190% MD Elongation and Low Shrinkage in a 188μm Transparent Polyester Film
Product Overview
This is one of the thickest grades in the BOPET range, and it brings toughness rather than sparkle. At 188μm, elongation at break reaches 190% MD, so the film stretches and absorbs stress instead of tearing. That is useful when it has to survive die-cutting, punching, or repeated mechanical handling. Light transmittance sits at 85.1% with 2.0% haze, giving a clean but not optical-grade finish.
Technical Characteristics
The following values are typical data for the 188μm specification. They are not intended as limiting specifications.
- Material: BOPET (Biaxially Oriented Polyethylene Terephthalate)
- Thickness: 188 μm
- Light Transmittance (550nm): 85.1%
- Haze: 2.0%
- Tensile Strength: MD 186 MPa / TD 196 MPa
- Elongation at Break: MD 190% / TD 140%
- Thermal Shrinkage at 150°C, 30min: MD 0.9% / TD 0.5%
- UL746B: RTI Electrical 105°C, Mechanical 105°C
Key Properties
- High elongation for tough converting and die-cutting
- Low MD shrinkage for dimensional control
- Thick gauge that holds up to repeated mechanical handling
- Clean appearance for graphic and lamination work
Applications
188μm 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.
