In this test, a hydraulic pressure is applied to the sample via a rubber diaphragm. The medium of pressure is glycerine. The pressure applied on the film is sensed by a sensor and displayed on the screen.

A good seal is the key to successful delivery. Heat sealing technique is used to form the bond. Any faulty sealing means a failed product. And sometimes due to faulty sealing techniques, the packings get puffed or leak during the transit or in the retail store. The sealing technique that is being used must have the right temperature, pressure and dwell time.

Printing should be a matter of concern. What is packed inside should be well mentioned on the outside labels? Contents, composition, allergy warnings, nutritional value are some common things that can be found commonly on a label.
