Packaging is an essential part of any product, as it protects the product from damage, contamination, and spoilage. However, packaging can also have defects, such as leaks, that can compromise the quality and safety of the product. Therefore, it is important to test the integrity and reliability of the packaging materials and products before they are shipped and delivered to the customers.
One of the most effective and efficient ways to test the leaks in packaging products is by using a vacuum leak tester. A vacuum leak tester is a device that creates a vacuum inside a chamber and detects any leakage of air or gas from the packaging product. It can be used to test various types of packaging products, such as bottles, pouches, cans, trays, and more.
One of the best suppliers of vacuum leak testers for the packaging industry is Presto Group. Presto Group is a leading manufacturer and supplier of testing instruments and equipments for various industries, such as packaging, paper, plastic, textile, metal, and more. They have over 40 years of experience and expertise in providing testing solutions to the world.

The vacuum leak test from Presto Group work on the principle of creating a vacuum inside a chamber and detecting any leakage of air or gas from the packaging product. The machine consists of a base unit, a vacuum chamber, a specimen holder, a pressure gauge, a display unit, and a control unit. The working principle of the machine is as follows:
• The packaging product is placed on the specimen holder and secured with clamps.
• The vacuum chamber is closed and the vacuum pump is switched on to create a vacuum inside the chamber.
• The pressure gauge measures the pressure inside the chamber and sends the signal to the display unit.
• The display unit shows the pressure inside the chamber and the test result on the LED screen, and also stores the data in the memory.
• The test result is calculated as the difference between the initial pressure and the final pressure inside the chamber, which indicates the amount of leakage from the packaging product.
The vacuum leak testers from Presto Group can be used for various applications in the packaging industry, such as:
• Testing the quality and reliability of packaging products, such as bottles, pouches, cans, trays, and more.
• Testing the compliance of packaging products with the national and international standards and regulations for packaging quality and safety, such as ASTM F2338, ASTM D6653, ASTM
D4991, ISO 15105, and more.
• Testing the suitability of packaging products for different purposes and functions, such as sealing, storing, transporting, and more.
