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

Bottles produced from WK-901 resin offer excellent optical clarity and gloss, along with strong barrier properties against oxygen, carbon dioxide, and moisture. Additionally, the resin helps prevent bottle cracking during transportation, ensuring product integrity.
