{{see also|Chemistry of adhesive tapes#Composition}}
Modern duct tape is made variously from cotton, [[polyester]], [[nylon]], [[rayon]], or [[fiberglass]] mesh fabric to provide strength. The fabric, a very thin gauze called "[[Scrim (material)|scrim]]", is laminated to a backing of low-density polyethylene (LDPE). The color of the LDPE is provided by various pigments; the usual gray color comes from powdered [[aluminum]] mixed into the LDPE. Two tape widths are common: {{convert|1.9|in|mm|abbr=on}} and {{convert|2|in|mm|abbr=on|0}}. Other widths are also offered.<ref>{{cite book |chapter-url=https://books.google.com/books?id=wt5qQslgpV0C&pg=PA299 |pages=291–331 |last=Smith |first=Jenny M. |chapter=Forensic Examination of Pressure Sensitive Tape |title=Forensic Analysis on the Cutting Edge: New Methods for Trace Evidence Analysis |editor=Robert D.
