HDPE BL3
HDPE BL3 – High-Performance Blow Molding Grade Polyethylene
Product overview
HDPE BL3
Product overview
HDPE BL3 is a high-density polyethylene grade specifically engineered for blow molding applications. It offers excellent rigidity, good environmental stress crack resistance (ESCR), and outstanding processability. BL3 is widely used for producing bottles, containers, jerry cans, and industrial packaging requiring high strength, durability, and consistent blow molding performance.
Introduction to HDPE BL3
1
HDPE BL3 is designed for high-quality blow molding applications including bottles, containers, and industrial jerry cans.
2
It provides excellent rigidity, good impact resistance, and reliable melt strength for stable parison formation.
3
BL3 processes smoothly on both single and double-stage blow molding systems, producing high-quality molded products with consistent wall thickness.
Applications
Industrial Containers
Used for small to medium industrial containers and jerry cans due to its rigidity and crack resistance.
Household Packaging
Suitable for home care product packaging such as cleaning liquids and oils.
Food Contact Containers
FDA-approved for food-grade blow molding applications such as milk bottles and food storage containers.
Caps & Closures (Injection–Blow)
Compatible for certain closure applications where HDPE is required.

Production Processes
Blow Molding Process
BL3 granules are melted and extruded to form a parison. Air inflation shapes the parison inside a mold, forming rigid and durable containers.
Cooling, Trimming & QC
Formed containers are cooled, trimmed, and inspected for wall thickness, impact resistance, and surface quality.
