[0002] The main advantage of using roll film in the packaging industry is that it saves the cost of the entire packaging process. When used in automatic packaging machinery, roll film does not require the packaging manufacturer to perform any edge sealing work. Only a one-time edge sealing operation is required at the manufacturer. After the roll film is produced, a series of tests are required to prevent various quality problems. A roll film tensile strength testing device is required for roll film testing.

[0003] However, due to the existing tensile strength testing device, it is difficult to pull and fix the roll film when testing the tensile strength of the roll film, which may cause the roll film to fall off, affecting the testing efficiency of the roll film. Directly using a motor for power transmission to fix the roll film is relatively costly. Therefore, we propose a roll film tensile strength testing device to solve the above problem.
