Highlights
  • Clear, removable repositionable double-coated tape with a low density polyethylene (LDPE) film liner
  • Slight differential tack with good solvent-resistance
  • Bonds to a variety of substrates
  • Adhesive anchorage to the UPVC film carrier provides one-piece tape removal
  • Complete plastic construction provides a hot wire cut table feature for plastic packaging
  • Can be used for temporary mounting of lightweight materials

The 3M™ Removable Repositionable Tape 666 is a clear, 3.8-mil (0.1 mm) two-sided tape on a white polyethylene liner with equal adhesive strength on both sides for reliable attachment and easy separation for repositioning or multiple openings and closings. Made with a UPVC film carrier, it has medium tack allowing for removal from many films, foils, and papers, and is ideal for applications where repositioning is desired.

Unlike many differential removable/repositionable tapes, the 3M™ Removable Repositionable Tape 666 features a permanent medium tack 3M™ Acrylic Adhesive 400 on the liner side and 3M™ Acrylic Adhesive 1070 on the face side. 3M™ Acrylic Adhesive 400 has good temperature performance and peel strength and is ideal for bonding together a wide variety of similar and dissimilar materials such as metals, glass, wood, papers, paints, and many plastics. 3M™ Repositionable Acrylic Adhesive 1070 holds well to many surfaces and provides easy removal.

Suggested applications
  • Can be used for closing polybags and envelopes, core starting and end tabbing, backlit signs, attaching labels and novelties, posters, and POP displays
  • Ideal for adhering, affixing, mounting, holding, attaching, and temporary positioning of lightweight materials, including paper, plastics, foams, and cardboards
