Huarun CR-8828 | Low Acetaldehyde Content & Stable Viscosity for Carbonated Beverage Packaging
Product Overview
Huarun CR-8828, specifically the PET CR-8828, is a remarkable bottle-grade PET resin developed by Huarun Polyester (Changzhou) Co., Ltd. Polyethylene terephthalate (PET) is one of the most widely used thermoplastics globally, and CR-8828 stands out in the market due to its balanced comprehensive properties. With the increasing demand for high-quality food-contact packaging materials, especially in the food and beverage industry, this resin is engineered to meet strict international food safety and blow molding standards. It supports mainstream processing techniques including injection preform molding and stretch blow molding for carbonated beverage plastic bottles. Consistent batch quality and stable supply chain enable continuous mass production for packaging manufacturers of all scales.

Core Product Advantages
Low Acetaldehyde and Excellent Food Safety
The CR-8828 PET resin has an extremely low acetaldehyde content below 1.0 ppm. Acetaldehyde is an odor-causing substance that affects beverage flavor in food-contact applications. In carbonated beverage bottle production, low acetaldehyde avoids off-flavor transfer to drinks and fully retains the original taste of beverages. This low-acetaldehyde characteristic complies with global food safety regulations including US FDA standards, delivering safe packaging solutions for food and beverage manufacturers without flavor contamination risks. Manufacturers can apply this resin confidently without worrying about compromising end-product taste quality.
Stable Viscosity for Consistent Processing
Stable intrinsic viscosity is a core characteristic of Huarun CR-8828. During PET injection preform and blow molding processes, consistent IV delivers uniform melting and stable melt flow. It produces finished bottles with even wall thickness, standardized shape and stable physical performance. On high-speed automatic production lines, steady viscosity effectively reduces common defects such as uneven wall thickness, bottle neck deformation and bottle bursting. Manufacturers achieve higher production yield, less raw material waste and lower overall manufacturing costs. This reliable processing performance fits both small-batch trial production and large-scale continuous mass manufacturing.
Good Transparency and High Yield
Products molded from Huarun CR-8828 deliver outstanding high-gloss transparency. This core advantage is highly valued in packaging, allowing consumers to clearly view the contents inside bottles. For carbonated drinks, crystal-clear packaging highlights beverage color and bubbles to boost shelf visual appeal and consumer purchase intention. Meanwhile, the proprietary polymerization formula minimizes gel specks and black impurities during molding to lift qualified finished product rate. Manufacturers gain more certified bottles with the same raw material input to improve overall economic benefits.
Moderate Melting Temperature with Wide Processing Window
CR-8828 features moderate melting temperature with an extra-wide processing temperature range (265–285°C). Optimized processing temperature cuts heating energy consumption during production to lower manufacturing costs and reduce carbon emissions. The broad temperature tolerance provides flexible adjustment space for different blow molding equipment; minor temperature fluctuation will not damage resin performance. This processing flexibility simplifies production line optimization and lifts overall production efficiency.
Main Application Fields
- Carbonated beverage packaging: Core application for carbonated soft drink bottles, supported by ultra-low acetaldehyde and stable blow molding performance.
- Food packaging: Suitable for food jars, fruit juice bottles and transparent food storage containers, compliant with international food-contact standards and featuring high transparency.
- General transparent packaging: Applicable to all food-grade transparent packaging requiring stable melt performance and low odor.
Processing & Storage Guidelines
Processing: Use hot air drying equipment to dry PET pellets at 160–170°C for 4–6 hours before molding to control moisture content below 0.005%. Adjust barrel temperature within the recommended 265–285°C range according to your injection/blow molding equipment. Maintain stable screw pressure and rotation speed during production to eliminate bottle defects.
Storage: Store resin in a dry, cool, well-ventilated warehouse. Keep away from direct sunlight, heat sources and humid surroundings. Storage temperature range: 10–30°C, relative humidity below 70%. Leave ventilation gaps between stacked bags to prevent pellet caking.
