Gail HDPE G Lex W52A009

Gail HDPE G‑Lex W52A009 is a high‑density polyethylene (HDPE) grade from GAIL (India) Limited developed for tape/raffia (stretched tape) extrusion and related woven applications. GAIL positions W52A009/W52A009N as “High Density Polyethylene for Tape/Monofilament Extrusion,” widely used for medium‑tenacity stretched tape in woven sacks (including flour packaging and industrial packaging) and tarpaulin, combining excellent processability with good elongation.

In practical terms, this grade is chosen when processors need an HDPE that runs smoothly on tape lines and supports orientation and stretching without excessive tape breaks. The objective is a tape that is strong enough for handling, filling, stacking, and transport, while still retaining sufficient extensibility for weaving and stitching operations.

W52A009 can also be used in medium‑tenacity monofilament products such as fishing nets, but its core fit is tape/raffia and woven‑sack performance.

The datasheet states conformity to IS 7328‑3B‑TB‑FXDA of IS 7328:2020 (natural resin designation) for tape and related products. The grade is supplied in natural‑colour pellets, typically packed in 25 kg woven sacks.

Technical insights

• Melt Flow Index (I2, 190°C/2.16 kg): 0.9 g/10 min (typical). A medium‑flow MFI helps tape lines maintain stable output and draw, supporting consistent tape thickness and orientation behavior.
• Density (23°C): 0.952 g/cm³ (typical). This HDPE density level supports stiffness and strength needed for woven sacks and tarpaulin tapes, while still enabling workable elongation during stretching.
• Tensile strength at yield: 240 kg/cm² (typical). Indicates the tape’s ability to resist permanent deformation under load—important for sack integrity during filling, stacking, and transport.
• Elongation at yield: 11% (typical) and elongation at break: >600% (typical). This strength‑plus‑elongation balance is a key reason processors select W52A009 for stretched tape: it helps reduce brittle breaks during orientation and supports durability in woven structures.
• Flexural modulus: 9500 kg/cm² (typical). Reflects stiffness; contributes to better “body” and handling in woven sacks and tarpaulin fabrics.
• Vicat softening point: 123°C (typical). Suggests good heat resistance for many packaging and outdoor cover use cases, supporting performance in warm storage and transport conditions.
• Processing guidance (barrel temperature): 210–270°C. Typical temperature window provided for tape/monofilament extrusion; final settings depend on extruder, die design, draw ratio, quench conditions, and target tape denier.

Applications

Woven sacks for flour and food‑adjacent packaging: W52A009 is widely used for stretched tape that is woven into sacks where consistent tape quality and reliable weaving performance matter. The grade’s processability and elongation balance support smooth tape orientation and help reduce breaks during downstream conversion.

Industrial packaging woven bags (fertilizer, chemicals, minerals, general bulk handling): For industrial sack producers, the key requirement is a tape that can withstand handling stress at corners and seams during filling and stacking. W52A009 is positioned as a medium‑tenacity raffia grade that delivers a practical strength‑to‑elongation balance for everyday industrial packaging.

Tarpaulin and laminated woven fabrics: In tarpaulin applications, stretched tape must maintain stiffness and strength while tolerating outdoor handling and repeated folding. W52A009 is commonly evaluated for tarpaulin‑oriented woven fabrics where stable tape extrusion and orientation are critical to finished‑fabric performance.

Selective monofilament uses (e.g., medium‑tenacity fishing nets): While primarily a tape grade, W52A009 may be used for certain medium‑tenacity monofilament products where processors want tape‑like orientation characteristics and manageable processing behavior. For monofilament‑first requirements, dedicated monofilament grades should still be compared case‑by‑case.

Comparable alternatives

Within GAIL’s range, W52A009N is the closest comparable option as the UV‑stabilized variant; it is typically considered when outdoor exposure or storage robustness is a priority.

For higher tenacity tape targets, GAIL positions W50A009 as a high‑tenacity stretched tape grade. In many plants, W50A009 is evaluated when the end product demands higher strength performance, but processors should validate orientation behavior, weaving performance, and final fabric properties against the relevant manufacturer datasheets.

For applications that are primarily rope/twine and monofilament‑yarn driven, W52ASR009/W52ASR009N are positioned more directly for monofilament extrusion (ropes, twines, fishing/sporting nets). These are comparable as “nearby” grades in the portfolio, but they are not the same application class as a tape/raffia‑first resin.

As a rule for procurement and process engineering: treat alternatives as comparable grades rather than drop‑in replacements unless MFI, density, tensile/elongation, and (most importantly) tape orientation and conversion performance are matched and proven on your line.
