Revealing the safety of pharmaceutical packaging: the application of tensile testing machines in material testing

In the pharmaceutical industry, the selection and testing of packaging materials are crucial to ensuring the safety of drugs. Pharmaceutical packaging should not only protect drugs from external contamination and damage, but also ensure convenience and safety during use. In this process, the tensile testing machine has become an indispensable testing tool. It plays a key role in evaluating the softness of the bottle body, nozzle pull-out force, cap pull-out force, the compatibility of the combined dosing tube and the push rod, the sheath pull-out force, the heat-sealing strength of the polyethylene heat-sealed gasket, and the gasket bursting force of the pharmaceutical packaging material.

1. Bottle softness and tensile testing machine

Bottle softness is an important indicator of pharmaceutical packaging materials, which directly affects the consumer's experience. A bottle that is too soft may cause the drug to deform or even break during transportation; while a bottle that is too hard may increase the difficulty of opening and affect the convenience of use. Through the tensile testing machine, we can accurately measure the deformation of the bottle body under different pressures, so as to evaluate whether its softness meets the requirements.

2. Nozzle pull-out force and drug safety

The nozzle is an important component of liquid drug packaging, and its pull-out force is directly related to the safety of drug use. If the nozzle pull-out force is too small, the nozzle may accidentally fall off during use, causing drug waste or even accidental ingestion; while excessive pull-out force may increase the difficulty of use, especially for the elderly and children. Using a tensile testing machine, we can accurately measure the pull-out force of the nozzle and make targeted improvements based on the test results.

3. Cap pull-out force and packaging sealing

The cap is a common accessory in drug packaging, used to protect the nozzle or bottle mouth from contamination. The pull-out force of the cap is also one of the important indicators for evaluating the sealing of the package. If the pull-out force of the cap is too small, the package may be accidentally opened during transportation or storage, affecting the safety of the drug; while excessive pull-out force may increase the difficulty of opening. By testing the pull-out force of the cap with a tensile testing machine, we can ensure that the sealing of the package meets the standard requirements.

4. Compatibility of combined dosing tube and push rod

Combined dosing tube is a form of drug packaging that integrates nozzles, push rods and other components. It is widely used in situations where the amount of drugs needs to be accurately controlled. In this form of packaging, the compatibility of the push rod and the dosing tube is crucial to ensure the accuracy and safety of drug use. Using a tensile testing machine, we can test the compatibility of the push rod and the dosing tube, including indicators such as the sliding resistance and stability of the push rod to ensure that it meets the use requirements.

5. Sheath pull-out force and packaging safety

The sheath is an accessory used to protect the drug packaging from external impact and wear. The pull-out force of the sheath is also directly related to the safety of the packaging. If the pull-out force of the sheath is too small, it may cause the sheath to accidentally fall off during use and lose its protective effect; while excessive pull-out force may increase the difficulty of removing the sheath. By testing the pull-out force of the sheath with a tensile testing machine, we can ensure that the fixing effect of the sheath meets the use requirements.

6. Heat-sealing strength and sealing of polyethylene heat-sealed gaskets

Polyethylene heat-sealed gaskets are commonly used sealing materials in pharmaceutical packaging, and their heat-sealing strength directly affects the sealing performance of the packaging. By using a tensile testing machine to test the heat-sealing strength of the gasket, we can evaluate whether the bonding force between the gasket and the packaging material is strong enough to ensure that the medicine is not contaminated by the outside world during storage and transportation.

7. Gasket bursting force and opening convenience

The gasket bursting force is one of the important indicators for evaluating the opening convenience of pharmaceutical packaging. Excessive bursting force may cause difficulty in opening and affect the user experience; while too small bursting force may reduce the sealing performance of the packaging. By testing the gasket bursting force with a tensile testing machine, we can ensure that the pharmaceutical packaging has appropriate opening convenience while maintaining good sealing.

In summary, the tensile testing machine plays an important role in the detection of pharmaceutical packaging materials. By accurately measuring key indicators such as bottle softness, nozzle pull-out force, cap pull-out force, compatibility of combined dosing tube and push rod, sheath pull-out force, polyethylene heat-sealed gasket heat-sealing strength and gasket rupture force, we can ensure that the quality of pharmaceutical packaging materials meets standard requirements and provide strong protection for the safety and convenience of pharmaceutical use.
