If you are looking for cheap, (semi-) airtight containers you might want to look at tupperware/icecream boxes. You don't need a fancy high end solution, your parts wont cease to function if they are exposed to a little bit of humidity. As long as you don't pack the components while you're showering you will be fine. If you don't want to use silica gel (or any other desiccant) you have to get rid of the moisture that is still inside the container. A good way to do this would be to heat the container to 75 °C for 6-12h before you put anything in (although that is really not necessary for your use). Btw, if your container is airtight you only need the silica to get rid of the initial moisture, so you only need a small amount (a few grams). (The absolute best solution would be to put your electronics inside a Schott laboratory glass bottle while everything is inside a glovebox that actively removes moisture, that way you can store it for years at sub-ppm levels of humidity. Is this a practical solution? Absolutely not.) |

I store my video game cartridge inside an open anti-static bag, this open anti-static bag is inside a closed shoe box and inside that box I put 3 silica gel sachets inside the box and will the bag condense moisture and damage the cartridge? what can i improve for two months i receive in my home silica gel and ziplock bag? |

So it depends where that box is, which temperature swings the container will be subject to and which temperature your parts have if you want to avoid them actually getting wet and corrode. It might be better to store them pretty much open inside a home, as the construction and wood furniture itself buffers humidity to some extent, while the anti static bag buffers nothing. If the building wouldn't, it would become moldy pretty quick. Some desiccants do not only saturate and are useless afterwards, they might as well buffer the humidity and extend the range before condensation will visibly happen depending on the amount of air (and therefore absolute humidity). Ofc they are more capable to do so when dry. |

If you seal the bag, make sure first that you do it in a dry environment else you will trap moisture. That's why silica gel is used, to absorb moisture that can corrode electronics. --- End quote --- Not quite. You need to think about relative humidity. If the bag is sealed, the number of water molecules remains constant. Whether they are in solid, liquid or gaseous form depends on the temperature. The temperature at which they condense into liquid depends on the relative humidity and temperature when the bag was sealed. |
