3M 7000048789 Polyester Film Tape 850 24in X 72yd

Product Description

The 3M 7000048789 is a transparent polyester film tape — 3M Polyester Film Tape 850 — featuring a 1.9 mil polyester film backing with an acrylic adhesive system. At 24 inches wide and 72 yards long, this single roll covers large-area applications without frequent changeovers. The acrylic adhesive delivers strong, stable bonding across a wide temperature range, and the polyester film base resists many common chemicals. Technicians and tradespeople working in industrial, HVAC, electrical, or general facility maintenance environments rely on this tape for splicing, holding, sealing, and surface protection tasks.

This tape suits applications where high optical clarity and dimensional stability matter. Common uses include film splicing, masking during coating operations, sealing packaging or insulation, and protecting surfaces from abrasion or contamination. The transparent film allows inspection of underlying materials without removal. It is appropriate for both light industrial and trade service environments where a chemically resistant, conformable tape is needed on flat or low-contour surfaces.

Key Features

• 1.9 mil polyester film backing provides dimensional stability and puncture resistance
• Acrylic adhesive system offers chemical resistance and broad temperature performance
• High optical clarity allows visual inspection through the tape without removal
• 24 inches wide by 72 yards long — large-format roll reduces splice frequency
• Suitable for splicing, holding, sealing, and surface protection applications

Compatibility

Designed as a general-purpose transparent polyester film tape suitable for splicing, sealing, and protective applications across industrial and trade service environments.

Installation Notes

Apply to clean, dry surfaces free of dust, oil, and loose contaminants for best adhesion. Ensure the substrate is at or above the adhesive manufacturer's recommended application temperature before bonding. When cutting to length, use a sharp blade or dedicated tape dispenser to produce clean edges and avoid delamination. Personnel handling this product in regulated environments should consult applicable safety data sheets before use.
