Double-Sided Fiberglass Mesh Tape Jumbo Roll Specifications for Bulk Buyers

Buying double-sided fiberglass mesh tape as a jumbo roll changes the question from “which tape” to “which roll specification”: the master roll width, the running length, the adhesive and carrier system, the thickness, the liner, the core and the packaging, and the converting format that the tape will be slit or rewound into.
A bulk buyer should confirm all of them in writing before the first sample, because each one changes what the converter can produce and what the end application can accept.

For the Broadya mesh tape family, the documented jumbo configuration is a 1050 mm master roll in 1000, 800 or 500 m running lengths, a fiberglass grid carrier with in-house acrylic oil-based adhesive on both faces and a glassine release liner, at documented thicknesses of 100, 150 or 200 microns. These are the configurations currently documented and commonly supplied; they are not a manufacturing boundary. A request for 120 microns, a special width or a different liner goes through a capability check with the supplier rather than being treated as unavailable.

Master Roll Width and Running Length

The two numbers that decide slitting yield and converter cost

The width of the master roll determines how efficiently the converter can slit to the finished widths. On the documented Broadya construction the master roll is 1050 mm wide, which allows clean slitting into common finished widths without excessive edge waste. The running length is equally important: the documented options are 1000, 800 or 500 m per master roll. Bulk buyers who convert in-house should state the width and length combination they want, because it changes roll weight, handling and the number of splices the converter will see.

Carrier and Adhesive System

The two specifications that define what the jumbo roll can do

The carrier and adhesive system are the two specifications that define what the jumbo roll can do. The documented construction uses a fiberglass grid carrier, which provides the tensile strength and dimensional stability that mesh tape is chosen for, and an acrylic oil-based adhesive produced in-house on both faces. For a bulk order, confirm the adhesive system explicitly against the substrate that will be bonded: low-surface-energy plastics and porous materials behave differently from metals, glass or concrete. Do not assume the adhesive from the carrier description; the selection guide covers how to match the adhesive to the substrate pair.

Thickness Options Are Not a Manufacturing Boundary

Documented configurations are a starting point, not a limit

The documented thicknesses are 100, 150 and 200 microns. These are the commonly supplied configurations, not the limit of what can be produced. A bulk buyer with a specific bond line, gap-filling or converting requirement should state the target thickness and treat values outside the documented range as a capability-check item: confirm with the supplier, run a sample, and validate on the actual production line. Thickness changes the bond line and the slitting behavior, so it should be fixed before the jumbo roll is cut.

Liner, Core and Packaging

The details that protect the roll from converting to sea freight

The liner protects the adhesive faces and must be compatible with the converting equipment. The documented construction uses a glassine release liner; confirm the liner type when the tape will be die-cut, kiss-cut or rewound automatically. Also confirm the core inner diameter and material for the jumbo roll, because the converter’s shaft size must match the core. Finally, state packaging and edge protection requirements for the master roll, especially for sea freight, where edge damage during handling is one of the most common causes of waste at the converter.

Converting Format: Slitting and Rewinding

Master roll, slit rolls or rewound lengths — decide before ordering

Decide before ordering whether the jumbo roll will be used for in-house slitting, rewinding, or die-cutting. On the documented program, the master roll can be slit to finished widths and rewound to options such as 50, 30, 25 or 10 m lengths. Each converting route has different tolerances and yields, so the bulk price and the specification table should reference the finished format, not only the master format. For in-house conversion, confirm the master roll spec; for finished rolls, confirm width, length and the number of rolls per carton. The manufacturing process post explains the coating, rewinding and slitting sequence in detail.

How Bulk Buyers Qualify a Supplier

Sample first, measure, then release bulk quantity

A jumbo roll order is a larger commitment than a finished-roll order, so qualify the supplier the same way you would qualify the product: request a representative sample at the exact thickness, width and liner you intend to buy, run it through your actual converting and application process, and measure the key results before releasing a bulk quantity. The sample validation guide gives the test sequence a buyer should run. The product page for the double-sided fiberglass mesh tape lists the documented configurations as a starting point for the specification table.
