in various designs and sizes, all featuring peel ‘n’ seal security strips.

ATM, Credit Card & Smart Card Pouches
Tyvek® card pouches act like long-lasting wallet billboards. They protect magneticstriped cards from the damage and scratches of daily use. They offer a high-impact, low-cost promotional vehicle and are available with customised graphics in a variety of styles and sizes.

CD and DVD Sleeves
Nothing protects discs like Tyvek® sleeves. Unlike paper and SBS board, Tyvek® disc sleeves resist tears, water and chemicals. In fact, independent performance tests designed to simulate extreme shipping, use and storage conditions proved that Tyvek® sleeves protected ROM and recordable discs better than alternative packaging systems – and were equally protective as costly jewel boxes.
They are available with customised graphics in a variety of styles and sizes.
