CZ-328H is a TPA-based polyethylene terephthalate (PET) copolymer engineered for general container production. Its high molecular weight makes it particularly suitable for manufacturing large bottles, including 3-gallon and 5-gallon sizes.

This grade is characterized by low heavy metal content, minimal acetaldehyde levels, excellent color clarity, stable viscosity, and reliable processability. Produced using a proprietary process and advanced technology with enhanced process control and quality management, CZ-328H enables low-temperature processing, broad processing flexibility, excellent transparency, and high strength, making it ideal for demanding container applications.
