World famous STA Tapes!
STA's Acrylic Adhesive Tape creates a quick bond to cardboard, and grows stronger over time. It will hold onto carton even when sealed in refrigeration and damp environments. STA's specially formulated adhesive keeps your cartons sealed tight, and keeps them looking fresh and clean (non-yellowing) for a long time. It endures a wide range of shipping hazards, up to very demanding levels. STA Acrylic tape is solvent-free, non-toxic, has low odor, and contains extremely low VOCs and no plasticizer. Unlike some foreign made tapes, it complies to FDA indirect food regulations.
