Bottle Conveying Systems

Purpose: Transport blow-molded bottles from the molding machine to baggers or packers.

Types:

  • Air conveyors (for lightweight PET bottles)
  • Belt conveyors (HDPE, PP bottles)
  • Modular chain conveyors
  • Vacuum-assisted conveyors (for precise alignment)

Features:

  • Bottle spacing control
  • Gentle handling to prevent deformation
  • Bottle orientation units (upright or neck-first)

Bottle Bagging Machines

These systems automatically bag bottles for bulk shipping or storage.

Common Bagging Machine Types:

Type Suitable For Bottle Types
Automatic baggers High-speed PET or HDPE lines Beverage, dairy, personal care
High-volume operations
Semi-automatic baggers Mid-volume or short runs Detergent, chemical, household
Neck-down/neck-up bagging Bottles oriented for bag entry All industries

Features:

  • Film roll unwinding and cutting
  • Heat sealing or twist tie
  • Bottle counting (batch size control)
  • Neck protection collars or inserts
  • Air evacuation for compact bags

Bottle Collating Systems

Used for organizing bottles into rows or groups before bagging or boxing.

Collating Type Description
Single-lane collator Aligns bottles for linear baggers
Multi-lane collator Used for faster lines, multi-row packaging
Puck or tray feeders For unstable or squeezable bottles

Bottle Boxing / Cartoning Machines

Some operations skip bagging and go straight to box or tray packaging.

Machine Type Suitable Use Case
Case packers For PET/HDPE bottles in trays or cartons
Tray + shrink wrapper Bundle bottle sets (e.g., 6-packs)
Robotic case packers Flexible format changes, orientation-sensitive

Palletizing & Stretch Wrapping

After bagging/boxing, bottles are typically palletized for storage or shipment.

Equipment Description
Robotic palletizers High-speed, programmable stacking
Layer-forming palletizers Build stable bottle layers with slip sheets
Stretch wrappers Secure loads with film for transport

Packaging Configuration Examples by Industry

Some operations skip bagging and go straight to box or tray packaging.

Industry Common Packaging Downstream Focus
Beverage (PET) Neck-up bagging or tray + shrink High-speed conveying, orientation
Dairy (HDPE) Bagged in bulk, neck-down Gentle handling, fast bag sealing
Household Cleaning Boxed or bagged bottles Handle protection, chemical-resistant film
Personal Care Tray or case packing Scratch protection, label orientation
Detergents Bagged or palletized bulk Reinforced bags, neck/cap protection

Main Downstream Features & Equipment

  • Vision systems: Detect missing, misaligned, or defective bottles
  • Leak testers: Inline air pressure tests before bagging
  • Neck protectors: Cardboard/plastic inserts to protect threads or caps
  • Dust control systems: For cleanroom environments (personal care, dairy)
