Aseptic Film Technology for Liquids

Professional BIB Packaging Solutions

Sterile Barrier Integrity and Process Compatibility

Our aseptic film is engineered to withstand and maintain integrity through terminal sterilization processes (e.g., E-beam, Gamma, or H2​O2​ wash) before filling. The film structure—often EVOH or Foil-based—is designed to provide an absolute microbial barrier and ultra-low OTR (Oxygen Transmission Rate) for extended ambient storage. The film surface is smooth and non-porous, reducing the risk of microbial adherence and facilitating efficient sterilization.

Guaranteeing Microbial Stability

LPS provides cutting-edge aseptic film solutions crucial for the safe, non-refrigerated distribution of perishable liquids. By controlling every variable from film composition to fitment welding, we ensure that the packaged liquid maintains commercial sterility and verifiable quality for extended periods, opening up global logistics opportunities and reducing cold chain dependency.

Specification Details

Sterilization MethodE-beam, Gamma Irradiation, or Hydrogen Peroxide Compatible
Microbial BarrierAbsolute Seal Integrity Post-Sterilization
Shelf Life Target6 to 18 Months Ambient
Film StructureEVOH or Aluminum Foil High Barrier Laminate
Compatible Liquid TypesAseptic fruit and vegetable purees, UHT milk, liquid sugar, wine concentrates.
  • Q: What verification is performed on the aseptic film?
  • A: We conduct rigorous testing including seal integrity tests, flex crack resistance tests, and microbial challenge tests to validate the film's ability to maintain a sterile barrier post-processing.
  • Q: Is aseptic film designed to be retortable?
  • A: While aseptic filling achieves sterility before sealing, we offer specialized aseptic films that also possess the necessary thermal stability (PP contact layer) to withstand subsequent mild pasteurization or hot-fill processes.

Structural Components

  • Aseptic Liner: Multi-layer barrier film with high EVOH or Foil content.
  • Aseptic Fitment: Specialized spout and gland system compatible with sterile docking or CIP (Clean-in-Place) filler heads.
  • Outer Casing: Sterile handling tray or corrugated box.
  • Tamper Evidence: Sealed port or tear-off ring closure.

Material & Assembly Process

Materials: LLDPE contact layer with NYLON/EVOH/PET or Foil barriers. Process: Automated bag conversion and fitment welding in an ISO Class 7 cleanroom, followed by validated terminal sterilization (e.g., Gamma irradiation) and sterile packaging.

Purity and Logistical Advantages

  • Preservative-Free: Enables clean label status by allowing safe ambient storage without chemical preservatives.
  • Process Compatibility: Validated films and fitments seamlessly integrate with existing aseptic filling machinery.
  • Global Distribution: Eliminates the significant cost and complexity of maintaining the cold chain.
  • High Barrier Retention: The film maintains its barrier properties throughout the sterilization and filling processes.

Application Industries

  • Juice & Beverages: Long-life fruit concentrates, vegetable purees, and tropical juices.
  • Dairy Alternatives: UHT milk and plant-based beverages.
  • Food Ingredients: Aseptic liquid egg, food flavorings, and colorants.
  • Pharmaceutical: Non-injectable liquid media and buffers.
