TL;DR
Flashing tape is self-adhered waterproofing membrane in roll widths of 4 to 12 inches — acrylic, butyl, or asphalt adhesive on a tough facer — used to seal window and door openings, deck ledgers, sheathing seams, and penetrations into the wall's drainage plane. Application order is everything: pieces lap shingle-style, sill first, jambs over sill, head last, so each sheds onto the one below.

Acrylic versions bond in cold weather and stick to damp surfaces better; AAMA 711 is the listing spec window manufacturers cite.
