HMEL HDPE Polysure F0146D

HMEL HDPE Polysure F0146D is a 1-hexene co-monomer based high density polyethylene developed by HPCL-Mittal Energy Limited under its Polysure HDPE portfolio for blown film extrusion. Produced using Advanced Dual Loop Slurry MarTECH technology, this grade is designed for film converters looking for excellent processability, good bubble stability, strong mechanical performance, and high filler loading capability in cost-sensitive packaging applications.

HPCL-Mittal Energy Limited is one of India’s leading petrochemical producers supplying polyethylene grades for film, pipe, blow moulding, and packaging applications. Within the HMEL HDPE film portfolio, F0146D is positioned as a general purpose blown film grade suited for everyday packaging film production where processors need a practical balance of film strength, stable bubble behavior, and formulation flexibility. It is especially relevant for manufacturers producing T-shirt bags, shopping bags, multi-wall liners, trash bags, industrial liners, and multilayer films for high-volume commercial use.

Technical Specifications and Deep Technical Insights

HMEL HDPE Polysure F0146D has a melt flow index of 0.18 g/10 min and a density of 0.946 g/cc, making it suitable for blown film extrusion where melt strength, film toughness, and process consistency are important. This property balance supports stable film formation and helps converters maintain reliable output across a wide range of packaging film applications.

In film testing conditions based on 25 micron film, BUR 4, and 1 mm die gap, the grade shows tensile strength at yield of 24 MPa in MD and 26 MPa in TD, tensile strength at break of 50 MPa in MD and 30 MPa in TD, and elongation at break of 480% in MD and 640% in TD. It also delivers Elmendorf tear strength of 0.8 g per micron in MD and 10.8 g per micron in TD, along with dart impact strength of 3.6 g per micron. These values indicate a film grade that offers a useful combination of strength, flexibility, and impact resistance for bag and liner production.

One of the most important commercial advantages of F0146D is its good bubble stability. For blown film processors, bubble stability directly affects line control, gauge consistency, and production efficiency. A stable bubble reduces processing interruptions and helps maintain smoother operations, especially in high-volume bag and liner manufacturing.

Another major strength is its high filler loading characteristic, which is highly relevant for converters aiming to optimize formulation cost without sacrificing practical processing behavior. Combined with excellent processability, this makes F0146D a strong option for manufacturers focused on economical film production for commodity and industrial packaging segments.

Recommended barrel temperature is 180 to 220°C. For storage and handling, the material should be kept in a dry and dust-free environment below 50°C and protected from direct sunlight and heat exposure to preserve resin quality before processing.

Applications

T-Shirt Bags and Shopping Bags

HMEL HDPE Polysure F0146D is highly suitable for T-shirt bags, shopping bags, and kirana bags where processors need a blown film grade that can run efficiently and deliver dependable film strength. Its bubble stability and mechanical performance make it a practical choice for high-volume retail bag production where consistency and cost control both matter.

General Purpose Packaging Films

For general purpose packaging film applications, F0146D offers a balanced combination of processability, toughness, and formulation flexibility. This makes it useful for converters producing everyday HDPE packaging films for commercial, industrial, and distribution use where stable output and reliable film properties are essential.

Multi-Wall Liners and Industrial Liners

The grade is well suited for multi-wall liners and industrial liners because these applications require film strength, durability, and dependable extrusion behavior. F0146D supports the production of liners used in bulk packaging, industrial sacks, and protective packaging systems where mechanical integrity is important.

Trash Bags

Trash bag manufacturing benefits from the grade’s good processability, impact resistance, and elongation performance. These properties help converters produce films that can handle routine loading and handling conditions while maintaining manufacturing efficiency on blown film lines.

Multilayer Films

F0146D can also be used in multilayer film structures where processors need a general purpose HDPE component with stable processing and good mechanical contribution. Its filler loading capability and blown film performance make it relevant for cost-sensitive multilayer packaging applications.

Comparable Alternatives

Within the HMEL film portfolio, F0153S is positioned more toward carry bags and co-extruded film applications with a slightly higher density profile, while F0050D is aligned with HM film and heavy duty film applications using a different flow reference. In comparison, F0146D sits as a versatile general purpose blown film grade for T-shirt bags, shopping bags, liners, and trash bags where balanced processability and mechanical performance are the main requirements.

Against comparable Indian grades such as GAIL 18H55, OPaL F18, IOCL 18H55, and similar Reliance HDPE film grades, F0146D competes in the general purpose blown film category with a strong value proposition around bubble stability, filler loading, and practical bag-making performance. The rationale behind this grade is clear: it is assigned to applications where converters need a dependable HDPE blown film resin that supports economical production without moving into highly specialized heavy-duty film territory.
