CZ-328 is a TPA-based polyethylene terephthalate copolymer designed for general use in manufacturing containers. This high molecular weight polymer is ideal for producing packaging bottles for carbonated soft drinks such as cola, as well as large bottles of 3-gallon and 5-gallon capacity. The product features low heavy metal content, low acetaldehyde levels, excellent color clarity, and stable viscosity, ensuring good processing performance. Utilizing a unique process recipe and advanced production technology with enhanced process control and quality management, CZ-328 provides excellent barrier properties to effectively prevent carbon dioxide leakage.

It exhibits strong pressure resistance, suitability for low-temperature processing, broad processing versatility, excellent transparency, and a high finished product yield. CZ-328 also effectively prevents bottle breakage during storage and under pressure, making it highly reliable for carbonated beverage packaging.
