How long does an unopened package stay good for?

well sealed/packaged, we sprouted them and ate it up right away so do not know shelf life

In my experience, as long as it stays in cool and dry place. It can stay good for a year or more

I store seeds in dry cool place with no sun, and they are good until gone. I stock 2 different varietes and use 1 to 1 1/2 tablespoon per batch once a week. My Amazon history shows I reorder every 3-4 months.

I don't have LOTs of experience here. But the short answer is weeks although I would think the beans (larger) would do better than the "seeds" (broccoli, clover, etc.). I go through about a half-cup in a week and gone through one "bean" bag and one "seed" bag and had no spoilage issue.

Unopened, they last a long time and would be good for storage. Opened, they don't. It depends on how humid your climate is, but I'm in a very dry place, and they sog after a few days to a week.

Yes. There is an expiration date on the package. It is still usable after it expires, but the colors are a bit off.

As packaged they should last awile. If you open it to see what's in it, you might want to put it in the freezer. I'm extremely satisfied with my purchase and would recommend it to anyone.

The package has a use by date. I've had mine on a shelf for up to a year and it was just fine.

If There was an expiration date it should be either on the side or bottom of the box & usually you should still be able to still use them a little past the date listed as long as they are still intact.

Good question! I order them once a month. So from my experience they last at least a month in a ziploc bag. But unopened I think for much longer as they are dried.

They have the expiration date printed on the filter package. Usually a few years. I usually keep them about 2-4 weeks after opening, depending on the spray environment. I keep them in an air tight box when not in use. You can also use zip lock bags; otherwise they will become contaminated. If the environment is not adequately ventilated the useable time can be greatly reduced also.

At least a few months. I use them too quickly to find out, but I used a leftover box after about three months and they were good as new.

On the package they sent me the date was 2020 (at least 5 years from now.) You can however use them long past the expiration date as long as the package is not compromised.

They can last for several months if unopened. Longer if refrigerated prior to opening.

All of the strips are individually wrapped. So when you open a strip you should intend to use it immediately. There are expiration dates on each individual package, I believe they are good for over a year.

Yes, unopened is absolutely the best way because they don't last super long otherwise (ask me how I know). I am almost 100% sure they do not have to be refrigerated while still unopened.

As long as the package remains sealed, probably at least several months . . . I've had it sit that long during hot summers with no ill effects.

I cannot remember the total amount of time but it is quite a long time. I had boxes for over a month that were still good. :O)

I just received one a couple weeks ago, love it btw. It comes rolled up in a vacuum sealed plastic bag inside a card board box. I don't see any reason why you can't leave it packaged for as long as you need.

This is just a guess because I threw the packaging out.3 years after using from date on package.Left unused however I would think it would last much longer,maybe even until use.
