PET JADE CZ‑328 CSD Bottles Grade

JADE CZ-328 is a bottle-grade polyethylene terephthalate (PET) resin designed for carbonated beverage packaging and large-capacity containers, including 3-gallon and 5-gallon water bottles. Its material properties make it suitable for packaging applications that require good pressure resistance and structural stability.

With a high intrinsic viscosity, excellent mechanical strength, good gas barrier properties, and low acetaldehyde content, PET CZ-328 supports the production of durable containers with consistent quality. Its favorable processing characteristics also make it suitable for high-speed injection molding and stretch blow molding, including the manufacture of thick-walled bottles.

Main Applications of PET CZ-328

Carbonated Beverage Bottles. JADE CZ-328 is suitable for manufacturing carbonated soft drink bottles and other pressure-resistant beverage containers. Its high intrinsic viscosity and mechanical strength support the production of thick-walled bottle designs, helping maintain container integrity during filling, storage, and transportation.
Large-Capacity Bottles. This grade can be used to produce 3-gallon and 5-gallon water bottles, as well as other large-volume beverage containers. Its mechanical properties and processing characteristics help manufacturers achieve consistent wall thickness, dimensional stability, and sufficient strength for repeated handling and distribution.
Food, Pharmaceutical, and Cosmetic Packaging. In addition to beverage applications, PET CZ-328 can be considered for selected food oil bottles, pharmaceutical containers, and cosmetic packaging. Its transparency and low acetaldehyde content are useful for packaging applications where product appearance and material quality are important. Specific food-contact and pharmaceutical requirements should be verified before use.
PET Sheets and Films. Beyond bottle production, CZ-328 also offers potential for selected PET sheet and film applications. Processors can further convert these materials into thermoformed food trays, transparent packaging containers, and other products that require good clarity and mechanical strength. They can optimize processing conditions according to the target sheet thickness and end-use requirements.

What Is the Difference Between CZ-328 and CZ-328A?

The main difference between the two grades lies in their reheating characteristics. CZ-328 is a standard CSD bottle-grade PET resin suitable for conventional two-step bottle production. In comparison, PET CZ-328A features faster heat absorption during preform reheating, helping shorten heating cycles, increase blowing speed, and reduce energy consumption. Although CZ-328A chips may have a slightly duller appearance, the finished bottles still offer good transparency.

Therefore, JADE CZ-328 is suitable for conventional CSD bottle manufacturing, while CZ-328A is a better choice for producers looking to optimize production speed and energy efficiency.
