Huarun CR-8863 | High Transparency & Low Acetaldehyde Content for Food Packaging
Product Overview
Huarun CR-8863 is a high-quality bottle grade PET (Polyethylene Terephthalate) resin. PET is a well-known and widely used polymer in the packaging industry. Huarun, a reputable manufacturer, has developed this specific grade to meet the strict requirements of food packaging. This resin is designed to be used in the production of various types of bottles, such as water bottles, oil bottles, and beverage bottles. It offers a combination of excellent physical and chemical properties. With its high transparency, it allows consumers to clearly see the contents inside the bottle. The low acetaldehyde content ensures that the flavor and quality of the packaged food or beverage are not affected. The stable intrinsic viscosity provides consistent processing performance during the manufacturing process, whether it is injection preform molding or stretch blow-molding. Moreover, it has good mechanical strength and gas barrier properties, which help to protect the contents from external factors like oxygen, moisture, and light. This makes Huarun CR-8863 a reliable choice for food and beverage manufacturers who are looking for a high-quality packaging solution.

Core Product Advantages
High Transparency
The high transparency of Huarun CR-8863 is one of its most significant advantages. In the food packaging industry, transparency is crucial as it allows consumers to directly observe the quality and quantity of the product inside the bottle. For example, in the case of water bottles, clear visibility gives consumers a sense of freshness and purity. Moreover, for high-end food products like premium olive oil or fine wines, the high-quality transparency of the bottle enhances the overall aesthetic appeal, making the product more attractive on the shelves. This transparency is achieved through advanced manufacturing processes and high-quality raw materials, ensuring that there are no cloudiness or impurities in the final product.
Low Acetaldehyde Content
Acetaldehyde is a chemical compound that can have a negative impact on the taste and odor of food and beverages. Huarun CR-8863 has an extremely low acetaldehyde content, which is a major benefit for food and beverage manufacturers. This low content ensures that the flavor of the packaged product remains intact. For instance, in the production of carbonated drinks, a low acetaldehyde content prevents the development of off-flavors, allowing the drinks to maintain their original taste. It also meets the strict food safety standards, ensuring that the packaged food and beverages are safe for consumption. This is achieved through precise control of the production process and the use of high-purity raw materials.
Stable Viscosity
Stable intrinsic viscosity is essential for consistent processing during the manufacturing of bottles. Huarun CR-8863 offers stable intrinsic viscosity, which means that the resin flows evenly during injection molding or blow-molding processes. This leads to a more uniform wall thickness of the bottles, reducing the risk of defects such as thinning or cracking. In mass-production scenarios, this stability improves the production efficiency and reduces the scrap rate. For example, when producing large-scale batches of water bottles, the stable viscosity ensures that each bottle has the same quality and performance, which is crucial for meeting market demand and maintaining a good brand image.
Good Processing Performance
Huarun CR-8863 has excellent processing performance, with a moderate melting temperature and a wide processing window. This allows manufacturers to save energy during the production process. The wide processing range also gives more flexibility in adjusting the production parameters according to different production requirements. For example, in different seasons or production environments, manufacturers can easily adjust the processing conditions to ensure the quality of the final product. Additionally, the high transparency and high finished product rate of the processed bottles further demonstrate its good processing performance.
Main Application Fields
- Food Packaging: Mineral water bottles, distilled water bottles, edible oil bottles, soy sauce bottles, normal-temperature beverage bottles, etc.
- Other Packaging: Transparent PET sheets and other food-contact packaging containers.
Processing & Storage Guidelines
Processing: Before injection molding, the resin must be fully dried. The recommended drying temperature is 160–170°C, and the drying time is 3–4 hours to control moisture content below 0.005%. The barrel melt temperature is 245–260°C, nozzle temperature 240–255°C, front zone 245–260°C, middle zone 240–255°C, rear zone 230–250°C, mold temperature 50–75°C, back pressure 0.3–0.7 MPa.Storage: The resin should be stored in a dry and cool place, away from direct sunlight and moisture, to prevent the resin from absorbing moisture and affecting its processing performance and finished product transparency.
