Bag-In-Box With Touch Valve(Nylon Composite)

Industry knowledge

How can manufacturers of nylon composite bag-in-box with touch valve avoid deformation or shrinkage of nylon composite materials due to high temperature during heat sealing?

Accurately control heat sealing temperature:
According to the melting temperature and characteristics of nylon composite materials, set the appropriate heat sealing temperature. Excessive temperature may cause overheating of the material, causing deformation or shrinkage.
Use advanced temperature control system to monitor and adjust the temperature of the heat sealing area in real time to ensure that it fluctuates within the set range.
Optimize heat sealing time and pressure:
Reasonable heat sealing time and pressure settings are essential to ensure sealing quality. Excessive heat sealing time or excessive pressure may increase the risk of deformation of nylon composite materials.
According to the characteristics of the material and sealing requirements, determine the optimal heat sealing time and pressure parameters through experiments and tests.
Choose appropriate heat sealing equipment:
Choose heat sealing equipment with high-precision temperature control and pressure regulation functions to improve the stability and controllability of the heat sealing process.
Ensure that the heating elements of the heat sealing equipment are evenly distributed to avoid material deformation caused by local overheating.
Use high-quality materials:
Choose nylon composite materials with good thermal stability and high temperature resistance as raw materials for bag-in-box.
Ensure the quality of materials is stable and avoid poor heat sealing and deformation caused by material quality problems.
Implement strict process control:
Develop detailed heat sealing process specifications and operating procedures to ensure that operators can operate according to standards.
Regularly inspect and maintain heat sealing equipment to ensure that it is in good working condition.
Adopt advanced heat sealing technology:
Explore and apply new heat sealing technologies, such as ultrasonic heat sealing, high-frequency heat sealing, etc., to improve heat sealing efficiency and product quality.
Reduce the risk of deformation and shrinkage of nylon composite materials during heat sealing through technological innovation.

Does the supplier of nylon composite bag in box with touch valve have corresponding sealing performance test data of nylon composite bag in box with touch valve, such as leakage rate, sealing pressure, etc.?

Leakage rate test:
Test method: The leakage rate calculation of airtightness test is mainly based on the actual leakage detected by the test equipment. The supplier may use a method similar to that described in reference article 2, that is, first apply a certain pressure (negative pressure or positive pressure) to the bag, then lock the pressure and start timing, observe and record the pressure drop (ΔP).
Data representation: Leakage rate is usually expressed as leakage per unit time, such as milliliters per second (mL/s) or Pascal liters per second (Pa·L/s). The specific value depends on the design, materials and manufacturing process of the bag.
Seal pressure test:
Test method: This may involve applying pressure to the sealed part of the bag to evaluate its ability to withstand external pressure. Specific test methods may include negative pressure tests (such as the ""bubble method"" described in reference article 3) or positive pressure tests (such as rupture tests, creep tests, etc.).
Data representation: The sealing pressure is usually expressed as the maximum pressure that the bag can withstand before rupture, or as a function of pressure and time to express the creep performance of the bag under continuous load.
