Brand WK-881 is a TPA-based polyethylene terephthalate (PET) copolymer resin designed for bottle-grade applications. This high molecular weight polymer is widely used in manufacturing containers, including packaging bottles for carbonated soft drinks like cola and large 3-gallon bottles.

Bottles made from WK-881 resin offer excellent optical clarity and gloss, as well as strong barrier properties against oxygen, carbon dioxide, and moisture. The resin also helps prevent bottle cracking during transportation, ensuring product integrity and durability.
