Adhesive Tape 3M FE510049052 – Transparent Polyester, 66 m × 19 mm

3M FE510049052 is a transparent polyester adhesive tape with a length of 66 m and a width of 19 mm. This clear polyester tape is designed to provide a neat, virtually invisible finish for sealing, splicing, reinforcing and general-purpose applications where transparency and dimensional stability are important. The tape combines a stable polyester backing with an adhesive formulated for consistent tack and adherence to a variety of clean, dry surfaces, making it suitable for packaging, surface protection, light-duty joining and situations requiring repeatable application lengths.

Advantages

The transparent polyester backing delivers good dimensional stability and resistance to stretching, ensuring consistent application widths. The clear appearance minimizes visual impact while maintaining useful mechanical strength for light reinforcement and splicing. The adhesive is balanced to provide reliable tack and holding power on paper, cardboard, plastics and coated surfaces without excessive residue when applied under recommended conditions. The roll format and standard 19 mm width allow easy handling and controlled dispensing for repetitive tasks.

Suitable for

• Sealing and closing lightweight packages and envelopes
• Splicing films, foils or paper in production or repair tasks
• Surface protection for visible areas where transparency is required
• Light-duty joining, reinforcement or tabbing of components
• General-purpose masking of small areas during finishing or assembly

Key specifications

• Backing material: transparent polyester film
• Adhesive type: pressure-sensitive adhesive formulated for general-purpose use
• Length: 66 m
• Width: 19 mm
• Appearance: clear / transparent
• Typical uses: sealing, splicing, reinforcing, surface protection

How to use

Ensure the surfaces to be bonded or protected are clean, dry and free of dust, oils or other contaminants. Cut or tear the tape to the required length, position the tape carefully and press firmly to ensure full contact between the adhesive and substrate. For splicing or reinforcement, align edges precisely before applying pressure. For repeated use, dispense from the roll using a suitable dispenser or manual application, keeping the roll stored in a dry environment to preserve adhesive performance.

Recommendations

Use on clean, dry surfaces and avoid prolonged exposure to high humidity or temperatures above typical indoor conditions to maintain adhesive properties. For critical applications or long-term outdoor use, test adhesion on the actual substrate first. Store the product in its original packaging at room temperature and use within the manufacturer’s recommended shelf life for optimal performance.
