I dunno. A Ziploc might be too complex for a boomer. Proly just wrapped in layers of Saran-wrap.
Most Boomers can't manipulate their indexes well enough to get Saran Wrap peeling from the roll, and those new-fangled zipper baggy things, well.........
And that's why they use wax paper, ya know like how they used to wrap their sandwiches up to bring to work.
