Are Waterproof Bags Really Waterproof?

It can be waterproof, but it is recommended to test it with a tissue before using it. Although it is waterproof, there is no guarantee that each one will be without problems. The anti-swimming wild water bags on the market are generally made of PVC and TPU. TPU is a little more expensive, the material is softer, and the touch screen effect is better.

First, pay attention to the use of time.

Any product has its most suitable use time, usually called "shelf life". Once many products exceed the "shelf life", they will deteriorate and the effect of use will be greatly reduced. So when we use the mobile phone waterproof bag, we must be careful not to use it too frequently. It is best to replace it regularly to avoid deterioration of the waterproof bag due to a long time.

Second, make full preparations before use.

When you get a waterproof bag, first of all, don't rush to put our expensive mobile phone in it. You should first fill the waterproof bag with dry paper towels, then fasten the buttons, put it in a bucket filled with water, and wait a while to test the waterproofness of this fiber waterproof bag. Finally, if you find that the paper towel is not wet, it proves that the waterproof bag can be trusted. Only in this way can you hand over your phone to it with confidence. If you find that the paper towel has wet marks, it proves that the water resistance is poor. Don't put your phone in it at this time.
