Store DVD-R inside a closed plastic bag?
 

exist any problem if I store the cd / dvd / mdisc with case inside a closed plastic bag? I keep the bag in a ventilated place and a little humid

Plastic traps moisture. That's a horrible idea. Don't do that.

But I did a test I put a hygrometer inside the closed bag and the humidity is low then the humidity comes out of the bag

If the humidity inside the bag is better than outside, you have some really terrible conditions there in Brazil. :eeks:

I placed the hygrometer inside the bag and the humidity inside the bag is the same outside the bag, if inside the bag the hygrometer shows 50%, outside the bag is also 50%, if the outside of the bag shows 60%, inside the bag shows 60%, I put the bag in a ventilated environment with low humidity, humidity only gets high on rainy days regardless of inside or outside the bag, there are bags that let the air in, the air is renewed, with this test is correct ?

Then it sounds as if that bag is useless, if outside RH% matches inside.

The bag is useful because it protects the disks from dust and insects

Ah. Yes, it can do that. However, it's still not what I would do. But I guess you must make the best of your conditions. Brazil has some pretty rough non-controlled climates for optical media.

Can I store the discs inside these plastic bags without problems? My test I put the hygrometer inside the bag and closed the bag in the bathroom (local humidity) I placed the bag in a ventilated environment and the humidity dropped, I see that the humidity inside the bag is similar to moisture out of the bag

What kind of bag retains moisture?

Temperature changes will cause any plastic bag to have moisture bead up inside. This also assume the item inside has moisture to excrete. If 100% dry, no moisture can build up.

I'd rather store in a cardboard box. Cardboard will absorb the moisture, not trap it.

1 Can not I store the discs inside the bag? I will have problems?

this test higrometer is not reliable?

2 If inside the bag has moisture because of rain, on dry days will have a change of moisture by dry air inside the bag? This bag is not vacuumed I tied the bag

1 If I store the disks in that bag tie close the bag and put the bag in a ventilated and dry place the moisture humidity inside the bag will get stuck or will it leave having an air exchange?

2 Even if there is some moisture inside the bag, if the outside environment is dry the dry air enters the bag and the humid air leaves the bag?

3 How to store: DVD or MDisc DVDR disc inside dvd case black Amaray> dvd case Amaray black inside a plastic bag tied closed the same as the photo bag > plastic bag inside a closed cardboard box> cardboard box in an open environment And ventilated room (not air conditioned)

4 Is there any test I can do with a closed bag to find out if there is condensed moisture inside the bag or if the dry air enters the bag releasing moist air?

I would just purchase an aluminum hard DVD case and leave a hygrometer inside to check the humidity levels now and then. If the humidity is too high you can lower it with silica gel packets. And if you have an insect problem using cardboard boxes might invite unwelcome guests.

Does anyone answer my questions above?

Great idea. Why didn't I think of that? :smack:

I can't answer this. I've put a bag over my head. :laugh:

Please friend answer

1 the dvdr / mdisc dvdr are inside a black dvd case and the case is inside a closed plastic bag just like the photo and the bag is inside a cardboard box If I need to remove the bags it is necessary to do several scan read Test, jitter, PIE, PIF because the humidity increased their level to the point of causing a great degradation?

2 I did what I thought of placing the discs, case and bag inside a cardboard box in an open and ventilated place thinking that the moisture would go down inside the bag

I am testing a hygrometer inside the closed bag, I closed the bag in a humid place and placed it in a ventilated and open place, I see the humidity inside the bag go down although a little slow, if it rains the humidity inside the bag go up, if it does not rain the Humidity inside the bag will fall, here where I live northeastern Brazil for most of the year the climate is dry without rain, if I keep the cases of dvd with the cd / dvd / mdisc inside that bag closed the discs will die fast and Will not have the estimated useful life of the manufacturer or have no problem would be the same as storing without a bag?

If you are using a bag like the one at the beginning of this post, I don't see how the bag can have an air-tight seal. The humidity will go up and down with the climate, as you found. Nevertheless, if you store it in an opaque bag it might still reduce the amount of light reaching the discs. Getting an aluminum/metal case would be better.

Yes I use a bag just like the photos, it does not have a sealed seal I tie it I closed the bag and I put the bag in an open and ventilated room, with the hygrometer inside the bag I see that the humidity goes up and down with the weather But the humidity goes into balance with the outside after a few hours or a few days, the cd / dvd / mdisc is inside a black dvd case and the case inside the bag, this bag will reduce the useful life of the discs because of Humidity or not? The humidity harms the useful life of the cd / dvd / dvdr mdisc is the constant humidity every day or the humidity in a few days during the year?

1 I did a test with a plastic bag, I put a hygrometer inside the bag and I tied it and closed the bag, put the bag in an open and ventilated room, if the day is rainy the high humidity inside the bag and out of the bag Also, if the day is dry the humidity is low inside the bag, the humidity fits inside the bag with the current humidity, this adjustment is a bit slower than the external humidity, matter of hours or a few days, I live in the region Northeast of brazil most of the year is hot and dry if I continue to store the dvdr.cdr and mdisc inside the case of dvd and the case inside a plastic bag closed the disc will live little or he will have the same life What out of the bag? The bag is inside a cardboard box is a ventilated room

2 Does any present (hours, A few days until drying) moisture damage and reduce the useful life of the cd / dvd / mdisc or just constant humidity every day and accumulated damages these media? If today has humidity and tomorrow is dry has a big impact on the useful life of cdr / dvdr / mdisc dvdr or not?

Yes. Constant or not, it harms. :2cents:

1 a plastic bag just like the photo lets in moisture on rainy day, moisture comes out of the bag with the day dry? Do you decide to keep the closed bag inside a box and the box in a ventilated room?

2 Does the black dvd case have any moisture protection? I keep the disc inside the case and the case inside the bag, the humidity and condensation air enters in the case what case inside bag closed?

More like "impedance" rather than protection. It will slow down moisture from entering, but eventually it will leak through the closed case. DVD cases have venting under the clear window, so it's not sealed. And it really shouldn't be, to prevent moisture buildup.

You live in a moist area. To do better than the cases suggested, you'll have to move. I hear Iceland is nice.

Put it in a SEALED container with a desiccant pack.

I do not live in the humid area of ​​Brazil, the northeast region of Ceará is dry but in a few months of the year there is rain season

My test with a hygrometer was this:
I put a digital hygrometer inside the closed plastic bag and I put the bag closed inside a closed cardboard box, put the box in the same room where the disks are stored under the same conditions in an open and ventilated room, I realize that in the rain The humidity in the hygrometer goes up 70, 80, 90% quickly and when it does not rain and the air is dried slowly the humidity falls (70, 60, 50%) until it equals or near the external humidity of the room, Bag will always be smaller

Do you think this my storage mode for cds / dvds / mdiscs will compromise their durability and life expectancy? All the discs are inside dvd cases the cases are inside bags and the bags inside boxes

I just do not think the bag is doing anything for you.

If I keep them in the bag will the disk die early and have a short lifespan? I put in the bag to protect from dust and insects because it is the only option I have but if this would damage long term storage I will have to not use the bag

A bag won't make it degrade any slower.

The closed bag will cause the discs to degrade faster because of the moisture humidity inside the bag or not, outside the bag degrades little moisture humidity inside the bag degrades too much moisture?
