Mylar vs “humidity-control packaging” isn’t a fair fight… because they’re doing different jobs.
Mylar = barrier.
Great for blocking outside air and smells.
But inside the bag, RH can still drift based on what you put in, how full it is, and how often it gets opened.
Humidity-control packaging = barrier + built-in control.
With 𝐫𝐮𝐤𝐬𝐚𝐤®, the 2-way humidity control fiber is part of the bag, so it helps buffer the microclimate inside the package.
No loose packs to forget, shift around, or swap between batches.
Not saying mylar is “bad.”
This is just what changes when humidity control becomes part of the packaging: 𝐥𝐞𝐬𝐬 𝐡𝐚𝐧𝐝𝐥𝐢𝐧𝐠, 𝐟𝐞𝐰𝐞𝐫 𝐬𝐭𝐞𝐩𝐬, 𝐦𝐨𝐫𝐞 𝐜𝐨𝐧𝐬𝐢𝐬𝐭𝐞𝐧𝐜𝐲.
