If you have a PET bottle, you may be using it without ensuring about its leakage, and then you should think twice. PET or Polyethylene terephthalate is not only strong and stiff but also flexible material that can be made into everything from bottles to cables with all sorts of wonderful properties like durability, kept in mind. When creating PET bottles, the manufacturing process starts with the injection molding of polyester resin pellets to produce thin strands called “tows”. These tows are then stretched and heated until they become clear thermoset material. This is what forms the bottle's structure. There are many reasons why you may want to test vacuum leakage in PET bottles. For one, if your product is carbonated and the seal on the bottle leaks then it will cause a buildup of pressure that can result in an explosion. The other reason is that ethylene gas could be escaping from your bottle which can lead to spoilage or contamination of any liquid stored inside. If you're unsure about what type of equipment to use for testing the PET bottle, then we will help you.

It comes with vacuum adjustability up to 600 mm-Hg (800 Mb) with a 2-stage vacuum and holding time setting. It has an inbuilt vacuum generator that will easily test the vacuum leakage in PET bottles. Now, let us dig deep into the information about this testing machine from Testronix.

Introduction about vacuum leak tester for bottles

The vacuum leak tester is a precise testing instrument offered by Testronix that is used by many packaging industries and Pet manufacturing industries for testing the quality of the pouches and PET bottles. In the packaging industry, the leakage in PET bottles would lead to the disruption of material inside them. Thus, it is important to check the durability of these bottles and ensure that there is no leakage present. To test this, you can make use of the Testronix vacuum leak tester that will help to test the seal integrity of PET bottles. During the testing procedures, the test sample is placed in its place and then a specified amount of vacuum is created in the sample. After the vacuum is created in the sample, it becomes easy to test any leakage in the test sample with great accuracy. When the test specimen is placed under vacuum, if there is a leakage in the seal of the specimen, it will deform or shrink indicating the presence of leakage in the specimen. The test is performed in order to ensure that the packaging offered to the clients is free from any leakage and is completely intact.
