Characteristics Of Medical Packaging

Excellent microbial barrier (sterile barrier) performance
Core requirement: Medical packaging must provide a reliable microbial barrier that effectively blocks the invasion of bacteria, spores, and other microorganisms throughout the entire shelf life from sterilization to clinical use, maintaining an absolute sterile state within the system.
Reflection: The material needs to have extremely fine pore size (such as below 0.45 μ m) or dense barrier structure, and must pass strict microbial barrier testing.
Strict sterilization process adaptability
Core requirement: Packaging materials must be able to withstand specific sterilization methods (such as ethylene oxide sterilization, high-temperature moist heat steam, irradiation sterilization, low-temperature plasma sterilization, etc.), and must not be damaged, deformed, or release harmful substances due to sterilization processes (such as high temperature, vacuum, chemical gases).
Reflection: The material needs to have good breathability (allowing sterilization factors to penetrate and be discharged) and heat/pressure resistance, and maintain stable performance after sterilization.
Excellent physical protection and sealing
Core requirement: The packaging must have good physical strength (tear resistance, puncture resistance, impact resistance) and sealing to protect medical devices from physical damage during transportation, storage, and handling, and to prevent external moisture, dust, and harmful gases from entering.
Reflection: Strict sealing tests (such as peel strength tests, burst tests) and transportation simulation tests (such as drop, vibration, compression tests) are required to ensure that the packaging can maintain integrity under extreme conditions.
Biocompatibility and Safety
Core requirements: Packaging materials that come into direct contact with medical devices or drugs must be non-toxic, free of heat sources, and have no hemolytic reactions. They must also not undergo chemical reactions or migrate harmful substances with the product to ensure that they do not pose a risk to patient health.
Reflection: The material needs to undergo strict biocompatibility evaluation (such as GB/T 16886.1 standard) and chemical performance testing (such as dissolution and pH value testing).
Convenient and easy to open with anti pollution design
Core requirement: The packaging should be easy for clinical aseptic opening, leaving a clear "opened" mark after opening, and without resealing to prevent secondary contamination; The opening process should minimize the generation of debris or particles to avoid contaminating medical devices or surgical environments.
Reflected in: It often adopts an easy to tear design, semi transparent white material (for easy observation of the interior), and chip free peeling material (such as Tyvek).
Clear identification and compliance
Core requirement: The packaging must have clear, complete, and non removable labeling, including product information, sterilization labeling, opening position, expiration date, and traceability information required by regulations, to ensure correct clinical use and compliance traceability.
