PET bottles are the ideal packaging material which is used to store the liquids & transport the goods safely from one place to another. Nowadays the manufacturers in every beverage industry prefer to use PET containers for packaging as they are totally safe and resist any type of spillage or leakage of products. They have completely replaced the techniques of traditional packaging such as glass bottles and other mediums due to their various advantages like strength, economy, and easy handling. With rising demand, the quality testing became a major factor for the manufacturers. Hence, quality testing is now a vital section of the production process. In this blog section, we will discuss one of the widely used test methods for containers, i.e. the torque test for bottle caps using a digitally based torque tester.

Why is the quality testing important?

Most of the bottles and containers are subjected to leakage and spillage, therefore; it is necessary for the manufacturers of PET bottles to ensure that the containers they are manufacturing are best in terms of quality. Any type of defect which is found in bottles directly affect the safety, hygiene, and quality of the product that is packed inside. Therefore, it is mandatory to ensure that the bottles have gone through the stringent quality check standard with the help of highly accurate and efficient quality testing machine so that there will be no threat of hygiene in the mind of the customers related to the product.

Testing Torque in Bottle Caps

Bottle caps play a significant role to test the quality of the bottles. If the lids and caps of bottles are not tightened appropriately or inferior in terms of quality, then it will directly affect the safety of the products.

To measure the integrity and intactness of the bottle caps,  Torque tester is used. At the time of testing, the bottle is placed between the solid grips that comprise of load sensors and the cap of the bottle is opened manually to measure that how much strength is required to open the cap of the bottles.

When sufficient amount of force is applied to the lids of the bottle, it provides opposite pressure to the bottles that are captured by a load sensor and display on the digital panel. This testing procedure of the tester helps to measure the minimum strength which is required to open the bottle caps.
