Gail HDPE G-Lene B53A003U
Gail HDPE G-Lene B53A003U is a natural-colour, UV-stabilized high density polyethylene (HDPE) resin from GAIL (India) Limited, developed for blow moulding of small-size cylindrical or near-cylindrical containers up to 5 litres. It is positioned for packaging where converters need a dependable balance of toughness and processability—especially for coloured packs and products that may see light or outdoor exposure.
GAIL describes B53A003U as being produced via G-Lene swing-plant technology (solution and gas-phase routes) and is engineered to deliver an optimum combination of toughness and ease of processing for small bottle production. The grade is also described as an ethylene–hexene copolymer, which is commonly associated with improved toughness and environmental stress crack resistance (ESCR) compared with many homopolymer HDPEs—useful for bottles that face handling abuse, cap stress, and contact with surfactants or oils.
For standards-driven procurement, the GAIL TDS states that B53A003U conforms to the natural-resin designation IS 7328-3B-PB-FXTA under IS 7328:2020 (polyethylene raw material used in moulding and extrusion). This conformity statement should be treated as the primary compliance anchor for the page.
Technical insights
B53A003U is typically shortlisted by blow moulders using a set of properties that correlate with parison stability, cycle consistency, bottle stiffness, and resistance to cracking in real packaging environments.
Melt Flow Index (MFI): Typical MFI (I2, 190°C/2.16 kg) is 0.38 g/10 min. In blow moulding, lower MFI generally indicates higher melt strength, which can support parison control and help maintain wall distribution—important for small containers where appearance and top-load matter.
Density: Market references commonly cite density around 0.953 g/cm³ for this grade. In HDPE blow moulding, higher density typically contributes to better stiffness and top-load performance, supporting bottles that must stack, ship, and resist paneling.
Tensile strength and elongation: Your provided inputs cite tensile strength at yield 270 kg/cm² and elongation at break 700% (treat non-GAIL sources as secondary; keep the page anchored to the GAIL TDS for authoritative claims). This type of profile supports bottles that need to survive drops and squeezes without cracking.
Flexural modulus: Flexural modulus is often used as a quick predictor of bottle rigidity and “feel.” Your inputs cite 10000 kg/cm², which aligns with a stiff packaging grade suitable for small bottles.
Impact strength: Notched Izod impact strength is frequently used to compare toughness across blow grades. Your inputs cite 92 J/m, supporting the positioning for tough, small containers.
ESCR: ESCR (ASTM D1693B, 100% Igepal, F50) is a key packaging metric for detergents, toiletries, and chemical bottles. Your inputs cite 80 hours, indicating a grade positioned for better stress-crack resistance than many general-purpose HDPEs.
UV stabilization: B53A003U is positioned as UV-stabilized, which helps slow degradation (embrittlement and loss of strength) when bottles are exposed to sunlight during storage, transport, or outdoor use.
Applications
Edible oil and ghee bottles (up to 5 L)
B53A003U is recommended for small blow-moulded containers used for edible oils and ghee where converters need stiffness, good appearance, and toughness for distribution handling. UV stabilization can be useful when packs are stored or displayed in light-exposed environments.
Toiletries and cosmetics packaging
For shampoos, lotions, personal-care liquids, and cosmetic containers, this grade’s positioning emphasizes toughness and ESCR—important where surfactants, fragrances, and repeated cap/handling stresses can trigger cracking in weaker materials.
Lubricant and automotive-fluid bottles
B53A003U is suitable for lube-oil bottles and related small containers where stiffness, impact resistance, and resistance to stress cracking help maintain pack integrity through transport and workshop handling.
Industrial chemical bottles (small-size)
For industrial-chemical packaging under 5 L, processors commonly prioritize ESCR and impact performance. The grade’s copolymer positioning and UV stabilization support durability in tougher storage and handling conditions.
Comparable alternatives
Comparable GAIL blow-moulding grades include B52A003/B52A003N and B53A003 (non-UV variants are often positioned for similar small-container applications). Based on your inputs, B53A003U’s key differentiator is UV stabilization, making it better suited for coloured packs and products that may be exposed to sunlight.
Direct equivalence should not be assumed unless you match manufacturer technical sheets and validate on your blow moulding line. For substitution screening, compare MFI (0.38 class), density (~0.953 class), ESCR, impact, and stiffness, then confirm parison behavior, cycle time, and bottle drop performance via trials.
Common search variants
