All polymers that are commonly manufactured as films allow diffusion of water vapour at surprisingly high rates - far too high for even short term storage of moisture-sensitive items.
To improve moisture barrier properties they are often coated - often with a vinylidene chloride based polymer. The ultimate barrier coating for films is a metal though - usually aluminum applied as a vapour. Crisps/potato chips are not in metallised film bags for nothing, and it isn't primarily appearance.

Are gun cases moisture proof?
no
What is moisture in spanish?
It's either 'humedad' or 'vapor'
Where do hurricanes get their moisture?
The moisture that fuels a hurricane is water vapor that comes from warm ocean water.
How is vapor created?
water that is a liquid, evaporates into the air. and becomes dense forming moisture (water vapor)
Do you need a vapor barrier on exterior walls for proper insulation and moisture control?
Yes, a vapor barrier is needed on exterior walls for proper insulation and moisture control. It helps prevent moisture from entering the walls and causing damage.
How do you control moisture vapor in concrete?
2 options. Let it finish curing or apply a moisture barrier.
What is a vapor barrier under a wood floor?
Vapor is another word for moisture. A vapor barrier is a sheet of plastic covering the entire surface under the floor to prevent moisture from causing the floor to warp or absorb stains. You would typically use a vapor barrier in basements with concrete floors.
What is the purpose of a basement wall vapor barrier and how does it help in preventing moisture issues in the basement?
A basement wall vapor barrier is used to prevent moisture from seeping through the walls into the basement. It helps by blocking the passage of water vapor, which can reduce the risk of mold growth, dampness, and other moisture-related problems in the basement.
Does water have moisture?
Water itself is not moist, as moisture refers to the presence of moisture or water vapor in the air. However, water can contribute to moisture when it evaporates and increases humidity in the air.
What are some ways moisture is present in the atmosphere?
water vapor and condensation
What is the difference between a vapor barrier and a moisture barrier, and how do they each function in protecting against moisture intrusion?
A vapor barrier is designed to prevent the movement of water vapor through a material, while a moisture barrier is meant to block liquid water. Vapor barriers are typically used in areas with high humidity to prevent condensation, while moisture barriers are used to protect against leaks and water seepage. Both barriers help to protect against moisture intrusion by creating a barrier that prevents water from entering a building's structure.
Why should plaster of Paris stored in moisture proof container?
Because moisture makes it set hard
