I'm sure it's not cellophane, but it reminds me of that type of material, and very thin, like expensive christmas wrapping.
All of the bags of hops I receive on my first hop purchase were in very thin, non vacuumed bags.
I ordered either 2 of 4 ounces of Polaris to try on my last order, and they were packaged very well, like hops direct.
Don't know what to tell you. I can post pics if needed.
