Filament Strapping Tape Guide: Choosing Strength, Width and Construction

Filament strapping tape is built for jobs where ordinary packaging tape may not provide enough reinforcement. Fiberglass strands strengthen the backing, helping the tape resist tearing while bundling, reinforcing and securing loads.

This guide explains how to compare construction, width and pack quantity—and when FIL-795 fiberglass-reinforced filament tape is a practical choice.

What is filament strapping tape?

Filament tape combines a pressure-sensitive adhesive with a reinforced film backing. The fiberglass reinforcement supplies high lengthwise strength, while the adhesive bonds to common packaging surfaces such as fiberboard, plastic and metal.

Common uses include carton closure, box reinforcement, bundling tubes or metal rods, palletizing, unitizing and general holding in packaging or fabrication environments.

Uni-directional vs. bi-directional filament tape

Uni-directional tape places reinforcing filaments primarily along the length of the roll. It is a strong choice when the load pulls in one main direction, as with bundling, strapping or reinforcing a carton seam.

Bi-directional tape adds reinforcement across both directions. Consider it when a package needs cross-directional resistance or when the tape may be stressed from multiple angles. Compare FIL-835B/D bi-directional filament tape with the uni-directional options in our filament tape collection.

Why choose FIL-795?

FIL-795 is a Made in USA, 5.5 mil filament strapping tape with a fiberglass-reinforced polypropylene backing and synthetic rubber adhesive. Its listed tensile strength is 100 lb/in, and each roll is 60 yards long.

• Reinforced construction: fiberglass filaments help the tape resist tears and support demanding packaging tasks.
• Durable backing: polypropylene resists nicks, abrasion, moisture and scuffing.
• Broad surface use: designed to bond to fiberboard, plastic and metal surfaces.
• Multiple widths: choose from 1/2, 3/4, 1, 1.5, 2 and 3 inches, depending on the application and current availability.
• Flexible quantities: selected widths are offered as individual rolls, multipacks and case quantities.

How to select the right width

Choose the narrowest width that safely handles the load after testing on the actual package. Narrow widths are economical for light bundles and carton reinforcement. Wider tape spreads force across a larger surface and may be better for heavier bundles, broader seams or palletized loads.

Because fiberglass-reinforced tape is difficult to tear by hand, plan to use a cutting tool or a compatible dispenser. Apply it to a clean, dry surface and press the tape firmly across the full bond area.

FIL-795 compared with heavier grades

FIL-795 is a versatile 5.5 mil starting point for many packaging and bundling applications. For another 5.5 mil uni-directional option, compare FIL-890. For applications calling for a thicker grade and higher listed strength, review the 7.5 mil FIL-930P. Product thickness alone does not determine suitability, so compare construction, strength, width and surface conditions together.

Application checklist

1. Identify whether the load pulls mainly in one direction or several directions.
2. Estimate the weight and stress the bundle or carton will experience.
3. Choose a width that provides enough contact area.
4. Confirm that the adhesive suits the surface material.
5. Test on the actual package before a full production run.
6. Select the pack or case quantity that matches expected usage.

Frequently asked questions

Is filament tape the same as strapping tape?

Filament tape is often called filament strapping tape or string tape. Its visible reinforcing strands distinguish it from ordinary carton-sealing tape.

Can FIL-795 be torn by hand?

The reinforced tape is tear resistant, so the product page recommends cutting it rather than attempting to tear it by hand.

How long is each FIL-795 roll?

Every FIL-795 option on the product page is 60 yards long.

What width should I order?

The correct width depends on load, surface and application. Test a representative package, then scale to multipacks or cases once the fit is confirmed.
