1、 Article Introduction
This article focuses on the theme of "TST testing machine helps to improve the heat sealing strength 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 detection of heat sealing strength of pharmaceutical composite film bags, in order to safeguard the quality of drug packaging.

2、 The influence of heat sealing process on the heat sealing strength of medicinal composite film bags
The heat sealing process of medicinal composite film bags directly affects the heat sealing strength. The heat sealing temperature, time, and pressure are key factors. If the heat sealing temperature is too high, it may cause excessive melting of the film bag material and a decrease in heat sealing strength; If the temperature is too low, the heat sealing will not be sufficient, and the heat sealing strength will also be insufficient. Short heat sealing time can also lead to weak heat sealing; If the time is too long, it may damage the film bag material. The heat sealing pressure also needs to be moderate, as too much or too little can affect the heat sealing strength. In addition, different film bag materials have different requirements for the heat sealing process, which need to be adjusted according to the characteristics of the material. Therefore, accurate control of heat sealing process parameters is crucial for improving the heat sealing strength of pharmaceutical composite film bags.

3、 Working principles and application scenarios of different types of TST testing machines
TST electronic tensile testing machine: measures the tensile strength of the heat sealed area through sensors, and determines the heat sealing strength based on the tensile value. Suitable for heat sealing strength 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 tensile testing and data processing. Mainly used for quality inspection in large-scale production, it can quickly and accurately complete a large number of testing tasks.

Precision ball screw tensile machine: using precision ball screw transmission to ensure high precision and stability during the testing process. Suitable for drug packaging testing with high requirements for heat sealing strength.

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 detecting the heat sealing strength, problems in the heat sealing process can be identified in a timely manner, providing a basis for adjusting the production process. 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.
