According to the State Food and Drug Administration's <<Compilation of Standards for Packaging Materials and Containers in Direct Contact with Pharmaceuticals, Volume VI>>, the physical properties that need to be tested for three-layer co-extruded infusion films (I) and bags, and five-layer co-extruded infusion films (I) and bags are: [b]I. Water Vapor Transmission Rate Test[/b] The test shall be conducted according to the Water Vapor Transmission Rate Determination Method (YBB00092003), Method I (Cup Method). Under conditions of 38℃±0.6℃ and relative humidity of 90%±2%, the permeability should not exceed 5.0 g/(m2·24h). Jinan Langguang Electromechanical Technology Co., Ltd. provides the following testing instruments for reference: 1. TSY-T1H type moisture permeability tester: Performs the cup method standard, three-chamber test. Fully automatic measurement, with built-in micro printer, convenient operation, short test cycle, and high efficiency. 2. TSY-T3 type moisture permeability tester: Performs the cup method standard, the world's only twelve-chamber fully automatic tester, high efficiency. Short test cycle, more suitable for large-volume testing requirements. [b]II. Oxygen and Nitrogen Permeability Tests[/b] Both indicators must be measured according to the Gas Permeability Measurement Method (YBB00082003) Method 1 (Differential Pressure Method), where the oxygen permeability should not exceed 1200 cm3/(m2·24h·0.1MPa), and the nitrogen permeability should not exceed 600 cm3/(m2·24h·0.1MPa). Jinan Langguang Electromechanical Technology Co., Ltd. offers the following testing instruments for reference: 1. VAC-V1 Differential Pressure Gas Permeation Analyzer: This analyzer operates on the differential pressure principle and can test the permeation rate of gases such as oxygen, nitrogen, and carbon dioxide. It features self-temperature control (temperature range: room temperature to 50℃) and a data acquisition function, allowing for the acquisition of data on material permeability, permeability coefficient, solubility coefficient, and diffusion coefficient at temperatures ranging from -273℃ to 200℃. Testing mode: Single-chamber testing. 2. VAC-V2 Differential Pressure Gas Permeation Analyzer: This analyzer operates on the differential pressure principle and can test the permeation rate of gases such as oxygen, nitrogen, and carbon dioxide. It features self-temperature control (temperature range: 5℃ to 75℃) and a data acquisition function, allowing for the acquisition of data on material permeability, permeability coefficient, solubility coefficient, and diffusion coefficient at temperatures ranging from -273℃ to 200℃. Testing mode: Three-chamber testing. 3. The VAC-V3 differential pressure gas permeation analyzer operates on the principle of differential pressure and can test the permeation of gases such as oxygen, nitrogen, and carbon dioxide. It features self-temperature control with a range of 5℃ to 75℃ and a fitting function, allowing for the acquisition of data on material permeability, permeability coefficient, solubility coefficient, and diffusion coefficient at temperatures ranging from -273℃ to 200℃. The test mode is a six-chamber test. [b]III. Heat Seal Strength[/b] The heat seal strength is determined according to the method for composite bags in the heat seal strength determination method (YBB00122003). The average value of each heat-sealed part should not be less than 20N/15mm. Jinan Langguang Electromechanical Technology Co., Ltd. provides the following instruments for reference: 1. XLW Intelligent Electronic Tensile Testing Machine. Testing functions include: heat seal strength, tensile strength and deformation rate, breaking force and deformation rate, tear strength, shear strength, 180-degree peel strength. With puncture and opening force clamps, it can perform opening force and puncture force tests on the interface of large infusion bags. It can communicate with a computer through professional supporting software. 2. The XLW (PC) intelligent electronic tensile testing machine's testing functions include: heat seal strength, tensile strength and deformation rate, breaking force and deformation rate, tear strength, shear strength, and 180-degree peel strength. With the addition of puncture and opening force clamps, it can perform opening and puncture force tests on large infusion bag interfaces. The instrument has a longer stroke than the XLW intelligent electronic tensile testing machine, making it more suitable for tensile testing of materials with large deformation rates. It offers higher precision, and the standard configuration includes a computer and professional software.
