The sealing of the food packaging can be detected by the Jinan fine-based test instrument. The food packaging bag sealing tester MFY-1 is also called the negative pressure sealing instrument. It is vacuuming the vacuum chamber and the sealing of the food packaging bag. The tester makes the internal and external pressure difference of the sample, observes the sample expansion and the shape recovery of the sample after vacuum release, and the liquid infiltration condition, thereby determining the sealing performance of the sample. Therefore, controlling the sealing of food packaging has important significance for the production enterprise and the quality inspection department. The food packaging bag sealing tester 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. It can also test the sealing performance of the test piece after the drop and pressure test.
Food packaging bag sealing tester test principle:
By vacuuming the vacuum chamber, the sample immersed in water is subjected to internal and external pressure difference, and the gas escape in the sample is observed to determine the sealing performance of the sample; the vacuum chamber is evacuated to generate internal and external pressure of the sample. Poor, observe the sample expansion and release the vacuum shape of the sample to determine the sealing performance of the sample.

Operation
5.1 Inject clean water into the vacuum chamber, the height exceeds the surface of the bottom plate on the cylinder head, and put the sample. At this time, the distance between the top surface of the sample and the water surface should not be lower than 25 mm to ensure the sealing effect, and sprinkle a little water on the sealing ring.
5.2 Cover the sealing cover of the vacuum chamber, turn the switch on the tester to the open position, adjust the control adjustment knob of the tester (see above for adjustment method), observe the vacuum pressure gauge, and adjust the pressure to the stable value required for the test. .
Note: As long as the leakage of each part of the sample can be observed during the test, two or more samples can be tested at one time.
5.3 to reach the required pressure, turn the tester's switch to the off position, maintain the vacuum, the timer starts to count, observe the sample, and reach the dwell time.
Note: The adjusted vacuum value is determined according to the characteristics of the sample (such as the packaging materials used, the sealing conditions, etc.) or the relevant product standards.
5.4 Leakage of the sample during vacuuming and after the preset vacuum is reached, depending on whether there are continuous bubbles. A single isolated bubble is generally not considered a sample leak.
5.5 When the pressure holding time is reached, the switch on the instrument is turned to the off position, the vacuum is removed, the sealing cover is opened, the test sample is taken out, the water on the surface is wiped clean, and the surface damage result of the packaging bag is observed.

A digital Hotel Safe is a secure storage device found in hotel rooms that uses electronic technology to provide guests with a secure place to store their valuables. Unlike traditional hotel safes, which typically use a physical key or combination lock, digital hotel safes use a digital keypad or touchscreen interface to allow guests to set their own unique passcode.
Digital hotel safes offer several advantages over traditional safes. Firstly, they are more convenient to use, as guests can easily set and change their own passcodes without needing assistance from hotel staff. Secondly, they provide a higher level of security, as the passcodes are typically encrypted and more difficult to guess or crack compared to physical keys or combinations.
In addition to the passcode entry, digital hotel safes may also offer additional security features such as an audit trail, which records the date and time of each access attempt, as well as a tamper-proof design to prevent unauthorized access.
Digital hotel safes come in various sizes and designs to accommodate different types of valuables, such as laptops, jewelry, passports, and cash. They are typically mounted securely to a wall or inside a cabinet to prevent theft or unauthorized removal.
Overall, digital hotel safes provide guests with a convenient and secure way to store their valuables during their stay, giving them peace of mind knowing that their belongings are protected.
