Blow Molding Equipment Manufacturers

Extrusion Blow Molding (EBM)

Materials: HDPE, LDPE, PP

Use Cases:

  • Milk jugs
  • Juice bottles
  • Yogurt drink bottles (opaque)

Capabilities:

  • Produces hollow containers with handle options (e.g., gallon jugs)
  • Can mold complex shapes
  • Single- or multi-layer structures (e.g., barrier layers for light or oxygen)

Injection Blow Molding (IBM)

Materials: PP, PET (less common for large bottles)

Use Cases:

  • Small beverage bottles (e.g., probiotic shots)
  • Flavor concentrates

Capabilities:

  • High precision and uniform wall thickness
  • Ideal for small-volume, high-clarity bottles

Stretch Blow Molding (SBM)

Pet Blow Molding Machine Suppliers

One-Step SBM (Injection + Stretch + Blow)

  • Used for: Custom or low-volume PET bottle production
  • Applications: Specialty juices, dairy, smoothies

Two-Step SBM (Preform + Blow)

  • Used for: High-volume production (e.g., water, soda bottles)
  • Materials: Primarily PET
  • Use Cases:
    • Carbonated beverage bottles (CSD)
    • Bottled water (500 mL to 2 L)
    • Juices, teas, energy drinks
  • Capabilities:
    • Excellent clarity and gloss
    • High pressure resistance (carbonation)
    • Lightweighting (thin walls, optimized shapes)
    • Fast cycle times for mass production

PET Machines and Capabilities

Why PET?

PET (Polyethylene Terephthalate) is the most widely used plastic for beverage packaging due to its clarity, strength, and ability to form lightweight containers suitable for carbonated and still drinks.

Machine Capabilities:

  • Preform Injection Machines: Produce PET preforms in a wide range of neck sizes and weights
  • Stretch Blow Molding Machines:
    • High-speed, high-volume production (up to 50,000 bottles/hour)
    • Automated changeover for different bottle formats
    • Integrated systems for hot-fill and aseptic applications
    • Compact or modular setups for scalable capacity
  • Mold Customization: Supports ergonomic, branded shapes
  • Inline Inspection Systems: Ensures quality and consistency during production

Applications:

  • Water, soda, energy drinks, juices
  • Sports drinks, flavored teas
  • Shelf-stable dairy and protein drinks

Bottle Sizes & Shapes

  • Sizes: 50 mL – 5 L+
  • Shapes: 50 mL – 5 L+
    • Round (water, soda)
    • Square/rectangular (juice, smoothies)
    • Ergonomic/grip designs (sports drinks, milk)
    • Wide mouth (yogurt, protein drinks)

Additional Features

  • Barrier Layers: To block oxygen, UV, or CO₂ loss (e.g., multilayer PET or EBM bottles)
  • Hot-Fill Capability: PET bottles modified for hot juices or teas (up to ~85–95°C)
  • Aseptic Bottles: Sterile containers for shelf-stable beverages
  • Tamper-Evident Closures: Integrated during post-processing
  • Customization: Color, embossing, labeling surfaces, neck finishes
