Temperature-Resistant Liquid Packaging

Professional BIB Packaging Solutions

Thermal Stability Across Process Extremes

This packaging is engineered using specialized polymer blends designed to maintain physical and barrier properties across a wide temperature spectrum. Solutions are verified for applications ranging from cryogenic storage (down to −80∘C) to Hot-Fill or Retort processing (up to 121∘C). The materials prevent brittleness at low temperatures and delamination or seal failure at elevated temperatures, ensuring product containment throughout the required thermal chain.

Integrity Maintained in Extreme Conditions

LPS offers robust liquid containment solutions essential for processes involving rapid or extreme temperature changes, such as pasteurization, freezing, or high-heat sterilization. Our packaging guarantees that the structural integrity of the container remains sound, protecting the liquid from thermal stress damage and preserving its quality during critical processing stages.

Specification Details

Low Temp RatingDown to −80∘C (Specific Cryo-Grades)
High Temp RatingUp to 121∘C (Retort/Sterilization Grades)
Film MaterialCo-Polyester, PP (Polypropylene), or specialized PE co-polymers
TestingThermal shock testing and Retort process simulation
Compatible Liquid TypesAseptic concentrates, cryo-preserved media, high-pH cleaning solutions, sterilized food products.
  • Q: What material is used for cryogenic packaging?
  • A: We utilize highly specialized Ethylene-Vinyl Acetate (EVA) or certain Co-Polyester films that retain flexibility and do not exhibit the glass transition effect (brittleness) common to standard PE films at ultra-low temperatures.
  • Q: Can the packaging be retorted (high-heat sterilization)?
  • A: Yes, our retort-grade packaging uses Polypropylene (PP) or specific PET laminates that maintain structural integrity and barrier function under steam sterilization conditions (typically 121∘C for 20 minutes).

Structural Focus

  • Film Layers: Use of high-temperature polymers like PP on the contact layer.
  • Venting: Specialized self-sealing vent patch for steam or gas release during retort cycles.
  • Fitment: High-temperature resistant PP or PTFE (Teflon) fitments.
  • Casing: Autoclavable plastic or stainless steel outer container.

Material & Process

Materials: Polypropylene (PP) Homo-polymers or Co-polymers and high melt strength PE. Processing involves precise Thermal Sealing with monitored residence time to ensure 100% seal strength, followed by batch retort validation where applicable.
