China Resources CR-8863 PET is a bottle-grade polyethylene terephthalate (PET) virgin resin produced by the petrochemical division of China Resources Group, classified as a food-contact grade homopolymer PET resin. The product appears as uniform cylindrical transparent granules, free of black spots and impurities, with stable granule regularity. This grade is a mainstream bottle-grade PET raw material in the domestic packaging industry, featuring balanced physical properties and an acetaldehyde content controlled within the high-end range of the industry, and has been consistently procured by many food packaging manufacturers. The raw material is compatible with the entire processing workflow of preform injection molding and stretch blow molding, and is widely used in the production of packaging containers for drinking water, carbonated beverages, edible oil, and food-grade daily chemicals.

Stable and controllable low acetaldehyde content, ≤1.0 ppm, helps avoid odor and flavor deterioration in beverage packaging, suitable for direct food and beverage contact scenarios.
Moderate intrinsic viscosity range of 0.80-0.84 dl/g provides a broad processing window for stretch blow molding with excellent wall thickness uniformity, suitable for simultaneous production of large-capacity and small-format bottles.
Low dust content ≤100 ppm ensures high raw material cleanliness, significantly reducing the defect rate of black spots and gel particles in finished bottles and minimizing production waste.
Superior color performance with L value ≥80 and b value ≤1.0, providing finished containers with high transparency and no yellowing, enhancing the visual texture of terminal products.
Melting point ≥240℃ indicates excellent thermal stability, resisting degradation during high-temperature injection molding, maintaining stable melt flow during processing, and adapting to high-speed automated blow molding lines.
Stringent moisture control ≤0.2% allows for lower energy consumption during pre-drying, shortens raw material drying time, and reduces overall factory processing costs.
Beverage Packaging Industry: One-way packaging bottles for mineral water, purified water, fruit juice, carbonated beverages, and functional drinks; it is a mainstream PET resin selected by domestic water bottling plants.
Edible Oil and Condiment Packaging: Transparent plastic bottles for soybean oil, rapeseed oil, and olive oil, as well as containers for liquid condiments such as soy sauce and vinegar.
Daily Chemical & Personal Care Packaging: Transparent PET bottles for non-alcoholic toners, lotions, shampoos, and body washes; food-grade daily chemical containers.
Food Container Packaging: Wide-mouth transparent packaging jars and food storage plastic bottles for nuts, candies, honey, jam, etc.
Disposable Packaging Consumables: Food-grade PET preforms, processed into finished products via secondary forming on fully automated blow molding equipment.
Q1: What are the standard drying process parameters for China Resources CR-8863 PET before extrusion/molding?
A: This PET resin has an ex-factory moisture content of ≤0.2% and can be used directly after short-term storage. If the material becomes damp, it is recommended to dry it with hot air at 160°C for 4-6 hours, with the dew point of the drying air controlled below -40°C to avoid hydrolysis-induced silver streaks and bubble defects during injection molding.
Q2: How is CR-8863 PET distinguished from high-viscosity PET grades in packaging selection?
A: CR-8863 has an intrinsic viscosity of 0.80-0.84 dl/g, suitable for standard drinking water, carbonated beverages, and edible oil packaging. High-viscosity PET grades with viscosity above 0.88 dl/g are primarily used for large-capacity water jugs and high-pressure carbonated beverage bottles due to their superior creep resistance; selection should be based on packaging capacity and pressure requirements.
Q3: Does this CR-8863 PET meet international food-contact compliance standards?
A: China Resources CR-8863 bottle-grade PET has passed FDA and EU 10/2011 food-contact material testing and complies with the domestic Chinese GB 4806.7 food-contact plastic standard. Complete TDS, COA, and food-contact test reports can be provided along with orders to meet the compliance requirements for export packaging products.
Q4: What are the storage requirements for this PET raw material?
A: The material is packed in sealed woven bags and should be stored in a dry, cool warehouse with ambient humidity controlled below 60%. Avoid outdoor storage and exposure to rain. Opened but unused resin must be sealed to isolate it from the air, preventing moisture absorption that could affect subsequent forming and processing.
