Wankai PET Bottle Grade WK-821 is a TPA-based polyethylene terephthalate (PET) copolymer engineered for high-performance packaging applications requiring exceptional clarity, mechanical strength, and chemical resistance. Ideal for sparkling beverages, wines, edible oils, and pharmaceutical containers, this premium resin delivers consistent processing performance thanks to its stable intrinsic viscosity (I.V.) and ultra-low acetaldehyde (AA) content (≤1.0 ppm). With a bright L-value of 83.0 and moisture content below 0.2%, WK-821 ensures excellent aesthetics, minimal flavor impact, and reliable production yields in extrusion and injection molding processes.
