Test Principle Of Candy Seal Bag Leak Detector Negative Pressure Sealer

Test principle of candy seal bag leak detector negative pressure sealer

Negative pressure sealer: The tightness of food packaging is a concern of the food industry. With the increasing material life, people's requirements for the packaging of goods are not only to protect the goods from damage and aesthetic requirements. At the same time, it also requires a variety of functions such as preservation, anti-corrosion, anti-bacterial, anti-counterfeiting, and extended shelf life. The negative pressure sealer is an instrument that specifically detects the sealing performance of the product. The negative pressure sealer is suitable for the sealing test of packaging bags, bottles, tubes, cans, boxes, etc. in food, pharmaceutical, medical equipment, daily chemicals, automobiles, electronic components, stationery and other industries. The negative pressure sealer can also perform the sealing performance test of the test piece after the drop and pressure test.

Negative pressure sealer test principle: by vacuuming the vacuum chamber, the sample immersed in water is subjected to internal and external pressure difference, and the gas escape condition in the sample is observed to determine the sealing performance of the sample; by vacuuming the vacuum chamber The sample is subjected to a pressure difference between the inside and the outside, and the shape of the sample is recovered after the sample is expanded and the vacuum is released, thereby determining the sealing performance of the sample.
