Gail HDPE G Lex W52A009N

Gail HDPE G‑Lex W52A009N is a UV‑stabilized high‑density polyethylene (HDPE) grade from GAIL (India) Limited engineered for tape/raffia (stretched tape) extrusion and related woven applications. In GAIL’s datasheet, W52A009/W52A009N is described 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 and strength.

For tape producers and woven‑sack converters, the value of W52A009N is in how it supports stable tape extrusion and orientation while maintaining a practical balance between tape strength (for load‑bearing and handling) and elongation (for stretching, weaving, and stitching without excessive breakage). The “N” variant adds UV stabilization, typically preferred when the finished woven fabric is expected to see outdoor exposure (tarpaulin, open storage, transport) or when added robustness during storage/handling is desired.

GAIL states the grade conforms to IS 7328‑3B‑TB‑FXDA of IS 7328:2020 (natural resin designation) for tape and related products. It is supplied as 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 run smoothly and supports consistent tape thickness and draw during stretching.
• Density (23°C): 0.952 g/cm³ (typical). This density level supports stiffness and strength needed for woven sacks and tarpaulin tapes, while still enabling workable elongation during orientation.
• Tensile strength at yield: 240 kg/cm² (typical). Indicates resistance to permanent deformation under load—important for sack performance during filling, stacking, and transport.
• Elongation at yield: 11% (typical) and elongation at break: >600% (typical). This is a key “conversion‑friendly” signal for stretched tape: it supports orientation and downstream weaving/sewing while reducing brittle tape breaks.
• Flexural modulus: 9500 kg/cm² (typical). Reflects stiffness; contributes to better “body” and handling in woven fabrics and helps maintain structure in sacks and tarpaulin.
• Vicat softening point: 123°C (typical). Suggests good heat resistance for many packaging and outdoor cover use cases.
• Processing guidance (barrel temperature): 210–270°C. Typical temperature window provided for tape/monofilament extrusion; final settings depend on extruder, die, draw ratio, quench conditions, and target tape denier.

Applications

Woven sacks for flour and food‑adjacent packaging: W52A009N is used for stretched tape that is woven into sacks where consistent tape quality, stable weaving, and reliable seam performance are critical. The grade’s strength‑plus‑elongation balance supports orientation and downstream conversion with fewer tape breaks.

Industrial packaging woven bags (bulk handling): For industrial sacks used in chemicals, minerals, and general bulk transport, tape must handle corner and seam stress during filling and stacking. W52A009N is positioned as a medium‑tenacity raffia grade that delivers robust everyday performance while maintaining processability on tape lines.

Tarpaulin and laminated woven fabrics (outdoor use): Tarpaulin fabrics often see sunlight exposure and rough handling. W52A009N’s UV stabilization is a key reason it is evaluated for tarpaulin‑oriented woven structures where outdoor durability and stable tape processing are both required.

Selective monofilament uses (e.g., medium‑tenacity fishing nets): GAIL notes the grade can also be used in medium‑tenacity monofilament products like fishing nets. Where monofilament is the primary requirement, processors should still compare against dedicated monofilament grades and validate performance on the target line.

Comparable alternatives

Within GAIL’s range, W52A009 (non‑UV) is the closest comparable grade; W52A009N is typically preferred when UV/outdoor robustness is required for tarpaulin or exposed storage/transport conditions.

For higher tenacity tape targets, GAIL positions W50A009 as a high‑tenacity stretched tape grade. Buyers often evaluate W50A009 when the end product requires higher strength targets, but orientation behavior, weaving performance, and final fabric properties should be validated before switching.

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

Treat alternatives as comparable options rather than drop‑in equivalents unless MFI, density, tensile/elongation, and (most importantly) tape orientation and conversion performance are matched and proven on your line.
