Avery Dennison™ FT 7346 – Ultra-Thin Double Coated Polyester Tape
Product Overview:
Avery Dennison™ FT 7346 is an ultra-thin double coated polyester tape designed for high-precision mounting applications. Featuring modified acrylic adhesives on both sides and a moisture-stable liner, FT 7346 delivers excellent adhesion to a wide range of substrates, including low surface energy materials. Its thin profile and clear adhesive make it ideal for applications where size and thickness reduction are critical, without compromising bond strength or reliability. The tape also offers high temperature and UV resistance, excellent die-cutting properties, and ease of removal at the point of application.
Key Features
Modified Acrylic Adhesive: Provides consistent adhesion and durability.
Clear Adhesive: Ensures high transparency for aesthetic and functional applications.
Thin Polyester Carrier: Maintains dimensional stability and strength.
Good Converting Properties: Optimized for die-cutting, laminating, and other processing operations.
Easy-Release Liner: Facilitates smooth handling and precise application.
Benefits
High temperature and UV resistance for long-term performance.
Maintains a high degree of transparency for unobtrusive bonding.
Adheres effectively to a variety of substrates, including low surface energy materials like polypropylene.
Provides exceptional stability and clean die-cutting capabilities.
Allows easy removal during application without leaving residue.
Suitable for applications where tape thickness and size minimization are essential.

Application Techniques
Surfaces must be clean, dry, and free of grease or oil before application.
Bond strength depends on pressure, dwell time, and surface contact.
Performance may vary depending on surface type, rigidity, and temperature conditions.
Storage and Shelf Life
Store in original packaging at 64–72°F (18–22°C) and 30–70% relative humidity, out of direct sunlight.
Shelf life is up to two years under recommended conditions.
