HMEL HDPE Polysure F0050D

HMEL HDPE Polysure F0050D is a 1-hexene co-monomer based bimodal high molecular weight high density polyethylene developed by HPCL-Mittal Energy Limited under the Polysure HDPE range for blown film extrusion. Produced using Advanced Dual Loop Slurry MarTECH technology, this HM film grade is designed for converters who need excellent processability, good bubble stability, strong film toughness, and dependable durability in heavy duty packaging applications.

HPCL-Mittal Energy Limited is one of India’s major petrochemical manufacturers supplying polyethylene grades for film, pipe, blow moulding, and industrial packaging applications. Within the HMEL HDPE film portfolio, F0050D is positioned as a heavy duty HM film grade for processors looking for stronger film performance than standard general purpose HDPE film grades. Its bimodal structure and high molecular weight profile make it especially relevant for industrial liners, merchandise bags, trash bags, general purpose shopping bags, grocery carry bags, and selected food packaging film applications.

Technical Specifications and Deep Technical Insights

HMEL HDPE Polysure F0050D has a melt flow index of 0.05 g/10 min at 190°C/2.16 kg, a melt flow index of 8 g/10 min at 190°C/21.6 kg, and a density of 0.950 g/cc. This property profile reflects a bimodal HM-HDPE film resin built for blown film extrusion where melt strength, toughness, and heavy duty film performance are important.

Under film testing conditions based on 20 micron film, BUR 4, and 1 mm die gap, the grade shows tensile strength at yield of 30 MPa in MD and 32 MPa in TD, tensile strength at break of 60 MPa in MD and 55 MPa in TD, and elongation at break of 370% in MD and 650% in TD. It also delivers Elmendorf tear strength of 0.8 g per micron in MD and 20 g per micron in TD, along with dart impact strength of 8.7 g per micron. These values indicate a film grade with strong toughness, high impact resistance, and robust end-use performance for demanding bag and liner applications.

A major technical advantage of F0050D is its bimodal molecular weight distribution, which helps create a useful balance between processability and mechanical strength. For film converters, this means the resin can support stable extrusion and bubble control while also delivering the toughness and durability expected in heavy duty HM film structures.

The grade is also valued for good bubble stability, which is critical in blown film processing because it affects gauge consistency, line control, and production efficiency. Combined with excellent processability, F0050D helps processors run heavy duty film applications with better operational stability and reduced chances of disruption during production.

Typical barrel temperature for HDPE blown film processing is 180 to 220°C. For storage and handling, the material should be kept in a dry, dust-free environment below 50°C and protected from direct sunlight and heat exposure before use.

Applications

Heavy Duty Films

HMEL HDPE Polysure F0050D is highly suitable for heavy duty film production where converters need stronger mechanical performance, better toughness, and improved durability than standard commodity film grades. Its bimodal HM-HDPE profile makes it a strong option for demanding packaging applications that require dependable film integrity during handling and use.

Industrial Liners

For industrial liner applications, F0050D offers the toughness, impact resistance, and blown film stability required for bulk packaging and industrial protection. These properties make it relevant for liner structures used in sacks, industrial packaging systems, and protective film applications where durability is a key requirement.

Merchandise Bags and Trash Bags

The grade performs well in merchandise bags and trash bags where film toughness and puncture resistance are important. Its strong mechanical profile helps converters produce bags that can tolerate heavier loading and more demanding handling conditions while maintaining efficient processing on blown film lines.

Shopping Bags and Grocery Carry Bags

F0050D is also suitable for general purpose shopping bags and grocery carry bags where manufacturers want a tougher HDPE film resin with stable bubble behavior. This makes it useful for bag producers serving retail and commercial packaging segments that need stronger film performance.

Food Packaging Films

In selected food packaging film applications, the grade offers a combination of processability and mechanical reliability that can support practical packaging performance. It is particularly relevant where converters need an HM film grade with durability and stable extrusion behavior for packaging structures.

Comparable Alternatives

Within the HMEL film portfolio, F0146D is positioned as a more general purpose blown film grade for T-shirt bags, shopping bags, and liners, while F0153S is more aligned with carry bags and co-extruded film applications. In comparison, F0050D is the stronger heavy duty HM film option for processors who need higher toughness, better durability, and a more robust mechanical profile.

Against comparable Indian HM film grades such as GAIL H20H55, OPaL F52H04, IOCL H20H55, and similar Reliance HM-HDPE film grades, F0050D competes as a heavy duty blown film resin with a clear focus on toughness, bubble stability, and demanding liner or bag applications. The rationale behind this grade is straightforward: it is assigned where converters need a bimodal HM film resin that goes beyond standard general purpose film performance and supports more demanding end-use conditions.
