3M 7100043788 Woven Patch Tape 3.89in X 55yd White

Product Description

The 3M 7100043788 is a woven patch tape designed for seaming, repairing, bonding, patching, and reinforcing difficult-to-bond materials. Built on a high-tack adhesive with a durable woven backing, this tape bonds quickly and holds firmly under demanding conditions. The white woven construction is engineered to match standard white woven insulation facings for a clean, seamless appearance. The backing elongates up to 30 percent, allowing it to conform during challenging wrap and bundle applications without tearing. This tape is suited for trade and industrial use wherever polyethylene, polypropylene, or woven fabric substrates require a strong, lasting repair or seam.

This tape is used across agricultural, industrial, and construction applications. Common uses include patching and repairing polyethylene and polypropylene bulk bags, tarps, and woven fabrics, reinforcing cotton bales and bundles of lumber, bonding agricultural films, and seaming greenhouse covers. The woven face matches white insulation facings, making it a practical choice for HVAC insulation repair and seaming work where appearance and durability both matter.

Key Features

• High-tack adhesive bonds quickly to polyethylene, polypropylene, and woven substrates
• Woven backing matches white woven insulation facings for a seamless finish
• Backing elongates up to 30 percent to handle uneven edges and irregular surfaces
• Durable construction resists tearing during bundling and patching tasks
• Suitable for greenhouse seaming, agricultural film bonding, and tarp repair

Compatibility

Designed for use on polyethylene and polypropylene fabrics, bulk bags, tarps, woven insulation facings, agricultural films, and similar hard-to-bond woven or film-based substrates.

Installation Notes

Surface preparation is critical — clean and dry the substrate before applying to ensure full adhesive contact. Apply firm, even pressure across the full tape width to activate the adhesive bond. In HVAC insulation seaming applications, follow manufacturer guidelines and applicable mechanical codes for duct insulation repair. Store unused rolls away from direct sunlight and extreme temperatures to preserve adhesive performance.
