WBP-12RT is a transparent PET film with a silicon oxide (SiOx) barrier layer. It combines optical clarity with oxygen and water-vapor barrier performance for transparent laminated packaging evaluation.

The technical data report typical OTR of 0.32 cc/(m²·day) at 23°C and 0% RH, and WVTR of 0.35 g/(m²·day) at 38°C and 90% RH. Reference thickness is 12.5 μm.

The functional surface has a typical wetting tension of 54 mN/m and is designated for printing. Printing and lamination conditions should be confirmed through converting trials.
