JADE CZ-302L PET

1. What is JADE CZ-302L mainly used for?

JADE CZ-302L is primarily used for lightweight PET bottles, thin-wall beverage containers, PET preforms, disposable transparent food packaging, and applications requiring reduced resin consumption with excellent processing performance.

2. What is the intrinsic viscosity of CZ-302L?

The typical intrinsic viscosity is approximately 0.76 dL/g, providing improved melt flow compared with standard IV 0.80 bottle-grade PET resin while maintaining good transparency and bottle quality.

3. Why is lower IV beneficial for lightweight bottles?

Lower intrinsic viscosity improves resin fluidity during injection molding, allowing manufacturers to produce thinner preforms more efficiently and achieve lightweight bottle designs with stable dimensional consistency.

4. Can CZ-302L be used for mineral water bottles?

Yes. It is suitable for lightweight mineral water and purified drinking water bottles, particularly where manufacturers prioritize reducing bottle weight and overall PET material consumption.

5. Is JADE CZ-302L suitable for carbonated beverage bottles?

Generally, no. High-pressure carbonated soft drink bottles usually require higher-strength PET resin grades such as JADE CZ-328, which offer better pressure resistance and mechanical performance.

6. How does CZ-302L reduce manufacturing costs?

Its improved melt flow allows thinner bottle designs, lower resin consumption, potentially shorter molding cycles, and reduced transportation weight, helping manufacturers improve overall production efficiency and profitability.
