Pharmaceutical Blow Molding Solutions

Capabilities for Pharmaceutical Containers

The pharmaceutical industry demands high standards for packaging sterility, precision, barrier performance, and compliance with strict regulatory guidelines. Pet All Manufacturing offers specialized technologies and equipment to meet these needs.

PET Blow Molding Capabilities (Primarily ISBM)

PET (Polyethylene Terephthalate) is a preferred material in pharma for its clarity, chemical resistance, and processability. PET containers are mainly produced using Injection.

Blow Molding Equipment Manufacturers

Stretch Blow Molding (ISBM).

Key Capabilities:

  • Glass-like clarity for content visibility and inspection.
  • High precision neck finishes for tamper-evident and child-resistant closures.
  • Excellent barrier properties against moisture and gases.
  • Multilayer options with EVOH or SiOx for sensitive contents.
  • One-stage ISBM: Injection + stretch blow in one machine - ideal for sterile or low-volume pharma runs.
  • Two-stage ISBM: High-volume, high-speed production - ideal for oral liquids, diagnostic bottles, and vials.
  • Cleanroom compatible (ISO 7 or ISO 8), including HEPA filters and laminar flow.
  • Serialization, vision inspection, and full automation available.

Common pharma applications: Eye drop bottles, liquid medication bottles, oral syrups, reagent bottles, contact lens solutions.

Pet Blow Molding Machine Suppliers

Injection Blow Molding (IBM)

IBM is widely used in the pharmaceutical sector for small, high-precision containers such as vials and droppers.

Key Capabilities:

  • Superior dimensional precision - perfect for threaded necks and sealing surfaces.
  • Produces bottles with minimal flash and no trimming, ideal for sterile packaging.
  • Cleanroom integration: Closed mold systems reduce contamination risk.
  • Compatible with HDPE, PP, PET, and COP/COC for parenteral and sensitive formulations.
  • Supports injection molded preforms, which offer tight tolerances and uniformity.

Common pharma applications: Vials, ampoules, nasal sprays, ophthalmic bottles, mini-dose containers.

Extrusion Blow Molding (EBM)

EBM is favored for medium-to-large bottles and containers that require chemical resistance, like HDPE and PP bottles.

Key Capabilities:

  • High output and low-cost tooling for simple bottle shapes.
  • Multilayer capabilities (e.g., with EVOH, nylon) for barrier needs.
  • Supports in-mold labeling and handle integration.
  • Can produce containers from HDPE, LDPE, PP, and PVC, commonly used for syrups and suspensions.
  • Lower precision than IBM or ISBM but ideal for non-sterile packaging.

Common pharma applications: Oral syrups, bulk pharmaceutical liquids, suspension medications, pediatric medications.

Material Compatibility Across All Technologies

Regulatory and Cleanroom Capabilities

  • Machines are designed to meet FDA, GMP, and EU Annex 1 standards.
  • Cleanroom versions available for aseptic or sterile production.
  • Vision inspection systems for in-line defect detection (wall thickness, black specks, contamination).
  • Integration with track-and-trace, serialization, and tamper-evidence systems.

Automation, Quality, and Flexibility

  • Fully integrated systems for blow molding, filling, sealing, and packaging.
  • Automated mold changes for multi-SKU production.
  • Advanced robotic bottle handling to prevent human contact in sterile zones.
  • Quick format changes for clinical trials or short production runs.
