Project Description
HDPE BL3 is a high-density polyethylene (HDPE) grade commonly used for injection moulding or blow molding applications. It is typically supplied in the form of resin pellets and is known for its excellent process ability and mechanical properties.
HDPE BL3 stands for High-Density Polyethylene, a thermoplastic polymer used in pipes, bottles, plastic lumber, etc.
HDPE means high-Density Polyethylene, a thermoplastic polymer known for its strength, chemical resistance, and durability.
BL means Commonly shorthand for Blow Molding, a manufacturing process used to produce hollow plastic parts like bottles, containers, and drums.
3 means likely denotes the grade or flow property (such as Melt Flow Index range), optimized for specific applications like large containers or bottles.

HDPE BL3 FEATURES
BL3 Technical Details
Ideal for large containers needing durability and rigidity.
HDPE BL3 Applications
Common Applications of BL3:
1)Blow-Molded Containers
- Household chemical bottles (e.g., detergents, cleaners)
- Personal care bottles (e.g., shampoo, lotions)
- Food and beverage containers (non-carbonated)
- Pharmaceutical bottles
2) Industrial Packaging
- Jerry cans
- Drums and barrels (up to ~30L)
- Lubricant and oil containers
3) Automotive and Agrochemical Packaging
- Coolant and windshield washer fluid bottles
- Pesticide and fertilizer containers
4) Toys and Recreational Items
- Molded toys
- Plastic balls or floats
5) Other Uses
- Fuel tanks (in specific formulations)
- Intermediate Bulk Containers (IBCs)
- Construction forms (temporary molds)
Key Properties Making HDPE BL3 Suitable:
- High rigidity and impact strength
- Good ESCR (Environmental Stress Crack Resistance)
- Excellent moldability for extrusion blow molding
- Low permeability to moisture
- Food contact compliance (in certain grades)
HDPE BL3 Formulation
The formulation of BL3 (High-Density Polyethylene for Blow Molding, Grade 3) typically involves:
- Base Polymer Composition
- High-Density Polyethylene Resin
- Polymerized using either Ziegler-Natta or Metallocene catalysts
- Molecular weight distribution: broad to medium, to balance processability and mechanical strength
- Melt flow index (MFI): Typically 0.2 – 1.0 g/10 min (at 190°C/2.16 kg), optimized for blow molding
Typical Additives in HDPE BL3 Formulation
Additive Purpose
Antioxidants Prevent thermal/oxidative degradation during processing (e.g., BHT, phosphites)
UV Stabilizers For outdoor applications, protects against UV aging (e.g., HALS)
Slip Agents Reduce surface friction to improve demolding (e.g., erucamide)
Antiblocking Agents Prevent layers from sticking (e.g., silica)
Processing Aids Improve extrusion behavior (e.g., fluoropolymers, waxes)
Color Masterbatch For pigmentation (carbon black for UV protection, TiO₂ for opacity)
In food-grade or pharmaceutical-grade formulations, only FDA/EU-approved additives are used.
HDPE BL3 Packing
BL3 of PETRO-ACC packing would be:
25 kg polypropylene bags with 1250 kg shrink and wrapped pallets.
Capacities for a different way of shipments would be as below:
20ft & 40ft containers for sea shipment:
20ft FCL: 13 MT/25 kg bags with pallets
40ft FCL: 25 MT/25 kg bags with pallets
The capacity of a Full truck: 25 MT
