Lubricant Packaging Blow Molding Solutions
Plastic Bottles for Lubricants
Lubricant bottles require chemical resistance, rigid construction, precise neck finishes, and in many cases, integrated handles. Blow molding machines for these bottles must be optimized for durability, cleanliness, and industrial-grade throughput.
Best-Suited Blow Molding Process: Extrusion Blow Molding (EBM)
| Feature | Description |
|---|---|
| Most common process | EBM is ideal due to its ability to form large, thick-walled bottles, handle integration, and chemical-resistant resins |
| Machine Types | Continuous extrusion, shuttle-type, or accumulator-head EBM machines |
| Mold Cavities | Typically 1 to 8+ cavities, depending on bottle size |
| Output Speed | ~300–1,500 bottles/hour per cavity, depending on size & resin |
Materials Used for Lubricant Bottles
| Plastic Type | Key Properties | Notes |
|---|---|---|
| HDPE | High chemical resistance, impact strength | Most common resin used for oil & lubricant bottles |
| PP | Better heat resistance, good for caps and small bottles | Used for smaller containers or caps/inserts |
| Multilayer (e.g. HDPE/EVOH/HDPE) | Barrier properties for oxygen-sensitive products | Optional for advanced packaging |
| Post-consumer recycled HDPE (PCR) | Sustainability | Used in eco-conscious lubricant brands |
Bottle Sizes and Shapes Typically Produced
| Bottle Size Range | Common Use Cases | Machine Adaptation |
|---|---|---|
| 250 mL – 1 L | Motorcycle oil, brake fluid, additives | Multi-cavity EBM or IBM (small volumes) |
| 1 L – 5 L | Standard automotive oil bottles | Shuttle-type EBM machines with in-mold handles |
| 5 L – 20+ L | Industrial bulk lubricant jugs | Accumulator-head EBM machines with large parison control |
Bottle Design Features Supported
| Feature | Supported by | Notes |
|---|---|---|
| In-mold handles | EBM | For 3L–20L bottles to improve pouring |
| Graduated markings | Mold design | Optional for volume tracking |
| Wide mouth or narrow necks | EBM & IBM | For pouring or dispensing control |
| Threaded necks | All processes | Compatible with screw caps, induction seals |
| Stacking features | Mold design | For warehouse/shipping optimization |
| Custom logos / embossing | Mold tooling | Branding directly on the bottle |
Specialized Capabilities
| Capability | Importance for Lubricants | Machine Type |
|---|---|---|
| Fluorination (in-line or offline) | Prevents paneling and chemical permeation | EBM bottles only |
| Co-extrusion (Multilayer) | Enhances barrier for oxygen-sensitive oils | EBM multilayer heads |
| Heavy-wall molding | Required for thick oil bottles | EBM, Accumulator-head |
| Neck calibration | Ensures cap fit, especially for tamper-evident | IBM or EBM (with calibration) |
| Automatic deflashing | Clean finish after molding | Shuttle and accumulator EBM |
| Regrind integration | Sustainable production | Modern EBM systems |
Specialized Capabilities
| Machine Type / Configuration | Bottle Size Range |
|---|---|
| Shuttle EBM Machines | 250 mL – 5 L |
| Accumulator Head EBM | 5 – 20+ L |
| IBM (small bottles) | 50 – 500 mL |
| Co-extrusion EBM | Up to 6 layers |
