Brown PTFE Fiberglass Tape (Brown PTFE Glass Cloth Tape / Brown Heat Sealer Tape

Product Specification

1. Product Overview

Nomay Brown PTFE Fiberglass Tape combines PTFE-coated woven fiberglass cloth with single-sided silicone pressure-sensitive adhesive.

Also known as Brown PTFE Glass Cloth Tape, Brown Heat Sealer Tape or PTFE Fabric Adhesive Tape, it provides a reinforced non-stick surface for heat sealers, packaging equipment, guide rails, rollers and selected hot presses.

This product is the linerless self-wound version. Liner-backed material is a separately specified product format.

2. Product Construction

Working surface: Brown PTFE coating.
Reinforcement: Woven fiberglass cloth.
Adhesive: Silicone pressure-sensitive adhesive.
Adhesive side: Single-sided.
Release liner: None in the standard self-wound roll.
Converting: Custom slitting and fixed-length cutting.

The PTFE coating supplies release properties, the fiberglass provides reinforcement, and the adhesive attaches the tape to equipment.

Overall thickness does not identify the PTFE working-layer or adhesive-layer thickness individually.

3. Backing & Adhesive System

Fiberglass supports dimensional stability and handling strength. The PTFE face helps reduce friction, sticking and buildup of processed materials.

Silicone adhesive supports attachment for appropriately selected heat-processing conditions. Adhesion depends on substrate, pressure, temperature and aging.

The brown shade does not independently identify coating weight, quality or temperature capability. Silicone adhesive does not automatically guarantee residue-free removal.

4. Available Specifications

These are the supplied ordinary-construction family ranges, not a declaration that every size combination is stocked.

5. Key Features & Buyer Benefits

• Non-stick PTFE helps release packaging film.
• Low friction supports material movement over guides.
• Fiberglass reinforces the release surface.
• Self-wound supply supports direct machine installation.
• Replaceable coverage protects expensive contact surfaces.
• Custom widths fit sealing bars and guide geometry.
• Multiple thicknesses support clearance and conformity requirements.
• Reduced buildup can simplify maintenance where the process is compatible.

6. Application Procedure

Step 1 — Identify the machine surface, processed material, contact geometry and installation location.

Step 2 — Select thickness, width, roll length and the required self-wound specification.

Step 3 — Define process temperature, continuous and peak exposure, dwell time, pressure, speed and removal requirements.

Step 4 — Cut strips to the approved dimensions and plan roller seams, overlaps or bar coverage.

Step 5 — Apply to clean, dry surfaces with firm pressure. Avoid stretching, bubbles, wrinkles and unsupported edges.

Step 6 — Validate seal release, adhesion, wear and removal under the actual cycle; adjust equipment settings if thickness changes affect heat transfer.

7. Application Industries

• Flexible packaging and bag making.
• Food and medical packaging equipment.
• Film and paper converting.
• Textile pressing and lamination.
• Printing and coating.
• Plastics processing.
• Composite tooling, subject to process compatibility.
• Machinery maintenance.

8. Application Scenarios / Problems Solved

Heat-Sealing Bars
Cover suitable sealing surfaces to reduce molten-film sticking and residue. Confirm pressure, dwell, actual tape temperature and packaging material. A release tape does not alone guarantee seal strength.

Guide Rails
Provide a low-friction contact surface where film drags or collects residue. Confirm speed, pressure and edge exposure. Abrasive contamination may shorten wear life.

Rollers
Cover suitable rollers handling films, coatings or textiles. Confirm diameter, rotation speed, seam design and cleaning agents. Do not assume one installation pattern suits every roller.

Hot-Press Plates
Use a release layer between compatible processed material and platen. Confirm surface flatness, pressure, temperature and texture requirements. Woven texture may affect the finished surface.

Repeated Sliding
Use replaceable strips to limit direct equipment wear. Confirm load and replacement interval; thicker tape does not automatically provide longer life.

9. Performance & Operating Conditions

Temperature
The supplied temperature capability is 260–300°C, but exposure duration has not been defined. This is not a continuous-service rating. Confirm temperature multiplied by time, cycling, cooling and required service life.

Peel Adhesion
The supplied range is 0–1200 g. Confirm force convention, specimen width, substrate, dwell time and method. The lower endpoint does not establish adequate attachment for every use.

Heat Transfer and Wear
Thickness, coating and pressure affect heat response and release. Inspect for exposed fiberglass, cuts, bubbles and lifting.

Chemicals and Removal
Evaluate complete-tape compatibility with cleaning agents and liquids. Residue-free removal after heat and aging is not guaranteed.

10. Comparison & Selection Guide

Choose this self-wound product for direct equipment installation and routine maintenance.

Choose liner-backed material for precision placement, protected adhesive handling and die cutting.

Choose PTFE film where woven texture is undesirable.

Choose zone tape where adhesive must remain outside the heating center.

Choose thickness by clearance, conformity, heat transfer and tested wear, not an assumed light-duty or heavy-duty label.

11. Important Selection Notes + Technical Notes / FAQ

A. Important Selection Notes

• Confirm size combinations and tolerances.
• The temperature range does not define continuous exposure.
• Peel values require a stated test basis.
• Brown shade does not establish quality or antistatic performance.
• Food-contact requirements apply to the exact finished tape.
• Validate production and removal conditions before bulk use.

B. Technical Notes / FAQ

Does this version have release paper?
No. It is linerless self-wound tape.

Can it continuously operate at 300°C?
That rating has not been established.

Does darker brown mean better performance?
No. Compare the approved construction.

Will a thicker tape last longer?
Not necessarily; coating, load and abrasion also matter.

Can it be used on food-packaging machinery?
It can be evaluated for equipment use; direct food contact requires separate confirmation.
