“WANKAI” Brand WK-851 is a TPA-based polyethylene terephthalate (PET) copolymer resin designed for bottle-grade applications. This high molecular weight polymer is optimized to enhance the reheat blow molding stage in bottle production.
While retaining similar properties to WK-881, WK-851 is characterized by lower energy consumption and higher production rates during bottle manufacturing. Due to a specialized additive, the resin appears darker; however, the final bottles maintain the same clarity as those produced with WK-881.
The following table provides key parameters that define this grade.
Applications:
- Widely used in bottles of all kinds of sparkling beverages and CSD bottles. Carbonated beverage bottles
