PET bottles are widely used in packages for delivering a different variety of products. These bottles are lightweight, shatterproof, and cost-effective nature making them ideal for packaging everything from drinks to food items. But what if the bottle caps will be loosened? This will lead to damage to the product and also affect the business’s reputation. Thus, to overcome this issue, it is important for PET bottle manufacturers to test the quality of PET bottles by testing their torque value. We at Presto have designed a high-quality torque testing instrument that is used to test the torque ability of the boxes and ensure that quality materials will be delivered to the customers.

The torque tester digital has strong clamping pegs/holders for zero grip slipping support. Users will get a highly accurate value of torque and ensure that the quality of materials will be delivered. In this blog, we are going to provide you with information about torque testers and how you can easily conduct torque strength tests on PET bottles. So, let us get started!

Why torque testing of PET bottles is important?

The torque test of the PET bottles is an important part of quality control that will help manufacturers to test whether the material is strong enough against the opening and closing torque of PET bottles. The torque test measures the amount of force required to twist the cap of a bottle opener. This test is important because it can help determine whether a bottle is likely to break or leak when it is under pressure.

This quality test can be done with the help of a torque tester for PET bottles. Presto offers high-quality torque strength testing instruments that will help the manufacturers in ensuring the quality of PET bottles.

This testing equipment is ideal to be used in the bottle testing industry. Users will easily test different materials against torque testing that includes CT bottle caps, closure caps, child-resistant bottle caps, and many more. You can read more on the importance of torque testing the PET bottle accurately.
