How to seal a 95kPa bag

Sealing a 95kPa bag typically involves ensuring the gas or pressure inside the bag remains stable and preventing the outside environment from affecting its contents.

Common sealing methods and steps:

Choose appropriate sealing materials:

Use pressure-resistant and airtight bag materials, such as polyethylene (PE), polypropylene (PP), aluminum foil film, etc., which can effectively maintain the pressure in the bag.

The 95kPa pressure bag can ensure that the sealing strip of the bag is strong enough to avoid pressure leakage caused by poor sealing.

Use vacuum packaging:

Vacuuming: It is necessary to maintain negative pressure in the bag, use a vacuum packaging machine to extract the air in the bag, and ensure that the pressure in the bag is lower than the external atmospheric pressure. The vacuum packaging machine can effectively extract the air in the bag and seal it.

Maintain a certain pressure: If you need to maintain a certain pressure in the bag (for example, 95kPa), you can adjust the air pressure in the bag through a dedicated pressure regulating device or a vacuum pump, and ensure that the sealed bag does not leak.

Heat sealing technology:

Heat sealer: Use a heat sealer to seal the bag by heating and pressurizing. The temperature and pressure settings of the heat sealer should be adjusted according to the characteristics of the bag material to ensure that the seal is firm and leak-proof.

Heat sealing method: By heating the sealing area, the bag opening is fused to form a strong sealing strip by utilizing the melting characteristics of the bag material. At this time, it is important to control the temperature and sealing time to avoid overheating or overcooling that may cause a loose seal.

Use pressure sealing equipment:

If you need to ensure that the air pressure of the 95kPa specimen bag remains unchanged, you can use a sealing device with a pressure regulating function. This type of equipment can adjust the internal pressure during the sealing process to ensure that the pressure inside the bag is stable.

Check the seal quality:

Pressure test: Through the air pressure test, ensure that the bag is well sealed and can withstand and maintain a pressure of 95kPa.

Visual inspection: Check whether the sealing strip is uniform and free of defects to ensure that there is no leakage.

Replenishing gas:

If the gas pressure in the bag needs to be maintained at 95kPa, a gas inflation device can be used to replenish or adjust the gas pressure in the bag to ensure stability.

Use a gas pressure monitor to monitor the pressure in the bag in real time to ensure that it is always within the required pressure range.

To ensure the sealing of the 95kPa transport bag, it is necessary to select appropriate packaging materials, use vacuum or pressure regulation equipment, use heat sealing technology to seal the bag mouth, and pass strict testing to ensure that the bag can stably maintain the required air pressure.
