3M 7000048378 Polyester Splicing Tape 1in X 72yd Black

Product Description

The 3M 7000048378 is a black polyester film splicing tape designed for pre-splicing photographic film ahead of processing runs. Built on a 2.5 mil polyester film backing, it uses a high-tack rubber adhesive that bonds quickly to film surfaces and holds through the demands of automated processing equipment. At 1 inch wide and 72 yards long per roll, the tape delivers a consistent supply for busy lab and processing environments. The combination of a dimensionally stable polyester carrier and aggressive rubber adhesive also makes this tape suitable for sealing, labeling, protecting, and edging applications where a firm, reliable bond is required.

This tape is primarily used in photographic film processing facilities where pre-splicing film rolls is a standard workflow step before automated development. Beyond that core application, it performs in industrial and light-commercial settings requiring a conformable, opaque black tape with strong tack. Typical installers and users include photo lab technicians and production line operators who work with roll-fed film or similar web materials. The 1-inch width suits standard splicing jigs and hand application without trimming.

Key Features

• 2.5 mil polyester film backing provides dimensional stability and tear resistance
• High-tack rubber adhesive bonds firmly to photographic film and similar substrates
• Black opaque finish suitable for light-blocking and edging applications
• 1 inch wide by 72 yards long per roll for extended use between changeouts
• Versatile secondary uses: sealing, labeling, protecting, and edging

Compatibility

Designed as a pre-splicing tape for photographic film processing equipment that accepts standard 1-inch splicing tape rolls. Also suited for general sealing, labeling, and edging tasks where a high-tack rubber-adhesive polyester tape is appropriate.

Installation Notes

This tape is applied by hand or with a standard splicing jig; no tools beyond a cutting edge or dispenser are typically required. Ensure the film or substrate surface is clean and dry before application to achieve full adhesive contact. When used in processing equipment, verify that the splice thickness is within the machine manufacturer's tolerance before running. Store unused rolls in a cool, dry location away from direct light to preserve adhesive performance.
