Pet bottles are widely used for packaging of different materials and products such as food products, soft drinks, and other beverages. The manufacturers of these PET bottles need to ensure that they provide the best quality of products to the clients to ensure best safety and freshness of the products. For this, there are several different tests that must be performed on the PET bottles to test their strength, integrity, and quality. A major property of a PET bottle is its seal security that makes them appropriate for different products. To ensure that the products in a bottle stay safe and unadulterated then it is essential to make sure that the bottles are sealed efficiently, and the seal does not break during the storage or transportation.
Why is seal Important?
The seal in PET bottle is important as most of the products packaged in these bottles are in liquid form, and if the seal of the bottle is not integrated, then it can cause leakage of the products. In addition to that, the products in the bottle can easily be adulterated. The seal of the bottles must be made in such a way that it does not break easily until it is opened by the user.
Testing of the security of seal
In order to ensure that the bottle is sealed correctly, an instrument called Secure Seal Tester is used. The instrument uses pressurized air to test whether the seal of the bottle is intact or not. The test is conducted at a pressure of 175 psi with the test sample immersed in water. If the sample produces air bubbles when immersed in water, then this means that the seal is not intact, and it must be discarded.
