BOPET Film: High Transparency for Graphic Arts, Labels, and Membrane Switches

Why Optical Clarity and Consistent Haze Matter in Transparent Polyester Film

Product Overview

Not every polyester film is made to be seen through. BOPET Film is a high-transparency biaxially oriented PET film engineered for applications where optical clarity matters as much as mechanical strength. With high light transmittance and low haze, it gives graphic arts, label, and membrane switch producers the clean, uniform base they need for sharp imaging and reliable lamination.

Technical Characteristics

The following values are typical data across the standard thickness range from 25μm to 250μm. They are not intended as limiting specifications.

  • Material: BOPET (Biaxially Oriented Polyethylene Terephthalate)
  • Thickness range: 25 μm to 250 μm
  • Light Transmittance (550nm): 85–89%
  • Haze: 0.6–3.0% depending on gauge
  • Tensile Strength: MD 176–225 MPa / TD 186–245 MPa
  • Thermal Shrinkage at 150°C, 30min: MD 0.9–1.3% / TD 0.0–0.6%
  • UL746B: RTI Electrical 105°C, Mechanical 105°C

Key Properties

  • High light transmittance for clear optical performance
  • Low haze for crisp printing and imaging
  • Flat and uniform surface for consistent lamination
  • Stable thermal shrinkage across thicknesses
  • Good mechanical strength for converting and handling

Applications

BOPET Film is used as a base film for graphic arts and layout, flat-face release, membrane switches, labels, OHP sheets, printing and lamination, and any application requiring high transparency of PET film.

Target industries include printing and graphic arts, electronics, label and packaging, and general converting.
