Shanghai Yunshan Plasticizing Co., Ltd. is proud to offer SABIC PP QR678K, a high-flow, transparent polypropylene granule specifically engineered for thin-wall household container production. As a trusted supplier based in Shanghai, China, we deliver consistent quality and reliable supply to manufacturers worldwide. This advanced PP grade combines exceptional flowability with crystal clarity, enabling faster cycle times and superior aesthetic finishes in applications such as food storage boxes, lids, and disposable cups.
SABIC PP QR678K is a random copolymer with a balanced molecular weight distribution that ensures excellent impact resistance while maintaining high stiffness. Its high melt flow rate (MFR) allows it to fill complex thin-wall cavities rapidly, reducing injection pressure and clamp force requirements. The material exhibits outstanding transparency and gloss, meeting the visual demands of modern household containers. Additionally, it offers good chemical resistance and low odor, making it suitable for contact with food items (subject to local regulations).
Key Features & Benefits
- High Flowability: MFR typically ≥30 g/10min (230°C/2.16kg) enables thin-wall molding (0.3–0.8 mm) with reduced cycle time by up to 20%.
- Excellent Transparency: Haze below 15% and high gloss (≥95 at 60°) for premium product appearance.
- Good Mechanical Balance: Combines high stiffness (flexural modulus ≥1200 MPa) with impact strength (Izod notched ≥5 kJ/m²) for durability.
- Processing Efficiency: Wide processing window (melt temperature 200–240°C) and low shrinkage (1.2–1.6%) ensure dimensional stability.
- FDA & EU Compliance: Meets requirements for food contact applications (certificates available upon request).
- Consistent Purity: Low gel level and no black specks guarantee high-quality finished parts.
Typical Technical Specifications

|---|---|---|---|
| Melt Flow Rate (230°C/2.16kg) | ≥30 | g/10min | ISO 1133 |
| Density | 0.900–0.905 | g/cm³ | ISO 1183 |
| Flexural Modulus | ≥1200 | MPa | ISO 178 |
| Izod Notched Impact (23°C) | ≥5 | kJ/m² | ISO 180 |
| Haze | ≤15 | % | ISO 14782 |
| Shrinkage (Mold) | 1.2–1.6 | % | ISO 294 |
The combination of high flow and transparency makes SABIC PP QR678K an ideal raw material for thin-wall injection molding. Manufacturers benefit from faster cycle times (reduced by 10–20% compared to conventional PP), lower energy consumption due to reduced injection pressure, and the ability to produce intricate designs with uniform wall thickness down to 0.3 mm. The natural clarity of the granule eliminates the need for additional polishing or coating in many applications, saving secondary processing costs.
For end-users, containers made from QR678K offer a premium look and feel. The high gloss surface resists scratching and maintains its appearance after repeated washing. Good thermal resistance (Vicat softening point ~150°C) allows microwave and dishwasher use. The material also provides a barrier against grease and moisture, extending the shelf life of stored contents.

Frequently Asked Questions (FAQ)
-
Q: Is SABIC PP QR678K suitable for food contact applications?
A: Yes, this grade is formulated to comply with food contact regulations such as FDA and EU Directive 10/2011. Certificates are available upon request. However, we recommend that customers perform their own compliance testing for specific end-use conditions. -
Q: What is the typical processing temperature range?
A: The recommended melt temperature is between 200°C and 240°C. Mold temperature of 20–40°C is typical. High flowability allows lower injection pressures, reducing stress in thin-wall parts. -
Q: Can this material achieve a fully transparent effect?
A: Yes, with proper mold design and processing conditions, the haze can be below 15%, providing excellent clarity. The natural color is water-clear. -
Q: What is the minimum wall thickness achievable?
A: Thanks to the high MFR, wall thicknesses as low as 0.3 mm can be molded, depending on part geometry and processing parameters. -
Q: Is it compatible with common pigments or masterbatches?
A: Yes, QR678K is compatible with most PP-compatible colorants. However, we suggest performing a trial to verify color dispersion and mechanical property retention. -
Q: How is the product packaged and shipped?
A: Standard packaging is 25 kg polywoven bags with PE liner. We also offer 500 kg octabins or 1-ton big bags. All shipments are from Shanghai, China, with lead times typically 7–15 days after order. -
Q: Do you provide free samples?
A: Yes, we offer free small samples (500g–1kg) for evaluation. Please contact our sales team with your application details. -
Q: What is the shelf life of this material?
A: When stored in a cool, dry place away from direct sunlight, the material can be used for up to 24 months from the date of manufacture without significant degradation.
