[DuPont] A registered trademark for a spunbonded olefin fabric. Tyvek is 100% [[high density polyethylene|high density polyethylene]] with no fillers or binders. It has fine, white, continuous filaments that are bonded by heat and pressure. Tyvek is chemically stable, lightweight, durable, strong, lint-free, and acid-free. The fabric is resistant to wetting, but it allows transmission of moisture and vapors. It is widely used as a wear resistant, tear resistant, waterproof paper for banners, maps, and envelopes. Applications also include filtration, packaging, bookcovers, interleaving, clean room clothing, protective garments, and carpet backing. Tyvek is commonly seen as a protective barrier in new housing construction. In museums, the high-strength wrapping material is used a soft, lint-free, waterproof liner in packing crates and display cases.  It is available in stiff (Type 10), soft (Type 14) and perforated (Type 16) forms.

[DuPont] Initially developed in 1955, this spunbonded, olefin product was trademarked in 1967. Tyvek® is 100% High density polyethylene without any fillers or binders. The fine, white, continuous filaments (0.5-10 microns) are bonded by heat and pressure to form a dimensionally stable, opaque sheet. Tyvek® is chemically stable, lightweight, durable, strong, lint-free, and acid-free. The paper/fabric is resistant to wetting, but it allows transmission of moisture and vapors. It is widely used as a wear resistant, tear resistant, waterproof paper for banners, maps, and envelopes. Applications also include filtration, packaging, bookcovers, interleaving, clean room clothing, protective garments, and carpet backing. Tyvek® is commonly seen as a protective barrier in new housing construction. In museums, the high-strength wrapping material is used a soft, lint-free, waterproof liner in packing crates and display cases. It is available in stiff (Type 10), soft (Type 14) and perforated (Type 16) forms (PACCIN). Tyvek® envelopes are used to store archival documents, photographic negatives or other small items. Tyvek® 6060 or 1073 has been recommended for paper-like labels; however, a sample should be tested before use to ensure that the ink does not soak through and transfer to the object below (Tetreault 2017).
