Thanks to their unique features and benefits, DuPont™ Tyvek® envelopes are practically indestructible ensuring your important documents and heavy bulky items arrive safely at their destination.

Tyvek® envelopes and sleeves can be used for almost any kind of mail.  Recommended for important mail, legal documents, contracts, catalogues, manuals, wage slips, personnel info, annual company reports… any time protection and confidentiality are needed.

These envelopes come with a side gusset that opens w-i-d-e to accommodate bulky items. An ideal replacement for boxes and reinforced paper envelopes, being tough and economical, they help save on postage too.  Ideal for sending books, binders, files, catalogues, clothing, spare parts and samples.

These envelopes offer an extra measure of confidentiality and security. Once the tamper-evident seal is 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.
Highly recommended for confidential, sensitive or valuable documents and mail: human resources files, medical reports, financial statements, evidence/case files, contracts, certificates, legal documents and more.
