Definition
Filament tape is a type of pressure-sensitive adhesive tape reinforced with continuous filaments, typically made of fiberglass or synthetic fibers, designed to provide high tensile strength and durability for packaging, sealing, and reinforcing applications.
Overview
Filament tape is commonly used in industrial and commercial settings for box sealing, bundling, and reinforcing cartons, especially those that are heavy or subject to stress during handling and transportation. It is valued for its ability to resist tearing and maintain adhesion under varying environmental conditions. The tape is usually applied using a manual tape dispenser or automated taping equipment. It is often used as an alternative to strapping in certain packaging applications. Popular applications include securing corrugated boxes, reinforcing joints, and providing tamper resistance.
Etymology/Origin
The term "filament tape" derives from "filament," referring to the thin, thread-like reinforcing fibers embedded in the tape's backing, and "tape," a general term for a narrow strip of material with an adhesive coating. The development of filament-reinforced tapes emerged during the 20th century with advances in adhesive and synthetic fiber technologies, particularly after the introduction of materials such as filamentary fiberglass and polypropylene.
Characteristics
- Reinforcement: Contains continuous filaments (often fiberglass) embedded in or laminated to a plastic film backing (e.g., polypropylene or polyester).
- Adhesive: Typically features an acrylic or rubber-based adhesive offering good adhesion to various surfaces.
- Tensile Strength: High resistance to breaking under tension due to embedded filaments.
- Application: Used with a dispenser that applies tension, allowing the filaments to stretch and lock into place.
- Width and Length: Commonly available in widths from 1/2 inch to 2 inches and on rolls of standard lengths (e.g., 100–200 yards).
- Variants: Available in various grades based on filament count per inch (e.g., 6, 9, or 12 filaments per inch), influencing strength and application suitability.
