The versatility of SANFAME 302 makes it a core material in the Packaging industry:
Water Packaging: It is the industry benchmark for Injection Stretch Blow Molding (ISBM) of mineral water and purified water bottles.
Food Containers: Due to its excellent barrier properties, it is commonly used for edible oil bottles, candy jars, and wide-mouth dried fruit containers.
Personal Care Packaging: Suitable for shampoo and body wash bottles that require high external transparency.
Functional Benchmarking: With its balanced 0.80 I.V. performance, it is ideal for high-speed automated blow molding lines, effectively reducing cycle times and increasing production efficiency.
Helping customers make the most economical and effective choice among similar materials:
| Comparison Dimension | PET 302 (This Product) | PET 502 (Hot-Fill) | PET 602 (Carbonated) |
| Intrinsic Viscosity (I.V.) | 0.80 dL/g | 0.82 dL/g | 0.85 dL/g |
| Performance Focus | Cost-effective, High Transparency | Fast Crystallization, Heat Resistance | High Strength, Internal Pressure Resistance |
| Material Switch Suggestion | Replaces standard grades for better clarity | Replaces 302 for hot-filled tea/juice | Replaces 302 for carbonated drinks |
PET is highly hygroscopic; improper processing can lead to a drop in viscosity (degradation) and yellowing of the product.
Drying Temperature: Recommended drying at 170°C – 180°C.
Drying Time: 4 – 6 hours.
Pro Tip: A Dehumidifying Dryer must be used, ensuring the dew point of the drying air is below -40°C to prevent hydrolysis caused by residual moisture.
Injection Temperature Range: 275°C – 295°C.
Mold Temperature: 10°C – 25°C (Rapid cooling helps maintain the amorphous transparent state of the preform).
In international trade, certification is the cornerstone of trust. Every batch provided by ZiJun Plastics undergoes rigorous quality inspection.
