What is the validity period of the meltblown cloth?

  • Release on:2021-06-30
What is the validity period of the meltblown cloth? Does meltblown cloth(Melt Blown Filter On Sales) have a shelf life? Many people are more concerned about this issue, so today we will introduce it to you.

Melt blown cloth is actually a plastic material. It is reasonable to say that plastic can have a long shelf life without being damaged. Plastic is also difficult to degrade in the natural environment. However, melt blown cloth is different from plastic in that it has a shelf life and is subject to storage conditions. The impact is relatively large.

If you are a manufacturer of masks, you will know that the meltblown cloth(Meltblown Fabric Factory) is electrostatically charged when you use the meltblown cloth. When you take the meltblown cloth by hand, you will find that it will be adsorbed on clothes or other objects. Why is the meltblown cloth charged? What?

This is increased through electrostatic electret equipment during production. If there is no static electricity, the filtering capacity of the meltblown cloth will be greatly reduced.

Because the fiber diameter of the meltblown cloth(PP Meltblown Vendor) is larger than the diameter of the virus, the meltblown cloth relies on electrostatic adsorption to adsorb the virus on the meltblown cloth.

The filtering capacity of melt blown cloth has a lot to do with static electricity. If the storage conditions are not good or the storage time is longer, then the melt blown cloth will become bad or very poor.

The shelf life of meltblown cloth has a lot to do with the raw materials produced, generally within 12-18 months, and long-term storage is not recommended.
