Berry 444 is a 3.0 mil black OPP film tape with an acrylic adhesive, built for wrapping and protecting foam insulation on HVAC line sets. It is hand tearable, UV resistant for outdoor runs, and rated for -40 to 212 °F, with mold and moisture resistance and low VOC content that can count toward LEED EQ Credit 4.1. Its 45 oz/in adhesion to steel and 32 lb/in tensile strength put it in the same class as other HVAC foil and film tapes, but it is a single-coated film tape, not a butyl or foil-backed flashing tape, so it seals and protects wrap rather than repairing duct joints. It suits HVAC installers and DIYers wrapping outdoor line sets who want a solvent-free, low-odor tape that holds without flagging.
