Scary white substance on Polyethylene Sleeves

I hope that it's not anthrax or ricin!

Used that instead of a mirror?

I’m just hoping that Polyethelyne will eventually not be found out to be just as bad as PVC 

Good one @thecarpathian . Back in the day, we used whatever was handy, right?

@roxy54 ,

Why, whatever do you mean??😁

My new band name is Scary White Substance and the first album title is "Panicky Boomer"

Jesus

Maybe a thin outside/exterior dusting of ???  to control sticking during the manufacturing process (like cellulite added to pre-shredded cheese and mold release  used when pressing records)?

Perhaps a reaction between your wallpapers and the Poly?

You maybe right on… an email reply today from sleeve city…

Thank you for contacting us.  This is something that we have seen occasionally over the years.  Per the manufacturer, the powder substance will not do any harm to the records, but it is an ingredient used to avoid the film from adhering together.  I hope this helps.  Please contact us if you have any additional questions.

The hint is in the name!

the powder substance will not do any harm to the records, but it is an ingredient used to avoid the film from adhering together. 

I wonder if that applies to the "Living Stereo" records as well.
