Since the early 1980s, plastic bottles are used as packaging materials for detergent, beverages and various other consumer goods. The plastic bottles have many advantages such as easy to produce, toughness, and energy savings etc. They are economical and recyclable as well.

Plastic containers are better than glass containers due to ruggedness and resiliency. The same resilience makes plastic bottles improbable to leak and protects the contents along with exterior shipping cartons. The demand for PET bottles is increasing which is proved by looking at the figures below:

  • As per resources, the total production of PET bottles in the world was 485 billion bottles in 2016.
  • It has increased to 583.3 billion bottles worldwide by 2021.
  • It also reveals that about one million plastic bottles were sold every minute worldwide in 2017.

Therefore, manufactures should test the quality and integrity of packaging products. To test this requirement, a well-known device i.e. Vacuum Leak Tester must be used. The instrument test the PET products for all sorts of leakage in the products. The vacuum leak tester tests the sample under vacuum. The instrument is available for both PET bottles and pouches to assure a better quality of packaging to the manufacturers and suppliers all over the world. It also supports the best level of hygiene and safety to the products packed inside.

 

Procedure to test the sample is very easy. It is used to test the quality of the PET bottles by giving a high amount of pressure. The sample is put into a large quantity of vacuum and analysed for further development and deformation of bubbles within the test samples. In this way, any leakage and pinholes are identified.

Vacuum Leak Detectors is a reliable tool that provides visual determination for the integrity of foiled cups, gels, and pouches that are tested under vacuum. A set amount of vacuum is created inside the chamber to measure the integrity to evaluate the leak proofs of foil packaging. It ensures intactness of closures.

Some of the features of vacuum leak tester are:

  • Displays the generated vacuum on the screen
  • Digital pressure display for easy pressure monitoring
  • Stainless steel body and corrosion resistant finish
  • Adheres to standards such as ASTM D 4991-07(2015), ASTM F 2338-09(2013), ASTM D6653, ASTM D3078 and ASTM D5094
  • Inlet vacuum pressure setting, pressure and pre-set timer function
