Mfy-01is designed and manufactured according to the GB/T 15171-94 soft packing performance test method, which is suitable for the sealing test of soft packaging in industries such as food and pharmaceuticals. The test can effectively compare and evaluate the sealing process and sealing performance of the soft packing parts, and provide the scientific basis for determining the relevant technical requirements.

Mfy-01 type sealing tester is a kind of heat sealing property and processing technology that USES compressed air to generate negative pressure through vacuum original group to detect and test plastic soft packaging materials. The instrument for quality and reliability of the plastic seal provides an advanced, practical and effective test method, the operation is simple, instrument appearance, novel and unique design, easy to observe the test result, especially to tiny pores on the sealing leakage detecting quickly and efficiently.

2. Structure characteristics and working principle

2.1 structural characteristics

It consists mainly of special transparent vacuum chamber (organic glass bucket), vacuum system, compressed air source (the customer has the gas pressure of 0.2-0.9 MPa), pressure gauge and so on.

2.2 working principle

Through to the vacuum chamber, vacuum leaching test sample in the water produced inside and outside differential pressure, vacuum indoor observation test sample gas to escape or water infiltration, inward test to determine the sealing performance of the sample.

Working principle: the packing inside and outside the packaging to gas expansion, the difference between the gas pressure gas escape to a new equilibrium - high proportion of the gas inside the packaging - gas expansion rate big - packaging film under pressure, gas evolution.

Note: the setting of parameters should be determined by the air ratio in the product, the air ratio is high, the gas expansion rate in the package is high, and the vacuum pressure should be set lower.
