PET Polyester Belt Mylar Tape

Biaxially Oriented Polyester Tape for Wrapping and Insulation

Product Overview

What This Product Is

Mylar tape, also called polyester tape, is made from bi-axially oriented polyester film with high tensile strength and excellent electrical insulation. In cable manufacturing it is the binder and separator: wrapping cores, bundling pairs and insulating internal components so the construction holds its geometry through the next process. It is supplied transparent, slit to 2 mm minimum with 5 mm as the standard width.

Key Benefits

What It Gives Your Production Line

Holds the Core Together

Wrapping and bundling keep pair and core geometry stable before jacketing.

Electrical Insulation Where Layers Meet

Excellent insulation properties allow it to separate conductive layers inside the cable.

High Tensile Strength

Bi-axially oriented film resists stretching under taping tension.

Transparent for Inspection

A transparent tape lets the layer underneath be seen during process checks.

Application Scenarios

Where It Is Used

  • Wrapping cable cores during manufacture
  • Bundling internal components
  • Insulating layers inside multi-core cables
  • Binder tape under shielding layers
Who It Is For

Who Buys It

  • LAN and coaxial cable plants running binder tape heads
  • Multi-core and control cable manufacturers
  • Any producer needing a stable separator layer
Problems It Solves

The Reasons Buyers Move To This Product

Cores Unravel Before Jacketing

A binder wrap holds the lay in place between cabling and extrusion.

Layers Short Against Each Other

Polyester insulation separates shields and conductors inside the construction.

Narrow Tape Breaks Under Tension

Bi-axially oriented film keeps tensile strength even at 2 mm slit width.

Manufacturing And Quality Control

How It Is Produced And Checked

Materials are produced to the stated thickness, width and formulation, then slit, wound and packed to the reel or core size ordered. Dimensional checks are made against the specification before dispatch.

  1. Incoming Material

    Foil, film, compound or wire checked for thickness and surface condition before processing.

  2. Processing

    Coating, lamination, slitting or drawing to the ordered dimension.

  3. Dimensional Check

    Width, thickness and roll or reel diameter verified against the specification.

  4. Performance Reference

    Shielding attenuation and conductivity referenced to the published figures for the grade.

  5. Packing

    Shaft or reel packing in cartons for safe handling and transport.

Customisation Options

What Can Be Changed

  • Slitting width from 2 mm
  • Core bore diameter 52 mm or 76 mm
  • Roll outer diameter up to 800 mm
  • Roll length per shaft
Use Guide

Working With It On Your Line

  • Set binder tension so the tape holds the lay without compressing the pairs.
  • Use the transparent film to confirm the layer beneath during first-article inspection.
  • Store rolls upright on the shaft to protect the edges.
  • Order the slit width against your core diameter and overlap requirement, not the other way round.
