Shanghai Wenqin Plastics Co., Ltd., established in 2020 and operating from our facility in Shanghai, specializes in providing high-performance polymer materials to global markets. We are proud to introduce our TR-144 HDPE Film Grade Resin with Controlled Melt Flow Index, a product engineered to deliver reliability and consistency for film manufacturers worldwide. Our commitment to quality management systems, including ISO9001 and ISO14000, underpins every batch we produce, ensuring you receive a material that meets stringent specifications for your critical film applications.
The TR-144 resin is specifically designed for film extrusion processes. Its primary value lies in its controlled and consistent Melt Flow Index (MFI). MFI is a crucial parameter affecting processability and final film properties such as tensile strength, tear resistance, and drawability. By offering a resin with a tightly controlled MFI, TR-144 helps manufacturers achieve:
- Stable Processing: Reduced fluctuations in extrusion conditions, leading to fewer production interruptions and higher output efficiency.
- Uniform Film Quality: Consistent film gauge (thickness), strength, and surface characteristics across production runs.
- Predictable Performance: Enables accurate planning and optimization of production parameters like temperature and screw speed.
This resin is suitable for a wide range of film types, including but not limited to:
- Shopping bags and carry sacks
- Food packaging films
- Agricultural films (e.g., greenhouse films, silage wraps)
- Liners and protective films
Technical Specifications & Advantages:
The core advantage of TR-144 is its engineered molecular structure that yields a stable MFI. This stability translates into several tangible benefits for the end-user:
| Feature / Parameter | Benefit to Film Producer |
|---|---|
| Controlled Melt Flow Index | Ensures consistent melt viscosity, leading to uniform film extrusion and reduced gauge variation. |
| High-Density Polyethylene Base | Provides excellent stiffness, moisture barrier properties, and chemical resistance for the final film. |
| Film Grade Optimization | Molecular weight distribution tailored for high draw-down rates and good bubble stability in blown film processes. |
| Consistent Batch-to-Batch Quality | Minimizes the need for process re-adjustments with new material batches, saving time and reducing waste. |
Furthermore, the resin offers good compatibility with common additives (e.g., pigments, UV stabilizers, slip agents), allowing for customization to meet specific film requirements. Its processing window is designed to be forgiving, aiding in stable operation even under varying ambient conditions.

Frequently Asked Questions (FAQ):
-
Q: What is the typical Melt Flow Index range for the TR-144 resin?
A: The MFI is controlled within a specific, narrow range to ensure consistency. The exact value is available upon request and can be tailored to suit certain processing requirements. -
Q: Is this resin suitable for both blown film and cast film processes?
A: The TR-144 grade is primarily optimized for blown film extrusion, where controlled MFI is critical for bubble stability. Its suitability for cast film processes can be evaluated based on specific machine parameters. -
Q: Does the resin come with any additives or is it a pure base polymer?
A: TR-144 is offered as a base film-grade HDPE resin with controlled MFI. It is designed for excellent additive acceptance, allowing customers to compound it with their preferred masterbatches or additives. -
Q: What packaging options are available?
A: Standard packaging is in bags. Bulk container options may also be available depending on order volume and destination. Please inquire for details. -
Q: Can you provide technical data sheets and processing guidelines?
A: Yes, comprehensive technical data sheets and recommended processing guidelines are provided with the product or upon request. -
Q: How does batch-to-batch consistency benefit my production?
A: Consistent MFI means you can maintain your extrusion settings (temperature, speed) without frequent adjustments. This reduces start-up waste, improves overall equipment efficiency (OEE), and ensures your film quality meets specifications consistently. -
Q: What are the main applications for films made from this resin?
A: Typical applications include various packaging films (retail bags, food packaging), agricultural films, and industrial liner films. The good balance of properties makes it versatile. -
Q: Do you offer sample quantities for testing?
A: Sample quantities are often available for customer evaluation and trial runs. Please contact our sales team to arrange samples.
