OPaL HDPE Opalene F52H04

OPaL HDPE Opalene F52H04 (HDPE F52H04) is a natural‑colored high‑density polyethylene (HDPE) film‑extrusion grade manufactured by ONGC Petro additions Limited (OPaL) under the Opalene (Opalene HD) portfolio. Produced using Mitsui CX slurry polymerization technology, this grade is engineered for high‑speed blown‑film extrusion where converters need excellent mechanical strength, high stiffness, and strong processability on bag‑making lines.

F52H04 is positioned as a carry‑bag / garment‑packaging / shopping‑bag HDPE film grade and is commonly selected for tissue‑like films and everyday bag applications that must feel crisp, hold shape, and resist draw‑down during conversion. As a low‑branching polyolefin, HDPE typically delivers higher tensile strength and modulus and a better water‑vapour barrier than many LLDPE alternatives—making it a practical choice for packaging formats where stiffness and barrier performance are prioritized.

A major trust signal for regulated packaging is OPaL’s explicit compliance positioning. The technical and food‑contact documents state that F52H04 meets IS 10146:1982 for safe use in contact with foodstuffs, pharmaceuticals, and drinking water, and that the grade and additives conform to IS 10141:1982 (positive list of constituents). The official food‑contact declaration also references alignment with major international food‑contact frameworks (including FDA and EU‑type requirements), supporting buyers who need documentation for audits, approvals, and customer QA.

Technical insights

F52H04’s typical properties are evaluated by film processors to predict extrusion stability, bubble strength, bag stiffness, and long‑term durability:

• Melt Flow Index (190°C/2.16 kg): 0.04 g/10 min is an ultra‑low flow level that typically correlates with high melt strength and high stiffness in the finished film. It can be ideal for strong carry‑bag films, but may require appropriate extruder torque and stable processing control.
• Density (23°C): 0.952 g/cm³ supports higher rigidity and modulus, contributing to the crisp feel and shape retention expected in shopping and garment bags.
• Tensile strength at yield: 27 MPa indicates strong resistance to deformation under load—important for carry bags that must hold weight without excessive stretching.
• Elongation at break: >500% signals useful ductility, helping films tolerate handling and conversion stresses without brittle failure.
• ESCR (ASTM D1693B, F50, 10% Igepal): >500 hours is a major durability indicator, supporting performance in humid or chemically aggressive environments and reducing stress‑crack risk over time.
• Hardness: 64 Shore D aligns with a more rigid HDPE film feel and improved resistance to surface damage in handling.
• Vicat softening point: 124°C indicates temperature resistance that can be helpful for storage, transport, and use in warmer conditions.

Note: These are typical values (not specification limits), and mechanical properties are reported on compression‑moulded type‑IV specimens. A commonly referenced processing range for HDPE film grades of this type is 180–220°C, with final settings dependent on line configuration and output targets.

Applications

Carry bags and shopping/counter bags

F52H04 is designed for carry‑bag and shopping‑bag film extrusion, where stiffness and draw resistance are critical for bag performance. The high‑stiffness HDPE profile helps bags hold shape, feel crisp, and carry loads with reduced sagging—making it suitable for retail, grocery, and merchandise packaging.

Garment packaging and tissue‑like films

For garment packaging and tissue‑like films, converters often prioritize consistent processing at high speed and a neat, premium film feel. F52H04’s low MFI and high stiffness positioning supports stable blown‑film production and strong finished‑film structure for everyday packaging use.

Garbage/disposal waste bags

In garbage and disposal waste bags, film toughness and resistance to cracking matter in real‑world handling. F52H04’s ESCR positioning helps improve durability, while the stiffness profile supports bag integrity and handling during filling and disposal.

General bag‑making lines needing high‑speed output

F52H04 is a fit for converters running high‑speed blown‑film extrusion and bag conversion, where output consistency, mechanical strength, and stiffness are key. It is commonly evaluated for projects that require documented compliance statements alongside performance.

Comparable alternatives

• OPaL HDPE Opalene F5010 (HDPE film grade): A packaging‑film grade with a much higher MFI (1.0 g/10 min) than F52H04. That difference typically changes processing behavior and finished‑film stiffness; F5010 may be easier flowing, while F52H04 is positioned for high stiffness and high‑speed bag film.
• Other OPaL/market HDPE bag film grades (e.g., F55H04 and similar): Comparable HDPE film grades exist for carry bags and packaging films, but direct grade equivalence should only be claimed after matching manufacturer TDS values (MFI, density, ESCR, tensile, Vicat) and verifying food‑contact declarations.
• LLDPE bag grades (material comparison): LLDPE is often chosen for higher stretch and puncture toughness, but it generally delivers lower stiffness than HDPE. F52H04 is positioned for converters who want crisper, stiffer bags and HDPE‑type barrier performance.

Practical buying note: for bag applications, the biggest “selection lever” is often MFI + density, because it drives both processing behavior and film stiffness. Match these to your target thickness, load rating, and line capability.
