Plastic sealability tester vacuum range can be set according to need

The plastic sealability tester is applicable to the quantification of the seal strength, the heat seal quality, the burst pressure of the whole bag, and the seal leakage performance of various sealed packages such as flexible packages and aseptic packages formed by heat sealing and bonding processes. Plastic Sealing Tester Quantitative measurement of the sealing performance of various plastic anti-theft caps, the overall sealing performance of various hoses, compressive strength, the strength of the cap connection, the strength of the tripping, the strength of the heat sealing edge sealing, the strength of the bonding strength and other indicators Quantitative measurement; The plastic sealability tester can also be used for the compressive strength, burst strength, etc. of the materials used for flexible packaging bags, bottle cap torque sealing index, cap connection release strength, material stress strength, and the entire bottle body. Sealability, pressure resistance, burst resistance and other indicators were evaluated and analyzed.

Implement the GB 15171 flexible packaging sealing test standard, specifically for the sealing performance of flexible packaging. The plastic sealability tester uses the principle of vacuum negative pressure to form a vacuum, the vacuum environment is stable, and the plastic sealability tester minimizes the test error. The internal components of the equipment are all pneumatic components from Japan's original SMC company (filter pressure reducing valve, vacuum generator, liquid crystal pressure gauge, air filter, and two-way electromagnetic valve). The vacuum degree and time of the plastic sealability tester are within the allowable range and can be set as required (Strict implementation of GB 15171 at this point is different from the blasting test, especially for quality inspection institutions and research departments.)

First, the characteristics of plastic sealing tester

The system uses digital preset test vacuum and vacuum retention time to ensure the accuracy of test data

Plastic sealing tester adopts pneumatic components imported from world-renowned countries, with stable and reliable performance

The automatic constant pressure air supplement of the plastic seal tester further ensures that the test can be performed under preset vacuum conditions

Professional software supports automatic backflush unloading and automatic end of test functions. The plastic sealability tester ensures the smooth progress of the test process.

The system adopts microcomputer control, with LCD screen, PVC operation panel to facilitate the user to test operation and data viewing

Second, the plastic sealing tester test principle

The plastic sealability tester vacuums the vacuum chamber to generate a differential pressure between the inside and outside of the sample immersed in water, observes the escape of gas in the sample, and determines the sealing performance of the sample; vacuum is applied to the vacuum chamber, plastic Sealing tester makes the sample produce internal and external pressure difference, observe the expansion of the sample and release the vacuum after the shape recovery of the sample, in order to determine the sealing performance of the sample.
