Characteristics
Spunbonded from filaments of 100% high-density polyethylene (HDPE /olefin) by DuPont. It is chemically stable, mold and mildew resistant, lint-free, acid-free, and has a smooth surface. Resistant to wetting (billed as "waterproof"), but it allows transmission of moisture and vapor. Relatively inexpensive. "Type 10" styles are stiffer than garment-weight "soft" (Type 14) or perforated (Type 16) styles.
Forms/Sizes
Rolls 36” to 60” wide and up to 100 yds long. Thicknesses: 1025 type is 6.6 mils, 1020 type is 7.3 to 7.6 mils. Various sizes of pre-made folders, media sleeves, envelopes and expansion envelopes.

Applications
A high-strength barrier and wrapping material. Also used as a handling support for textiles, and to make non-abrasive, tear-resistant envelopes and media sleeves. Because it is vapor-permeable, use as a barrier to block off-gassing from plywood and/or glue, especially in storage situations, may not be the best choice.
