1、 Article Introduction
This article focuses on the theme of "TST electronic tensile testing machine: expert in testing the pressure resistance performance of pharmaceutical composite film bags", and explores in depth the application of TST electronic tensile testing machine, PLC controlled electronic tensile testing machine, touch screen tensile testing machine, and precision ball screw tensile testing machine in the testing of the pressure resistance performance of pharmaceutical composite film bags, in order to safeguard the quality of drug packaging.
2、 Factors affecting the pressure resistance of medicinal composite film bags
The pressure resistance of medicinal composite film bags is influenced by various factors. Firstly, the selection of materials is crucial. Different materials have different mechanical properties and compressive strength. Plastic materials such as polyethylene and polypropylene have relatively weaker compressive strength, while metal materials such as aluminum foil have stronger compressive strength. Secondly, the structural design of the film bag will also affect its pressure resistance performance. Reasonable structural design can improve the compressive strength of the membrane bag, such as adding reinforcing ribs and using multi-layer composite structures. In addition, the production process also has a significant impact on the pressure resistance performance, such as heat sealing process, composite process, etc. If the heat seal is not firm or the bonding force between the composite layers is insufficient, it will reduce the pressure resistance of the film bag.

3、 Working principles and application scenarios of different types of TST testing machines
TST electronic tensile testing machine: By measuring the deformation of the membrane bag under pressure through sensors, the compressive strength can be calculated. Suitable for pressure resistance testing of various medicinal composite film bags, single or multiple data tests can be conducted.
PLC controlled electronic tensile machine: using PLC for automation control to achieve precise pressure loading and data processing. Mainly used for quality inspection in large-scale production, it can quickly and accurately complete a large number of testing tasks.
Touch screen tensile testing machine: Operated and parameter set through the touch screen, intuitive and convenient. Suitable for enterprises with high requirements for operational convenience, it can be used for small and medium-sized production testing.
Precision ball screw tensile machine: Adopting a precision ball screw transmission system, it ensures displacement accuracy and stability during the testing process. For drug packaging testing with high pressure resistance requirements, more accurate test results can be provided.

4、 The importance of TST testing machine in quality control of pharmaceutical composite film bags
The TST testing machine plays a key role in the quality control of pharmaceutical composite film bags. By testing the pressure resistance performance, problems in the production process can be detected in a timely manner, providing a basis for process adjustments. At the same time, the TST testing machine can also compare and test film bag materials from different suppliers, selecting materials with better quality. In addition, regularly using TST testing machines for quality inspection can ensure the stability and consistency of products, and improve the market competitiveness of enterprises.

5、 Conclusion
In summary, the TST testing machine plays an important role in the pressure resistance testing of pharmaceutical composite film bags. Different types of TST testing machines have their own characteristics and advantages, and enterprises should choose suitable equipment according to their own needs. Through scientific pressure resistance testing, the quality of pharmaceutical composite film bags can be improved, ensuring the safe packaging of drugs.
