Presto’s Vacuum leak tester deliberately complies with International Quality Standards. The instrument is used to check the reliability of the foiled cups under vacuum visually. For performing a test, a definite vacuum is created in the chamber to assess integrity for the purpose of the leaking proof of the foil packaging. The test is done to assure that the seals are not damaged. It is a procedure performed before storage and warehousing.
A defined vacuum is engendered in the chamber to gauge the reliability for the strength of the leak-proof resistance of foil packaging. This is prepared in order to support that the seals are unbroken, it is principally the last test performed before warehousing and storage. A leaky seal is considered as the failure of the product. A leaky seal results in the spoilage of the contents packed inside. Due to leakage, the environmental factors start to affect the quality of the contents packed. If a tetra pak has leaky seal, the spores might enter the packing and spoil the liquid. Thus, having a vacuum leak test before starting mass production in the industry.
