Test method for pressure resistance performance of composite bag for aseptic packaging of liquid food
Abstract: Aseptic packaging of food means that the sterilized food is packaged in a sterile environment and enclosed in a sterilized container to obtain a long shelf life without preservatives and without refrigeration. Zui retains the original nutrients and flavors of the food to a large extent. The testing items and requirements are also very comprehensive to ensure that the contents are well protected during transportation and storage.
Keywords: aseptic packaging of foods, aseptic packaging bags, aseptic packaging, composite bags Â
Significance: The compound bag for aseptic packaging of liquid food is one of the main packaging containers for aseptic packaging of liquid foods. It has a large application and broad development prospects.
The implementation standard is GB 18454-2001 "Composite bag for aseptic packaging of liquid food". The standard specifies the technical requirements, inspection methods, inspection rules, packaging, marking, transportation and storage of composite bags for liquid food aseptic packaging.
The standard applies to bags that are lining or unlined, sterilized, and aseptically packaged for liquid foods, made of plastic and plastic or plastic and aluminum foil.
According to the standard: GB 18454-2001 "Composite bag for aseptic packaging of liquid food"
Standard requirements: pressure resistance of the bag
Sample Sample: Yantai, a company providing 15L sample 4, 50L samples 4, Mengniu food ingredients juice supplier
Test equipment: Jinan Saicheng Electronic Technology Co., Ltd. LSSD-01 leakage and seal strength tester
Test principle: By injecting a certain pressure gas into the sample, after a certain pressure holding time, the instrument automatically judges whether the sample is sealed or the large pressure value is blasted.
Instrument parameters:
Positive pressure design principle, simple operation, stable and reliable performance
Dual test method for expansion inhibition and expansion non-inhibition
Burst test, creep test, creep to crack test, multiple test mode selection
The test process "one-click" operation, intelligent, high test efficiency
Test data high-definition large-screen LCD display, automatic statistics, printing
Test range: 0 ~ 250kPa; 0 ~ 36.3 psi (standard)
0 to 400 kPa; 0 to 58.0 psi (optional)
0 to 600 kPa; 0 to 87.0 psi (optional)
0 ~ 1.6MPa; 0 ~ 232.1psi (optional)
Air source pressure: 0.4MPa ~ 0.9MPa (air source user-supplied)
Air source interface: Ф 6mm polyurethane tube
Dimensions: 300 mm ( L ) × 310 mm ( B ) × 180 mm ( H )
Test stand size: 305 mm ( L ) × 356mm ( B ) × 325mm ( H )
Power: AC 220V 50Hz
Experimental procedure:
- Install the custom fixture on the LSSD-01 Leakage and Seal Strength Tester and set the instrument parameters.
- Fix the test specimen to the instrument fixture and check that it is installed.
3. Turn on the testing machine, inflate the test sample, and after inflating a certain pressure, inspect all parts of the bag by smearing method to see if there is any air bubble. Continue to increase the inflation pressure until the bag breaks and record the rupture pressure.
4. Repeat the above test to test the remaining samples, record the different blasting values ​​separately, and take the small blasting value of each size.
Test results: 4 samples of 15L , pressurized to 20kpa , pressure for two minutes, no leakage, no cracking.
The bursting pressure is 28kpa , 31kpa , 29kpa , 28.5kpa
4 samples of 50L , pressurized to 10kpa , pressure for two minutes, no leakage, no cracks.
The bursting pressure is 18kpa , 19.6kpa , 23kpa , 20kpa
The tested samples meet the standard test requirements.
Conclusion: Through the test of the sample, the package can be intuitively understood. After filling the contents, whether there is leakage or rupture under the condition of internal and external pressure, avoiding the use process during transportation, due to leakage penetration. Causes contamination or rupture of the contents to cause unnecessary economic losses.
LSSD-01 leakage and sealing strength tester adapters are very wide, you can customize different fixtures to test different products, open packaging bag sample device, plastic anti-theft cap sealing performance testing device, hose sealing performance testing device, aerosol valve The sealing performance test device and the like can be tested by installing different jigs.
At the same time, Jinan Saicheng Electronic Technology has its own R&D team, accepting non-standard customization to meet the needs of different customers.
Jinan Saicheng Technology expects to enhance technical exchanges and cooperation with enterprises and institutions in the industry!
