BOPET/PET Film
Biaxially oriented PET film is available commercially in a range of widths, thicknesses and properties depending upon the needs of end users. It can be made as a single layer or can be co extruded with other co-polymers into a multi layer film encompassing the desired characteristics of each material.The biaxial orientation of the PET film makes it suitable for such applications as food packaging, electrical insulation, and printing sheets by increasing the product's crystallinity and there by improving its tensile strength, heat resistance, and gas-barrier properties.
