CZ-328 is a TPA-based polyethylene terephthalate (PET) copolymer engineered for general container production. With its high molecular weight, this polymer is ideal for manufacturing packaging bottles for carbonated soft drinks, including cola, as well as large-capacity bottles of 3 and 5 gallons.

This grade is distinguished by low heavy metal content, minimal acetaldehyde levels, excellent color clarity, and stable viscosity, ensuring consistent and reliable processing. Produced using a proprietary process and advanced technology with enhanced process control, CZ-328 offers superior barrier properties to prevent carbon dioxide loss.

The material demonstrates high pressure resistance, suitability for low-temperature processing, broad processing versatility, excellent transparency, and high finished product yield. Additionally, CZ-328 effectively reduces bottle breakage during storage and under pressure, making it a highly dependable choice for carbonated beverage packaging.
