The present invention relates to a process of manufacturing bi-axially oriented polyester film directly from the polymer melt. More particularly, the said process minimises the waste generated in the process and/or to reuse the waste. The present process is capable to produce single or multilayer bi-axially oriented...

The present invention relates to a biaxial oriented polyester film and process for preparing the same, the said film is having an average ellipticity of not more than 0.6, Poisson ratio of not more than 0.7 (at elongation greater than 25%) all along the width of web and residual enthalpy in the range of 12 % to 20 %...

The present disclosure relates to a process for producing bi-axially oriented polyester (BOPET) film from the PCR Polyethylene Terephthalate (RPET) granules. The present process is capable to produce single or multilayer bi-axially oriented polyester film having uniform thickness. The RPET film product having si...
