Brand WK-901 is a TPA-based polyethylene terephthalate (PET) copolymer resin designed for bottle-grade applications. This high molecular weight polymer is ideal for general container production, particularly large-volume bottles such as edible oil containers, water bottles, and 5-gallon big bottles.

Bottles produced from WK-901 exhibit excellent optical clarity and gloss, along with strong barrier protection against oxygen, carbon dioxide, and moisture. The resin also helps prevent bottle cracking during transportation, ensuring durability and maintaining product integrity.
