JADE CZ-328 PET
JADE CZ-328 PET, CZ-328A PET are TPA-based polyethylene terephthalic copolymer. It is a high molecular weight polymer for general use in manufacturing containers. It can be used in the production of making packing bottles for carbonated soft drink like cola and 3-gallon, 5-gallon big bottles.
Compared with standard bottle-grade PET designed primarily for still water, CSD packaging requires a different balance of properties. The bottle must withstand internal pressure created by dissolved carbon dioxide while maintaining dimensional stability, transparency and resistance to stress cracking throughout its service life.

Key Advantages of JADE CZ-328 PET Resin
>> Suitable for Carbonated Beverage Packaging
The primary application of CZ-328 is the production of bottles for carbonated soft drinks such as cola and other soda beverages.
>> High Intrinsic Viscosity
CZ-328 has an IV specification of 0.850 ± 0.02 dL/g. This relatively high IV helps provide the molecular weight and melt strength required for demanding bottle applications.
>> Improved Resistance to Stress Cracking
Stress cracking is a critical concern for pressurized PET bottles. JADE product information specifically highlights resistance to stress and cracking as a performance characteristic of CZ-328.
>> Good CO2 Retention Characteristics
CSD bottles must retain carbonation during their intended shelf life. CZ-328 is marketed with favorable barrier properties intended to help reduce CO2 loss.
>> Excellent Transparency
The published specification includes an L color value of ≥82 and b value of ≤1, supporting clear and visually attractive bottles.
>> Stable Processing
The product documentation emphasizes stable viscosity, good processability, a broad processing range and relatively low processing temperature.
FAQs About JADE CZ-328 PET Resin
1. What is JADE CZ-328 PET resin mainly used for?
JADE CZ-328 is primarily designed for bottle production for carbonated soft drinks, including cola and soda beverages. It is also suitable for 3-gallon and 5-gallon large PET bottles.
2. What is the intrinsic viscosity IV value of JADE CZ-328?
The current JADE CZ-328 specification lists an intrinsic viscosity of 0.850 ± 0.02 dL/g. Buyers should confirm the final shipment against the current manufacturer’s TDS and batch-specific COA.
3. Why is CZ-328 PET suitable for carbonated soft drink bottles?
CSD bottles must withstand internal pressure and maintain mechanical integrity during storage. JADE CZ-328 PET is specifically positioned for this application and is described as having favorable barrier properties and improved resistance to stress and cracking.
4. What is the difference between JADE CZ-328 and CZ-302?
CZ-302 is primarily associated with still-water and general water bottle applications, while CZ-328 is specifically designed for more demanding CSD packaging. CZ-328 also has a higher specified IV of 0.850 ± 0.02 dL/g.
5. Can CZ-328 be used for cola bottles?
Yes. Cola and other carbonated soft drink bottles are among the principal applications identified for JADE CZ-328. The grade is designed for bottle applications where pressure resistance and carbonation retention are important.
6. Can JADE CZ-328 be used for 5-gallon PET bottles?
Yes. JADE product information specifically identifies 3-gallon and 5-gallon large bottles as applications for CZ-328, making it suitable for manufacturers producing large-capacity PET containers.
7. Can PET CZ-328 be used for mineral water bottles?
It can be processed into PET bottles, but its principal positioning is carbonated beverage packaging and large bottles. For conventional still mineral water bottles, buyers may also consider JADE CZ-302 or other water-bottle grades.
