SUMMARY

This discussion centers on the effects of humidity on storing DVDs and electronic components in closed cardboard boxes. It highlights that moisture can enter these containers during humid weather, and questions whether transitioning to a hot and dry climate (31-35°C) will evaporate the moisture from the items inside. Key points include the varying rates of water molecule movement through different grades of plastic and the role of paper and cardboard in managing water vapor, which prevents local condensation.

PREREQUISITES
  • Understanding of humidity effects on materials
  • Knowledge of moisture diffusion principles
  • Familiarity with the properties of polyethylene (PE) plastic
  • Basic concepts of water vapor management in storage environments
NEXT STEPS
  • Research the impact of humidity on electronic components storage
  • Learn about moisture diffusion rates in various plastic materials
  • Investigate methods for preventing condensation in enclosed storage
  • Explore the properties of cellulose fibers in moisture management
USEFUL FOR

This discussion is beneficial for collectors of DVDs and CDs, electronics enthusiasts, and anyone interested in optimal storage conditions for sensitive materials affected by humidity.

If I have a dvd disk inside those plastic boxes suitable for dvd disks in black, if I have an electronic board inside a bag or papers inside any plastic bag and after that all of them inside a closed cardboard box when I closed the cardboard box or bag or dvdbox it was in rainy or humid weather or even dry but with some humidity but in rainy season the humidity entered the box, bag or dvdbox when that climate is changed from rainy and one gone to hot and dry (31-35C) is the moisture that is inside the cardboard box, inside the bags and inside the dvdbox evaporated or does this only happen if you heat them intensely? that is, does the change to a dry and hot climate dry or not these items of moisture deposited on them?

This is a diffusion question and the time scales depend upon the exact materials involved.

Sentences are a useful part of grammar.

Water molecules will move at different rates through plastic bags, depending on the grade of the plastic.

Dry plastic bags are brittle. Plastic is preserved by the presence of excess water, which is a plasticizer for PE.
Paper and cardboard act as a reservoir for water vapour, that prevents local condensation by virtue of the huge surface area of cellulose fibres.
That leads to a complex relationship.

(Note -- this turns out to be a well known and prolific sockpuppet who seems to have mental fixations on humidity and his DVD/CD collection. Accordingly this latest sockpuppet has been shown the door.)
