3M 850

3M Polyester Film Tape 850 is a thin polyester film tape with acrylic pressure-sensitive adhesive for splicing, marking, label protection, masking, and process protection. Its high-strength polyester backing meets low-caliper requirements so the tape can pass through many machinery processes while resisting tearing, abrasion, and rough handling. The acrylic adhesive provides quick stick and long-term holding in splicing applications. Transparent and colored versions are available for different process needs: transparent material provides chemical and solvent resistance, while colored versions improve visibility for marking or identification. The construction is suited to web handling and other operations that require a thin, durable film tape.

Key features

• Low-caliper polyester film: The thin, high-strength backing limits added bulk while resisting tearing and abrasion during machinery and web processes.
• Quick-stick acrylic adhesion: The pressure-sensitive acrylic adhesive provides fast tack and long-term holding for splicing applications.
• Version-specific process options: Transparent material adds chemical and solvent resistance, while colored versions increase visibility for marking and identification.

Applications
