Shanghai Yunshan Plasticizing Co., Ltd. is proud to offer SABIC PP 621P Random Copolymer Cast Film Pellets — a premium-grade raw resin specifically engineered for high-clarity food packaging applications. As a trusted distributor of SABIC materials, we supply this high-performance random copolymer polypropylene that delivers outstanding optical transparency, consistent processing characteristics, and reliable mechanical strength. Whether you produce cast films for flexible packaging, lamination, or thermoforming, our SABIC PP 621P helps achieve superior film quality with excellent sealability and stiffness.
This resin is designed to meet the demanding requirements of modern food packaging: it offers exceptional clarity for product visibility, low haze values, and good gloss. With a controlled melt flow rate, it ensures smooth extrusion and stable film formation, reducing downtime and waste. Additionally, the random copolymer structure provides improved impact resistance and flexibility compared to homopolymer PP, making it ideal for packaging that requires both strength and transparency.

Product Advantages for Food Packaging
- High Clarity & Low Haze: Achieve glass-like transparency that enhances product shelf appeal and allows consumers to see the contents clearly.
- Excellent Sealability: Random copolymer structure provides a wide sealing window and strong heat seal strength, ensuring package integrity.
- Good Processability: The optimized MFR (8 g/10 min) enables stable cast film extrusion with minimal die build-up or gels.
- Superior Mechanical Balance: Combines stiffness with flexibility, offering both rigidity for handling and ductility for puncture resistance.
- Regulatory Compliance: Suitable for direct food contact applications (according to applicable regulations – please confirm local requirements).
- Consistent Quality: Produced by SABIC under strict quality control, ensuring batch-to-batch uniformity.
Our SABIC PP 621P is widely used in cast film production for food packaging such as fresh produce bags, snack food wrappers, laminated films, and flow-wrap packaging. It also performs well in multi-layer co-extrusion systems where optical properties and bond strength are critical.

Frequently Asked Questions (FAQ)
-
Q: What is the typical processing temperature range for SABIC PP 621P cast film?
A: For cast film extrusion, typical melt temperatures range from 220°C to 280°C, with recommended die temperatures between 230°C and 260°C. Optimal conditions depend on film thickness and line speed. -
Q: Is SABIC PP 621P suitable for direct food contact?
A: Yes, this grade is generally compliant with food contact regulations such as FDA and EU directives, but we recommend verifying with your local authority or requesting a compliance letter from our technical team. -
Q: Can this material be used in multi-layer co-extrusion?
A: Absolutely. SABIC PP 621P has good compatibility with other polyolefins (LDPE, LLDPE, etc.) and can be used as the sealant or core layer in multi-layer structures. -
Q: What is the shelf life of these pellets?
A: When stored in a cool, dry place away from direct sunlight, the pellets can be used for up to 2 years without significant property degradation. -
Q: Do you provide free samples for testing?
A: Yes, we offer free samples (around 5 kg) for qualified buyers. Please contact our sales team to arrange shipment. -
Q: What is the minimum order quantity (MOQ)?
A: Our standard MOQ is 1 metric ton (40 bags of 25 kg). For trial orders, we may accommodate smaller quantities upon request. -
Q: How does SABIC PP 621P compare to PP homopolymer for clarity?
A: Random copolymer PP like 621P offers significantly lower haze and higher gloss than homopolymer PP, making it the preferred choice for optical applications. -
Q: Can this resin be recycled?
A: Yes, polypropylene is widely recyclable (resin code 5). Post-industrial scrap can be reprocessed, but please consult with your recycler regarding compatibility with food-contact recycling streams.
