The Ziplock freezer bags are food safe so shouldn’t damage your scarves for short term storage.
However no plastic is good for long term storage of fabric.
H at one time, if I remember correctly, offered a silk scarf travel envelope. This was quite some time ago & pricey.
You could make your own with an old trashed scarf?
When DH’s dry cleaner retired they sold him a couple of blocks of wedding dress archive tissue paper. You know for permanent wedding gown storage in a presentation box.
Perhaps ask your dry cleaner if they could sell you a few sheets?
All terrific ideas--thanks for the suggestions! Definitely going to think about making or finding a travel envelope...
Plastic is OK if it can breathe - cut the corners off the bags and any plastic fumes (outgassing) will escape AND moisture will escape
Plastic is bad about trapping moisture
IMHO, orange boxes fit very tight and also trap moisture, you can buy little bags of moisture absorbing crystals at Amazon, not expensive. The same type of packets that seem to be shipped with everything and one tosses. I did find articles from museums saying these were OK for textile storage
Amazon also sells acid free tissue paper - cheap
Ziplocs are fine unless you stack up too many , then they start to slide off one another
Ooh, wouldn't have thought of cutting off the corners. And have been wondering if something should be added to the orange boxes long-term, either for moisture or moth repellant.
