BOPET film, BOPP is also a biaxially oriented film with good mechanical and physical properties .It is a clear, flexible, transparent or translucent material produced from PP polymer, a linear, thermoplastic polypropylene resin. The low density of BOPP (0.91 vs. 1.39 for PET) makes it sometimes a 'cheaper' alternative in packaging usage. However, the advantage of density is offset by the need to typically have a thicker film when using BOPP as compared to PET for the same application. BOPP film is available commercially in a range of widths
