Specialty Envelopes: Questions & Answers about Tyvek^{^®}

^{^{What is TYVEK ?}}

Tyvek is high-density polyethylene (HDPE), the same ingredient used in food packaging, such as milk or water jugs. It's nontoxic, chemically inert, naturally white and contains no binders or fillers.

^{^{Why is TYVEK unique?}}

Tyvek is unique as the only specialty envelope to give you all this: durability and reliability due to its strength, water and chemical resistance, postage savings because it's lighter than paper, every size and style available for your convenience, 25% post-consumer recycled content, environmental responsibility and a great printed appearance.

^{^{What are the sales benefits of TYVEK ?}}

If you are going to sell specialty envelopes, think Dupont TYVEK^®. Tyvek is the only specialty envelope that is half as heavy as paper, four (4) times as strong, sends a message before they're even opened, can be automatically inserted, compatible with barcoding systems, and address labels have excellent adhesion to Tyvek. In many cases the postage savings pays for the improved image and performance from paper too!
