OPaL HDPE Opalene F5010

OPaL HDPE Opalene F5010 (HDPE F5010) is a natural‑colored high‑density polyethylene (HDPE) film‑extrusion grade manufactured by ONGC Petro additions Limited (OPaL) under the Opalene (Opalene HD) product line. Produced using Mitsui CX slurry polymerization technology, F5010 is positioned for food‑contact and general‑purpose flexible packaging films, including liners and wrapping applications where processors want a clean balance of processing stability, stiffness, and clarity.

As an HDPE film grade, F5010 is typically chosen when converters need films that feel crisper and stiffer than LLDPE, with strong barrier performance against moisture and good temperature resistance for everyday packaging use. The grade is widely referenced for packaging formats such as liners and wrapping films, where consistent extrusion, neat appearance, and dependable mechanical performance matter for both brand owners and industrial buyers.

A key differentiator for F5010 is its explicit food‑contact compliance positioning. OPaL’s food‑contact declaration states that the grade meets IS 10146:1982 for safe use in contact with foodstuffs, pharmaceuticals, and drinking water, and that the grade and its additives conform to IS 10141:1982 (positive list of constituents). The same declaration also references compliance alignment with major global food‑contact frameworks (including FDA and EC‑type requirements), which is especially valuable for regulated packaging and pharma‑liner projects.

Technical insights

Converters and packaging buyers typically evaluate F5010 using a small set of film‑relevant properties that predict output stability, film feel, and end‑use durability:

• Melt Flow Index (190°C/2.16 kg): 1.0 g/10 min indicates a film‑friendly flow level that supports stable extrusion through film dies and consistent gauge control. It’s a practical balance between processability and mechanical performance.
• Density (23°C): 0.950 g/cm³ is characteristic of HDPE and is strongly linked to stiffness, tensile strength, and moisture‑barrier performance versus lower‑density polyethylenes.
• Tensile strength at yield: 21 MPa and tensile strength at break: >30 MPa indicate good load‑bearing capability and resistance to tearing under stress, supporting packaging integrity during filling, handling, and transport.
• Elongation at break: >500% signals useful ductility, helping films tolerate stretching and handling without brittle failure.
• Notched Izod impact (23°C): >250 J/m supports toughness, reducing cracking risk in real‑world packaging abuse.
• Flexural modulus: 900 MPa aligns with the “crisp” HDPE film feel and supports better bag/liner body and shape retention.
• Hardness: 62 Shore D indicates a robust surface and contributes to durability in liner and wrapping use.
• ESCR (ASTM D1693B, F50, 10% Igepal): 30 hours provides a stress‑crack resistance reference point relevant for certain packaged goods and handling conditions.
• Vicat softening point: 123°C indicates temperature resistance that can be beneficial for packaging exposed to warmer environments.

Note: Values are stated as typical values (not specification limits), and mechanical properties are reported on compression‑moulded specimens. A commonly referenced processing temperature window for this grade is 180–220°C.

Applications

Food packaging films

F5010 is positioned as a food‑packaging HDPE film grade for converters producing films that require a clean appearance, good stiffness, and reliable performance in contact with food. It is relevant for packaging buyers who need documented compliance language (IS 10146/IS 10141 and FDA/EC‑type statements) to support internal QA and customer approvals.

General‑purpose packaging and wrapping

For general‑purpose packaging films and wrapping, F5010 is used when processors want an HDPE film that runs consistently and delivers a crisp, strong film structure. This makes it suitable for everyday packaging formats where strength, neatness, and stable extrusion matter more than extreme stretch.

Liners (industrial and consumer packaging)

F5010 is commonly referenced for liner film applications, where stiffness and durability help with easy handling and better bag/liner “body.” The HDPE density profile supports moisture‑barrier performance, which is often a key requirement for liners used in storage and transport.

Film structures requiring higher stiffness than LLDPE

Where LLDPE films may feel too soft or lack the desired stiffness, F5010 can be selected to deliver a more rigid film structure and improved water‑vapour barrier characteristics typical of HDPE. This is especially relevant for packaging lines targeting better machinability and pack presentation.

Comparable alternatives

• Other HDPE film grades (F‑series / market equivalents): Comparable HDPE film‑extrusion grades exist in India with similar “packaging film” positioning. However, exact equivalence should only be claimed after matching manufacturer TDS values (MFI, density, tensile, impact, Vicat, ESCR) and confirming food‑contact declarations.
• LLDPE film grades (material comparison): LLDPE is often chosen for higher toughness and stretch, but it typically delivers lower stiffness than HDPE. F5010 is positioned for converters who want stiffer, crisper films and stronger moisture‑barrier behavior associated with HDPE.
• HDPE grades without explicit food‑contact declarations: Some listings may show similar processing properties, but F5010’s advantage is the clear, documented IS 10146/IS 10141 and FDA/EC‑type compliance statements, which can simplify approvals for food and pharma‑adjacent packaging.

Practical buying note: if your end‑use is regulated (food/pharma), prioritize grades with explicit declarations and align the final film performance to your structure, thickness, and processing conditions.
